From debugging an existing system to designing an entirely new software application, a day in the life of a software engineer is filled with various challenges and complexities. The one skill that glues these disparate tasks together and makes them manageable? Problem solving . 

Throughout this blog post, we’ll explore why problem-solving skills are so critical for software engineers, delve into the techniques they use to address complex challenges, and discuss how hiring managers can identify these skills during the hiring process. 

What Is Problem Solving?

But what exactly is problem solving in the context of software engineering? How does it work, and why is it so important?

Problem solving, in the simplest terms, is the process of identifying a problem, analyzing it, and finding the most effective solution to overcome it. For software engineers, this process is deeply embedded in their daily workflow. It could be something as simple as figuring out why a piece of code isn’t working as expected, or something as complex as designing the architecture for a new software system. 

In a world where technology is evolving at a blistering pace, the complexity and volume of problems that software engineers face are also growing. As such, the ability to tackle these issues head-on and find innovative solutions is not only a handy skill — it’s a necessity. 

The Importance of Problem-Solving Skills for Software Engineers

Problem-solving isn’t just another ability that software engineers pull out of their toolkits when they encounter a bug or a system failure. It’s a constant, ongoing process that’s intrinsic to every aspect of their work. Let’s break down why this skill is so critical.

Driving Development Forward

Without problem solving, software development would hit a standstill. Every new feature, every optimization, and every bug fix is a problem that needs solving. Whether it’s a performance issue that needs diagnosing or a user interface that needs improving, the capacity to tackle and solve these problems is what keeps the wheels of development turning.

It’s estimated that 60% of software development lifecycle costs are related to maintenance tasks, including debugging and problem solving. This highlights how pivotal this skill is to the everyday functioning and advancement of software systems.

Innovation and Optimization

The importance of problem solving isn’t confined to reactive scenarios; it also plays a major role in proactive, innovative initiatives . Software engineers often need to think outside the box to come up with creative solutions, whether it’s optimizing an algorithm to run faster or designing a new feature to meet customer needs. These are all forms of problem solving.

Consider the development of the modern smartphone. It wasn’t born out of a pre-existing issue but was a solution to a problem people didn’t realize they had — a device that combined communication, entertainment, and productivity into one handheld tool.

Increasing Efficiency and Productivity

Good problem-solving skills can save a lot of time and resources. Effective problem-solvers are adept at dissecting an issue to understand its root cause, thus reducing the time spent on trial and error. This efficiency means projects move faster, releases happen sooner, and businesses stay ahead of their competition.

Improving Software Quality

Problem solving also plays a significant role in enhancing the quality of the end product. By tackling the root causes of bugs and system failures, software engineers can deliver reliable, high-performing software. This is critical because, according to the Consortium for Information and Software Quality, poor quality software in the U.S. in 2022 cost at least $2.41 trillion in operational issues, wasted developer time, and other related problems.

Problem-Solving Techniques in Software Engineering

So how do software engineers go about tackling these complex challenges? Let’s explore some of the key problem-solving techniques, theories, and processes they commonly use.

Decomposition

Breaking down a problem into smaller, manageable parts is one of the first steps in the problem-solving process. It’s like dealing with a complicated puzzle. You don’t try to solve it all at once. Instead, you separate the pieces, group them based on similarities, and then start working on the smaller sets. This method allows software engineers to handle complex issues without being overwhelmed and makes it easier to identify where things might be going wrong.

Abstraction

In the realm of software engineering, abstraction means focusing on the necessary information only and ignoring irrelevant details. It is a way of simplifying complex systems to make them easier to understand and manage. For instance, a software engineer might ignore the details of how a database works to focus on the information it holds and how to retrieve or modify that information.

Algorithmic Thinking

At its core, software engineering is about creating algorithms — step-by-step procedures to solve a problem or accomplish a goal. Algorithmic thinking involves conceiving and expressing these procedures clearly and accurately and viewing every problem through an algorithmic lens. A well-designed algorithm not only solves the problem at hand but also does so efficiently, saving computational resources.

Parallel Thinking

Parallel thinking is a structured process where team members think in the same direction at the same time, allowing for more organized discussion and collaboration. It’s an approach popularized by Edward de Bono with the “ Six Thinking Hats ” technique, where each “hat” represents a different style of thinking.

In the context of software engineering, parallel thinking can be highly effective for problem solving. For instance, when dealing with a complex issue, the team can use the “White Hat” to focus solely on the data and facts about the problem, then the “Black Hat” to consider potential problems with a proposed solution, and so on. This structured approach can lead to more comprehensive analysis and more effective solutions, and it ensures that everyone’s perspectives are considered.

This is the process of identifying and fixing errors in code . Debugging involves carefully reviewing the code, reproducing and analyzing the error, and then making necessary modifications to rectify the problem. It’s a key part of maintaining and improving software quality.

Testing and Validation

Testing is an essential part of problem solving in software engineering. Engineers use a variety of tests to verify that their code works as expected and to uncover any potential issues. These range from unit tests that check individual components of the code to integration tests that ensure the pieces work well together. Validation, on the other hand, ensures that the solution not only works but also fulfills the intended requirements and objectives.

Evaluating Problem-Solving Skills

We’ve examined the importance of problem-solving in the work of a software engineer and explored various techniques software engineers employ to approach complex challenges. Now, let’s delve into how hiring teams can identify and evaluate problem-solving skills during the hiring process.

Recognizing Problem-Solving Skills in Candidates

How can you tell if a candidate is a good problem solver? Look for these indicators:

  • Previous Experience: A history of dealing with complex, challenging projects is often a good sign. Ask the candidate to discuss a difficult problem they faced in a previous role and how they solved it.
  • Problem-Solving Questions: During interviews, pose hypothetical scenarios or present real problems your company has faced. Ask candidates to explain how they would tackle these issues. You’re not just looking for a correct solution but the thought process that led them there.
  • Technical Tests: Coding challenges and other technical tests can provide insight into a candidate’s problem-solving abilities. Consider leveraging a platform for assessing these skills in a realistic, job-related context.

Assessing Problem-Solving Skills

Once you’ve identified potential problem solvers, here are a few ways you can assess their skills:

  • Solution Effectiveness: Did the candidate solve the problem? How efficient and effective is their solution?
  • Approach and Process: Go beyond whether or not they solved the problem and examine how they arrived at their solution. Did they break the problem down into manageable parts? Did they consider different perspectives and possibilities?
  • Communication: A good problem solver can explain their thought process clearly. Can the candidate effectively communicate how they arrived at their solution and why they chose it?
  • Adaptability: Problem-solving often involves a degree of trial and error. How does the candidate handle roadblocks? Do they adapt their approach based on new information or feedback?

Hiring managers play a crucial role in identifying and fostering problem-solving skills within their teams. By focusing on these abilities during the hiring process, companies can build teams that are more capable, innovative, and resilient.

Key Takeaways

As you can see, problem solving plays a pivotal role in software engineering. Far from being an occasional requirement, it is the lifeblood that drives development forward, catalyzes innovation, and delivers of quality software. 

By leveraging problem-solving techniques, software engineers employ a powerful suite of strategies to overcome complex challenges. But mastering these techniques isn’t simple feat. It requires a learning mindset, regular practice, collaboration, reflective thinking, resilience, and a commitment to staying updated with industry trends. 

For hiring managers and team leads, recognizing these skills and fostering a culture that values and nurtures problem solving is key. It’s this emphasis on problem solving that can differentiate an average team from a high-performing one and an ordinary product from an industry-leading one.

At the end of the day, software engineering is fundamentally about solving problems — problems that matter to businesses, to users, and to the wider society. And it’s the proficient problem solvers who stand at the forefront of this dynamic field, turning challenges into opportunities, and ideas into reality.

  • Understanding the Problem

Problem Solving

Today, we use computers in every field for various purposes. But, we know that they cannot solve the problems all by themselves. Furthermore, we have to give step by step instructions to the computer for solving the problem. We can define problem-solving as a process of understanding the problem, designing an algorithm for it, and finally implementing the solution to it.

Therefore, we can say that a successful problem-solving process depends on the following factors:

  • understanding the problem and defining it precisely.
  • designing a proper algorithm (solution) for it.
  • implementing the algorithm successfully.

When the problems are easy we can easily search out a solution. Whereas, complex problems require step by step process to solve. Hence, this means that we have to apply problem-solving techniques to solve the problem. Furthermore, this starts with finding a precise definition of the problem and ends with a successful solution. Here, we will study understanding the problem in detail.

It is very obvious that before finding the solution we should understand the problem well. Moreover, if we fail to understand the problem we may end up with a useless solution for it. Hence, a wrong solution will not solve our purpose of problem-solving. Therefore, we need to read the problem carefully and decide the different functions which the solution will contain.

Moreover, we need to understand that what is the required output and how we can generate it. Besides, for proper output, we surely need an input. The input can be single or multiple as per the problem. Hence, it is quite important to maintain the necessary relationship between the input and the output.

Furthermore, we need to keep in mind that there should be all the number of inputs required to produce the output. At the same time, the programmer should make sure that the number of inputs should be limited. Moreover, any irrelevant input will result in consuming more space and time. Hence, unnecessary inputs should be avoided. Therefore, we can say that spotting the minimum number of input for the correct output is an important point in understanding the problem.

Important points in Understanding the Problem

Some of the important points that we should keep in mind while understanding the problem are as follows:

  • Read the problem very carefully.
  • Identify the functions that the solution (algorithm) should have.
  • Identify the required output.
  • Find a way to produce the required output.
  • Draw a proper relationship between the input and output.
  • Take all the necessary number of inputs.
  • Avoid unnecessary inputs.
  • Identify the correct number of the required input.

Further steps in problem-solving

After understanding the problem, the further steps are as follows:

Designing an algorithm

After understanding the relationship between input and output and the functionalities required we have to design an algorithm. Furthermore, the algorithm should contain all the necessary functions to solve the problem. Moreover, it should produce a proper output for every input.

Implementing the algorithm

After designing the algorithm we should implement and design a program to solve the problem. We can develop the program using any programming language.

After developing the program we should run and test if it produces the correct output.

Problem Solving

Solving problems is the core of computer science. Programmers must first understand how a human solves a problem, then understand how to translate this "algorithm" into something a computer can do, and finally how to "write" the specific syntax (required by a computer) to get the job done. It is sometimes the case that a machine will solve a problem in a completely different way than a human.

Computer Programmers are problem solvers. In order to solve a problem on a computer you must:

Know how to represent the information (data) describing the problem.

Determine the steps to transform the information from one representation into another.

Information Representation

A computer, at heart, is really dumb. It can only really know about a few things... numbers, characters, booleans, and lists (called arrays) of these items. (See Data Types). Everything else must be "approximated" by combinations of these data types.

A good programmer will "encode" all the "facts" necessary to represent a problem in variables (See Variables). Further, there are "good ways" and "bad ways" to encode information. Good ways allow the computer to easily "compute" new information.

An algorithm (see Algorithm) is a set of specific steps to solve a problem. Think of it this way: if you were to tell your 3 year old neice to play your favorite song on the piano (assuming the neice has never played a piano), you would have to tell her where the piano was, and how to sit on the bench, and how to open the cover, and which keys to press, and which order to press them in, etc, etc, etc.

The core of what good programmers do is being able to define the steps necessary to accomplish a goal. Unfortunately, a computer, only knows a very restricted and limited set of possible steps. For example a computer can add two numbers. But if you want to find the average of two numbers, this is beyond the basic capabilities of a computer. To find the average, you must:

  • First: Add the two numbers and save this result in a variable
  • Then: Divide this new number the number two, and save this result in a variable.
  • Finally: provide this number to the rest of the program (or print it for the user).

We "compute" all the time. Computing is the act of solving problems (or coming up with a plan to solve problems) in an organized manner. We don't need computers to "compute". We can use our own brain.

Encapsulation and Abstraction and Complexity Hiding

Computer scientists like to use the fancy word "Encapsulation" to show how smart we are. This is just a term for things we do as humans every day. It is combined with another fancy term: "Abstraction".

Abstraction is the idea of "ignoring the details". For example, a forest is really a vastly complex ecosystem containing trees, animals, water paths, etc, etc, etc. But to a computer scientist (and to a normal person), its just "a forest".

For example, if your professor needs a cup of coffee, and asks you the single item: "Get me a cup of coffee", he has used both encapsulation and abstraction. The number of steps required to actually get the coffee are enumerable. Including, getting up, walking down the hall, getting in your car, driving to a coffee stand, paying for the coffee, etc, etc, etc. Further, the idea of what a cup of coffee is, is abstract. Do you bring a mug of coffee, or a Styrofoam cup? Is it caffeinated or not? Is it freshly brewed or from concentrate? Does it come from Africa or America?

All of this information is TOO MUCH and we would quickly be unable to funciton if we had to remember all of these details. Thus we "abstract away" the details and only remember the few important items.

This brings us to the idea of "Complexity Hiding". Complexity hiding is the idea that most of the times details don't matter. In a computer program, as simple an idea as drawing a square on the screen involves hundreds (if not thousands) of (low level) computer instructions. Again, a person couldn't possible create interesting programs if every time they wanted to do something, they had to re-write (correctly) every one of those instructions. By "ecapsulating" what is meant by "draw square" and "reusing" this operation over and over again, we make programming tractable.

Encapsulation

The idea behind encapsulation is to store the information necessary to a particular idea in a set of variables associated with a single "object". We then create functions to manipulate this object, regardless of what the actual data is. From that point on, we treat the idea from a "high level" rather than worry about all the parts (data) and actions (functions) necessary to represent the object in a computer.

Brute Force

Brute force is a technique for solving problems that relies on a computers speed (how fast it can repeat steps) to solve a problem. For example, if you wanted to know how many times the number 8 goes into the number 100, you could do the following:

Of course this is a silly way for a computer (or a human) to solve this problem. The real way we would do it is:

When in doubt, you can often use "brute force" to solve a problem, but it often saves time (at least computer time) to think about the problem and solve it in an elegant manner.

  • Problem Solving Theories

Problem solving can be defined as the process of a problem analysis and resolving it in the best way possible for that situation.

This process contains analysing the problem (root cause analysis), defining countermeasures for the problem and implementing the right solution for that situation.

For problem solving, people need critical thinking and analytical skills . Everybody within a organization or company can benefit from having good skills because there are always problems.

There have been lots of scientific and practical studies from a learning point of view. Some of the problem solving techniques developed and used in artificial intelligence (AI) , computer science, engineering, mathematics, or medicine are related to mental techniques studied in psychology.

What are the most known and used techniques and methods? What are their success stories and practical tips when you apply these? These posts are all about great tools and methods that can help you to achieve your goal or understand certain aspects that come with solving problems.

What is Problem Solving Algorithm?

Computers are used for solving various day-to-day problems and thus problem solving is an essential skill that a computer science student should know. It is pertinent to mention that computers themselves cannot solve a problem. Precise step-by-step instructions should be given by us to solve the problem.

Problem Solving Algorithm

Thus, the success of a computer in solving a problem depends on how correctly and precisely we define the problem, design a solution (algorithm) and implement the solution (program) using a programming language.

Thus, problem solving is the process of identifying a problem, developing an algorithm for the identified problem and finally implementing the algorithm to develop a computer program.

Definition of Problem Solving Algorithm

These are some simple definition of problem solving algorithm which given below:

Steps for Problem Solving

When problems are straightforward and easy, we can easily find the solution. But a complex problem requires a methodical approach to find the right solution. In other words, we have to apply problem solving techniques.

Problem solving begins with the precise identification of the problem and ends with a complete working solution in terms of a program or software. Key steps required for solving a problem using a computer.

For Example: Suppose while driving, a vehicle starts making a strange noise. We might not know how to solve the problem right away. First, we need to identify from where the noise is coming? In case the problem cannot be solved by us, then we need to take the vehicle to a mechanic.

The mechanic will analyse the problem to identify the source of the noise, make a plan about the work to be done and finally repair the vehicle in order to remove the noise. From the example, it is explicit that, finding the solution to a problem might consist of multiple steps.

Following are Steps for Problem Solving :

Analysing the Problem

Developing an algorithm, testing and debugging.

Steps for Problem Solving

It is important to clearly understand a problem before we begin to find the solution for it. If we are not clear as to what is to be solved, we may end up developing a program which may not solve our purpose.

Thus, we need to read and analyse the problem statement carefully in order to list the principal components of the problem and decide the core functionalities that our solution should have. By analysing a problem, we would be able to figure out what are the inputs that our program should accept and the outputs that it should produce.

It is essential to device a solution before writing a program code for a given problem. The solution is represented in natural language and is called an algorithm. We can imagine an algorithm like a very well-written recipe for a dish, with clearly defined steps that, if followed, one will end up preparing the dish.

We start with a tentative solution plan and keep on refining the algorithm until the algorithm is able to capture all the aspects of the desired solution. For a given problem, more than one algorithm is possible and we have to select the most suitable solution.

After finalising the algorithm, we need to convert the algorithm into the format which can be understood by the computer to generate the desired solution. Different high level programming languages can be used for writing a program. It is equally important to record the details of the coding procedures followed and document the solution. This is helpful when revisiting the programs at a later stage.

The program created should be tested on various parameters. The program should meet the requirements of the user. It must respond within the expected time. It should generate correct output for all possible inputs. In the presence of syntactical errors, no output will be obtained. In case the output generated is incorrect, then the program should be checked for logical errors, if any.

Software industry follows standardised testing methods like unit or component testing, integration testing, system testing, and acceptance testing while developing complex applications. This is to ensure that the software meets all the business and technical requirements and works as expected.

The errors or defects found in the testing phases are debugged or rectified and the program is again tested. This continues till all the errors are removed from the program. Once the software application has been developed, tested and delivered to the user, still problems in terms of functioning can come up and need to be resolved from time to time.

The maintenance of the solution, thus, involves fixing the problems faced by the user, answering the queries of the user and even serving the request for addition or modification of features.

Representation of Algorithms

Using their algorithmic thinking skills, the software designers or programmers analyse the problem and identify the logical steps that need to be followed to reach a solution. Once the steps are identified, the need is to write down these steps along with the required input and desired output.

There are two common methods of representing an algorithm —flowchart and pseudocode. Either of the methods can be used to represent an algorithm while keeping in mind the following:

  • It showcases the logic of the problem solution, excluding any implementational details.
  • It clearly reveals the flow of control during execution of the program.

A flowchart is a visual representation of an algorithm . A flowchart is a diagram made up of boxes, diamonds and other shapes, connected by arrows. Each shape represents a step of the solution process and the arrow represents the order or link among the steps.

A flow chart is a step by step diagrammatic representation of the logic paths to solve a given problem. Or A flowchart is visual or graphical representation of an algorithm .

The flowcharts are pictorial representation of the methods to b used to solve a given problem and help a great deal to analyze the problem and plan its solution in a systematic and orderly manner. A flowchart when translated in to a proper computer language, results in a complete program.

Advantages of Flowcharts:

  • The flowchart shows the logic of a problem displayed in pictorial fashion which felicitates easier checking of an algorithm
  • The Flowchart is good means of communication to other users. It is also a compact means of recording an algorithm solution to a problem.
  • The flowchart allows the problem solver to break the problem into parts. These parts can be connected to make master chart.
  • The flowchart is a permanent record of the solution which can be consulted at a later time.

Differences between Algorithm and Flowchart

Pseudo code.

The Pseudo code is neither an algorithm nor a program. It is an abstract form of a program. It consists of English like statements which perform the specific operations. It is defined for an algorithm. It does not use any graphical representation.

In pseudo code , the program is represented in terms of words and phrases, but the syntax of program is not strictly followed.

Advantages of Pseudocode

  • Before writing codes in a high level language, a pseudocode of a program helps in representing the basic functionality of the intended program.
  • By writing the code first in a human readable language, the programmer safeguards against leaving out any important step. Besides, for non-programmers, actual programs are difficult to read and understand.
  • But pseudocode helps them to review the steps to confirm that the proposed implementation is going to achieve the desire output.

What Is Problem Solving?

Definition and importance.

Problem solving is the process of finding solutions to obstacles or challenges you encounter in your life or work. It is a crucial skill that allows you to tackle complex situations, adapt to changes, and overcome difficulties with ease. Mastering this ability will contribute to both your personal and professional growth, leading to more successful outcomes and better decision-making.

Problem-Solving Steps

The problem-solving process typically includes the following steps:

  • Identify the issue : Recognize the problem that needs to be solved.
  • Analyze the situation : Examine the issue in depth, gather all relevant information, and consider any limitations or constraints that may be present.
  • Generate potential solutions : Brainstorm a list of possible solutions to the issue, without immediately judging or evaluating them.
  • Evaluate options : Weigh the pros and cons of each potential solution, considering factors such as feasibility, effectiveness, and potential risks.
  • Select the best solution : Choose the option that best addresses the problem and aligns with your objectives.
  • Implement the solution : Put the selected solution into action and monitor the results to ensure it resolves the issue.
  • Review and learn : Reflect on the problem-solving process, identify any improvements or adjustments that can be made, and apply these learnings to future situations.

Defining the Problem

To start tackling a problem, first, identify and understand it. Analyzing the issue thoroughly helps to clarify its scope and nature. Ask questions to gather information and consider the problem from various angles. Some strategies to define the problem include:

  • Brainstorming with others
  • Asking the 5 Ws and 1 H (Who, What, When, Where, Why, and How)
  • Analyzing cause and effect
  • Creating a problem statement

Generating Solutions

Once the problem is clearly understood, brainstorm possible solutions. Think creatively and keep an open mind, as well as considering lessons from past experiences. Consider:

  • Creating a list of potential ideas to solve the problem
  • Grouping and categorizing similar solutions
  • Prioritizing potential solutions based on feasibility, cost, and resources required
  • Involving others to share diverse opinions and inputs

Evaluating and Selecting Solutions

Evaluate each potential solution, weighing its pros and cons. To facilitate decision-making, use techniques such as:

  • SWOT analysis (Strengths, Weaknesses, Opportunities, Threats)
  • Decision-making matrices
  • Pros and cons lists
  • Risk assessments

After evaluating, choose the most suitable solution based on effectiveness, cost, and time constraints.

Implementing and Monitoring the Solution

Implement the chosen solution and monitor its progress. Key actions include:

  • Communicating the solution to relevant parties
  • Setting timelines and milestones
  • Assigning tasks and responsibilities
  • Monitoring the solution and making adjustments as necessary
  • Evaluating the effectiveness of the solution after implementation

Utilize feedback from stakeholders and consider potential improvements. Remember that problem-solving is an ongoing process that can always be refined and enhanced.

Problem-Solving Techniques

During each step, you may find it helpful to utilize various problem-solving techniques, such as:

  • Brainstorming : A free-flowing, open-minded session where ideas are generated and listed without judgment, to encourage creativity and innovative thinking.
  • Root cause analysis : A method that explores the underlying causes of a problem to find the most effective solution rather than addressing superficial symptoms.
  • SWOT analysis : A tool used to evaluate the strengths, weaknesses, opportunities, and threats related to a problem or decision, providing a comprehensive view of the situation.
  • Mind mapping : A visual technique that uses diagrams to organize and connect ideas, helping to identify patterns, relationships, and possible solutions.

Brainstorming

When facing a problem, start by conducting a brainstorming session. Gather your team and encourage an open discussion where everyone contributes ideas, no matter how outlandish they may seem. This helps you:

  • Generate a diverse range of solutions
  • Encourage all team members to participate
  • Foster creative thinking

When brainstorming, remember to:

  • Reserve judgment until the session is over
  • Encourage wild ideas
  • Combine and improve upon ideas

Root Cause Analysis

For effective problem-solving, identifying the root cause of the issue at hand is crucial. Try these methods:

  • 5 Whys : Ask “why” five times to get to the underlying cause.
  • Fishbone Diagram : Create a diagram representing the problem and break it down into categories of potential causes.
  • Pareto Analysis : Determine the few most significant causes underlying the majority of problems.

SWOT Analysis

What is an algorithm, how do algorithms work, examples of algorithms, other interesting articles, frequently asked questions about algorithms.

An algorithm is a sequence of instructions that a computer must perform to solve a well-defined problem. It essentially defines what the computer needs to do and how to do it. Algorithms can instruct a computer how to perform a calculation, process data, or make a decision.

The best way to understand an algorithm is to think of it as a recipe that guides you through a series of well-defined actions to achieve a specific goal. Just like a recipe produces a replicable result, algorithms ensure consistent and reliable outcomes for a wide range of tasks in the digital realm.

And just like there are numerous ways to make, for example, chocolate chip cookies by following different steps or using slightly different ingredients, different algorithms can be designed to solve the same problem, with each taking a distinct approach but achieving the same result.

Algorithms are virtually everywhere around us. Examples include the following:

  • Search engines rely on algorithms to find and present relevant results as quickly as possible
  • Social media platforms use algorithms to prioritize the content that we see in our feeds, taking into account factors like our past behavior, the popularity of posts, and relevance.
  • With the help of algorithms, navigation apps determine the most efficient route for us to reach our destination.
  • It must be correct . In other words, it should take a given problem and provide the right answer or result, even if it stops working due to an error.
  • It must consist of clear, practical steps that can be completed in a limited time, whether by a person or the machine that must execute the algorithm. For example, the instructions in a cookie recipe might be considered sufficiently concrete for a human cook, but they would not be specific enough for programming an automated cookie-making machine.
  • There should be no confusion about which step comes next , even if choices must be made (e.g., when using “if” statements).
  • It must have a set number of steps (not an infinite number) that can be managed using loops (statements describing repeated actions or iterations).
  • It must eventually reach an endpoint and not get stuck in a never-ending loop.

Algorithms use a set of initial data or input , process it through a series of logical steps or rules, and produce the output (i.e., the outcome, decision, or result).

Algorithm boxes

If you want to make chocolate chip cookies, for instance, the input would be the ingredients and quantities, the process would be the recipe you choose to follow, and the output would be the cookies.

Algorithms are eventually expressed in a programming language that a computer can process. However, when an algorithm is being created, it will be people, not a computer, who will need to understand it. For this reason, as a first step, algorithms are written as plain instructions.

  • Input: the input data is a single-digit number (e.g., 5).
  • Transformation/processing: the algorithm takes the input (number 5) and performs the specific operation (i.e., multiplies the number by itself).
  • Output: the result of the calculation is the square of the input number, which, in this case, would be 25 (since 5 * 5 = 25).

We could express this as an algorithm in the following way:

Algorithm: Calculate the square of a number

  • Input the number (N) whose square you want to find.
  • Multiply the number (N) by itself.
  • Store the result of the multiplication in a variable (result).
  • Output the value of the variable (result), which represents the square of the input number.

It is important to keep in mind that an algorithm is not the same as a program or code. It is the logic or plan for solving a problem represented as a simple step-by-step description. Code is the implementation of the algorithm in a specific programming language (like C++ or Python), while a program is an implementation of code that instructs a computer on how to execute an algorithm and perform a task.

Instead of telling a computer exactly what to do, some algorithms allow computers to learn on their own and improve their performance on a specific task. These machine learning algorithms use data to identify patterns and make predictions or conduct data mining to uncover hidden insights in data that can inform business decisions.

Broadly speaking, there are three different types of algorithms:

  • Linear sequence algorithms follow a specific set or steps, one after the other. Just like following a recipe, each step depends on the success of the previous one.
  • For example, in the context of a cookie recipe, you would include the step “if the dough is too sticky, you might need to refrigerate it.”
  • For example, a looping algorithm could be used to handle the process of making multiple cookies from a single batch of dough. The algorithm would repeat a specific set of instructions to form and bake cookies until all the dough has been used.

Algorithms are fundamental tools for problem-solving in both the digital world and many real-life scenarios. Each time we try to solve a problem by breaking it down into smaller, manageable steps, we are in fact using algorithmic thinking.

  • Identify which clothes are clean.
  • Consider the weather forecast for the day.
  • Consider the occasion for which you are getting dressed (e.g., work or school etc.).
  • Consider personal preferences (e.g., style or which items match).

In mathematics, algorithms are standard methods for performing calculations or solving equations because they are efficient, reliable, and applicable to various situations.

Suppose you want to add the numbers 345 and 278. You would follow a set of steps (i.e., the standard algorithm for addition):

  • Write down the numbers so the digits align.
  • Start from the rightmost digits (the ones place) and add them together: 5 + 8 = 13. Write down the 3 and carry over the 1 to the next column.
  • Move to the next column (the tens place) and add the digits along with the carried-over value: 4 + 7 + 1 = 12. Write down the 2 and carry over the 1 to the next column.
  • Move to the leftmost column (the hundreds place) and add the digits along with the carried-over value: 3 + 2 + 1 = 6. Write down the 6.

The final result is 623

In computer science, an algorithm is a list of unambiguous instructions that specify successive steps to solve a problem or perform a task. Algorithms help computers execute tasks like playing games or sorting a list of numbers. In other words, computers use algorithms to understand what to do and give you the result you need.

Algorithms and artificial intelligence (AI) are not the same, however they are closely related.

  • Artificial intelligence is a broad term describing computer systems performing tasks usually associated with human intelligence like decision-making, pattern recognition, or learning from experience.
  • Algorithms are the instructions that AI uses to carry out these tasks, therefore we could say that algorithms are the building blocks of AI—even though AI involves more advanced capabilities beyond just following instructions.

Algorithms and computer programs are sometimes used interchangeably, but they refer to two distinct but interrelated concepts.

  • An algorithm is a step-by-step instruction for solving a problem that is precise yet general.
  • Computer programs are specific implementations of an algorithm in a specific programming language. In other words, the algorithm is the high-level description of an idea, while the program is the actual implementation of that idea.

Algorithms are valuable to us because they:

  • Form the basis of much of the technology we use in our daily lives, from mobile apps to search engines.
  • Power innovations in various industries that augment our abilities (e.g., AI assistants or medical diagnosis).
  • Help analyze large volumes of data, discover patterns and make informed decisions in a fast and efficient way, at a scale humans are simply not able to do.
  • Automate processes. By streamlining tasks, algorithms increase efficiency, reduce errors, and save valuable time.

Problem Solving Using Computer (Steps)

Computer based problem solving is a systematic process of designing, implementing and using programming tools during the problem solving stage. This method enables the computer system to be more intuitive with human logic than machine logic. Final outcome of this process is software tools which is dedicated to solve the problem under consideration. Software is just a collection of computer programs and programs are a set of instructions which guides computer’s hardware. These instructions need to be well specified for solving the problem. After its creation, the software should be error free and well documented. Software development is the process of creating such software, which satisfies end user’s requirements and needs.

The following six steps must be followed to solve a problem using computer.

  • Problem Analysis
  • Program Design - Algorithm, Flowchart and Pseudocode
  • Compilation and Execution
  • Debugging and Testing
  • Program Documentation

What is Coding? Computer Coding Definition

When you're starting your coding journey, one of the most exciting – and at times overwhelming – things about it is just how much there is to learn.

You'll discover different languages, frameworks, libraries, inventions and conventions.

One technology often requires knowledge of another one, and everything seems to be interconnected and intertwined.

With new technologies coming out often in such a fast paced and ever-changing industry, it can quickly get confusing for beginner coders.

When learning how to code, instead of just focusing on learning a specific technology, it can also help to learn the foundations – the building blocks – and to peel back the layers of abstraction to get to know the underlying principles that all these technologies have in common.

Understanding what coding is at a fundamental level will make solving problems easier and will give you a better understanding of how these technologies work underneath the hood.

In this article we will learn what coding is so you have a solid foundation on which to build.

How Do Computers Work?

Computers, when powered off, are just costly electronic machines. They're objects consisting of a bunch of metals, plastics, and other materials.

However, once you press the power button and they have gone through their power-up process, called booting up , they come to life.

Your computer turns into this extremely powerful machine. It's this electronic device that gets to do complicated tasks at mind boggling speeds that would be difficult, if not impossible, for humans to do.

Their screens are vibrant and active and there's a variety of buttons and icons ready to be clicked.

Computers and Electricity

Computers are powered and function with the help of electricity.

Electricity has only two states – it can be either turned on or off.

Electricity being turned on and flowing represents true, it has the 'on' state. On the other hand, when it's turned off and not flowing this represents false and the 'off' state.

It can only ever have one state at each point in time.

The two states of electricity are called Binary States , the prefix bi- meaning two.

What is Binary Code?

This concept of electrical charges and the existence of only two possible states ties in nicely with the numerical system computers use in their hardware. They use it to complete every single task they are given. It's called binary code and is made up of sequences of 0 s and 1 s.

Binary code by design corresponds directly with specific machine instructions, commands, and locations in the computer's memory. The computer then reads and interprets these instructions and then carries out particular tasks.

Computers are made up of a combination of thousands of tiny physical devices that act as electrical switches, called transistors.

Screenshot-2021-08-10-at-3.11.05-PM

These little electrical hardware components, the transistors, enable or disable the flow of electricity.

They can have either a positive or a negative electric charge depending on their state – that is, whether they carry electricity or don’t.

Those thousands of tiny little switches can either be on or off.

How Binary Works

You may have heard that ‘Computers work in 1s and 0s’ but what does that actually mean? We might not deal with binary code directly anymore, but it is the only thing that the computer's CPU understands.

Are there literally 0s and 1s stored in our physical devices flowing and moving around? Not really.

However, our CPU's consist of many microscopic digital circuits that carry information.

With the help of the transistors that come together to form these circuits and their tiny sequences of electrical signals that are switched either on ( 1 ) or off ( 0 ), there can only be only be two types of voltages – a high and a low. And that results in the representation of different values, that is different instructions or calculations being performed.

When these electrical signals from the transistor circuits and other electrical components are linked and combined/modified in a certain way, they can create a wide range of possible tasks and operations the computer can perform and see through.

Computers and Their Relationship with Humans

This machine-level programming language is the only language that computers can directly understand and are capable of making sense of.

The binary code can vary from computer to computer and from machine to machine. When it comes to this level of programming a computer, there is no portability. This means that programs and software can't be transferred to different systems.

Limitations of Machine Languages

Machine languages can vary depending on the operating system they are implemented on.

This is, of course, very limiting.

Machine code or binary code may run very fast, they may be the computer's native language, and they may be extremely efficient because the instructions are executed directly by the CPU. But it's a very dull and monotonous – not to mention extremely error-prone – way to use a computer.

Attempting to use a computer by manually typing binary codes for each transitor is a cumbersome process.

Making an error while directly managing the computer's data storage and operations is very hard to fix.

Machine-level languages are hard for humans to read, write, learn and understand. So programmers and computer scientists found a better and arguably easier way to solve problems.

The things a computer can do by itself are on a very primitive level and are limited in scope.

They are good at performing arithmetic calculations like adding numbers or checking if a number is equal to zero.

The Human Element in Computing

Humans created these machines that have revolutionized our way of life, but when it comes down to it, computers are really not that smart and have limited capabilities by themselves.

They only do exactly what they are told to do. They don’t make assumptions or have any common sense like humans do.

Computers at their core are machines that perform mathematical operations. But they are also good at displaying some text on the screen or repeating a task over and over again.

Those operations are basic and don’t go much further than that. They're known as the computer’s instruction set .

Even though at their core computers can only do very basic tasks, they are able to perform extremely complex actions and follow and execute instructions from programs they are given. This is thanks to the many layers of abstraction they have.

The true power however, lies in the hands of humans. Whatever we want to achieve and whatever we imagine, we can use this machine as a tool to do complicated calculations, conduct research to find and extract a document among billions of other documents, or keep in touch with friends and family far away.

Whatever we can think of, we can now create it by coding a program.

Computers and programs can improve our lives collectively all around the world. But how do we make them do what we want?

What is computer programming?

Computer coding and computer programming are terms that are often used interchangeably. They do have some differences though.

Programming vs coding

Programming means telling a computer what to do and how to do that thing you told it to do.

It involves providing well thought-out, methodogical instructions for your computer to read and execute.

You have to break down large tasks into smaller ones. And you keep repeating that process of breaking something down into smaller tasks until you reach a point where you don’t need to tell the computer what to do anymore – it already knows how to do that task.

The essence of programming is the process of problem solving, complex thinking, attention to detail, and reasoning – all using a computer.

Programming involves thinking of all the different steps a user could take and considering all the different things that could go wrong. Once you've thought of all potential problems a user may encounter you have to find solutions before you code anything.

We can think of problem solving as taking an input (the information and details about our problem that we want to solve) and generating an output (the end goal or the solution to our problem).

Outputs can be complicated and millions can run per second.

Problem Solving with Algorithms

When you're problem solving using a computer, you need to express the solution to that problem according to the instruction set of the computer.

For that purpose, we use algorithms – a systematic approach to solving problems.

Algorithms are an idea or method that's expressed in a very concise and precise set of rules and step by step instructions. The computer needs to follow these instructions in order to solve the problem.

When we think of algorithms, they don’t only apply to computers. They are also machine independent.

We humans follow algorithms too – sets of instructions for completing tasks in our daily lives.

Some examples could be:

  • counting people in a room
  • doing arithmetic calculations
  • trying to figure out the correct route to take to reach a particular destination
  • following a cooking recipe

In the last example, we can think of the recipe as the instructions that we use, and we're the computer that has to read and then execute them correctly.

An algorithm is a plan that presents the steps you need to follow in order to get a desired result.

How Computers Use Algorithms

When it comes to computers, algorithms need to be precise as computers take everything literally. They don’t read between the lines or make any assumptions.

There is no room for ambiguity, so algorithms not only need to be precise but also organized, correct, free from errors, efficient, and well-designed. All this helps minimize the time and effort the computer needs to spend to complete a task.

Computers execute algorithms in a mechanical way without putting much thought into each step. And they should work in the exact way we intended them to work.

A computer program is a collection of those instructions – or algorithms – in a text file which serves as an instruction manual.

It describes a very precise sequence of steps for the computer to follow. The computer performs a particular task, its hardrive executes the instructions, and you get the final desired result in the end.

Aside from the thinking, research, design, and in-depth planning, programming also involves testing, debugging, deployment, and maintanance of the finished result.

When you're developing a program to solve a particular problem, you typically express the idea for the solution using an algorithm. Then developers code the program by implementing that algorithm. You use a language that has particular syntax and that both humans and computers can understand.

This is where the actual coding comes in.

What is Computer Coding? A Simple Definition.

Coding is the process of transforming ideas, solutions, and instructions into the language that the computer can understand – that is, binary-machine code.

Coding is how humans are able to talk with computers.

Coding involves communicating and giving instructions for different actions we want our computers to perform using a computer programming language.

Programming languages , like JavaSctipt, Java, C/C++, or Python, act as the translator between humans and machines.

These languages bridge the communication gap between computers and humans by representing, expressing, and putting algorithms into practice. They do this using a specific sequence of statements that machines understand and can follow.

Programming languages are similar to human languages in the sense that they are made up of basic syntactical elements like nouns, verbs, and phrases. And you group these elements together to form something that resembles a sentence to create meaning.

These languages actually resemble and look a lot like English. But they offer a shorter, more precise and less verbose way to create instructions that the computer can understand.

A spoken/natural language like English, on the other hand, leaves a lot of room for ambiguity and different interpretations from different people.

Programming languages are a set of rules that define how you write computer code.

We use computer code to create all the web applications, websites, games, operating systems, and all the other software programs and technologies we use on a daily basis.

You can look at the code that makes up your favorite websites by hitting Control and clicking your touchpad/mouse then selecting View Page Source (or inspect ) from the menu that pops up (or you can use the shortcut Option Command U ):

Screenshot-2021-08-10-at-8.36.15-PM

You'll then see the HTML, CSS, and JavaScript that make up the frontend code of the website you're using:

Screenshot-2021-08-10-at-8.37.47-PM

In a nutshell, coding is the act of translating problems that are first in a natural, human language to a machine readable language. And that translation happens thanks to programming languages and coding.

Coding requires that you understand the intricacies, the particular syntax, and the specific keywords that make up a programming language. Once you know these features of a language, you can start developing applications.

In this article we learned how computers work at a high level. We then definied what programming is, what coding is, and the differences between them.

Remember that coding is only the process of writing code to develop programs and applications.

Coding is a subset of programming, which entails the logical reasoning, analysis, and planning out a sequence of instructions for a computer program or application before any coding is done.

Programming is the bigger picture in the process. Coding is a part of that process, but should always come after the programming, or problem-solving and planning stage.

I hoped this helped you understsand programming and coding basics. Thanks for reading!

Title: looking ahead to avoid being late: solving hard-constrained traveling salesman problem.

Abstract: Many real-world problems can be formulated as a constrained Traveling Salesman Problem (TSP). However, the constraints are always complex and numerous, making the TSPs challenging to solve. When the number of complicated constraints grows, it is time-consuming for traditional heuristic algorithms to avoid illegitimate outcomes. Learning-based methods provide an alternative to solve TSPs in a soft manner, which also supports GPU acceleration to generate solutions quickly. Nevertheless, the soft manner inevitably results in difficulty solving hard-constrained problems with learning algorithms, and the conflicts between legality and optimality may substantially affect the optimality of the solution. To overcome this problem and to have an effective solution against hard constraints, we proposed a novel learning-based method that uses looking-ahead information as the feature to improve the legality of TSP with Time Windows (TSPTW) solutions. Besides, we constructed TSPTW datasets with hard constraints in order to accurately evaluate and benchmark the statistical performance of various approaches, which can serve the community for future research. With comprehensive experiments on diverse datasets, MUSLA outperforms existing baselines and shows generalizability potential.
