Study Notes

Problem Solving Phases

Children’s ages example illustrates how multi-phase problem solving allows concluding incorrect assumptions.
Understanding the problem can evolve through experimenting with solving strategies.
Four phases of problem-solving defined by G. Polya:
- Phase 1: Understand the problem.
- Phase 2: Devise a plan for solving the problem.
- Phase 3: Carry out the plan.
- Phase 4: Evaluate the solution's accuracy and broader applicability.

Algorithm and Problem-Solving Approaches

Problem-solving techniques are essential across various fields, not limited to computer science.
No single algorithm can encapsulate the entire problem-solving process due to its artistic and elusive nature.
"Getting your foot in the door" is a common theme in problem-solving strategies, emphasizing initial engagement with the challenge.

Discovery Strategies

The initial steps in discovering an algorithm involve understanding the problem before formulating a solution.
Special cases can serve as a starting point for developing a general algorithm through related problem solving.

Stepwise Refinement Methodology

Stepwise refinement advocates breaking down a complex problem into manageable subproblems.
This technique entails viewing the problem from a broad perspective and drilling down to specifics, resembling a top-down approach.
Alternatively, a bottom-up methodology begins with small, specific elements and works toward a comprehensive solution.
Both methodologies complement each other and utilize the problem solver’s intuition to effectively decompose issues.
