Study Notes
Overview of Computing Concepts
- Core concepts include problem identification, types of problems (routine vs. non-routine), and problem-solving methods.
- Introduction to algorithms and heuristics as foundational techniques for solving computing problems.
- Distinction between solvable and unsolvable problems.
- Various solution techniques: abstraction, analogy, brainstorming, trial and error, hypothesis testing, reduction, literal thinking, means-end analysis, method of focal object, morphological analysis, research, root cause analysis, proof, and divide and conquer.
- General problem-solving process and methods for solution formulation and design, including flowcharts, pseudocode, decision tables, and decision trees.
- Programming in languages such as C++ and Python is emphasized.
