What is meant by step-wise refinement in problem-solving?

Step-wise refinement is a problem-solving technique where a complex problem is systematically broken down into smaller, more manageable components or sub-problems. This approach allows for a clearer understanding of each part of the problem, making it easier to develop specific solutions for each component.

By dividing the problem into smaller steps, it becomes possible to tackle each part individually, which often leads to more efficient and effective problem-solving. Each smaller component can be refined and developed further, allowing you to build a comprehensive solution step by step. This method is particularly useful in software design and development, as it aligns with the structured approach needed for coding and algorithm creation.

Choosing to break down the problem facilitates better focus on individual aspects, reducing complexity and enhancing clarity throughout the process. This technique contrasts with parallel problem-solving, where multiple solutions are sought simultaneously, or applying uniform solutions across different problems without addressing specific context or variability.
