Study Notes
Decomposition (Divide and Conquer)
- Break complex problems into smaller, manageable sub-problems
- Solve sub-problems individually and combine for a final solution
- Used in algorithm design (e.g., Merge Sort)
Algorithmic Thinking
- Develop step-by-step procedure (algorithm) to solve problems
- Define clear instructions for desired outcome
- Automate repetitive tasks using loops, recursion
Abstraction
- Focus on high-level structure of problem, ignoring unnecessary details
- Identify core components and relationships to simplify the problem
- Used in object-oriented programming (OOP) to create classes that represent real-world entities
Pattern Recognition
- Identify patterns or similarities between problems
- Use known solutions to tackle new problems
- Recognize common design patterns like Singleton or Observer for efficient code structuring
Incremental Development
- Build and test solutions incrementally
- Start with the simplest version, gradually adding complexity
- Allows for easier identification of issues
- Used in agile software development (MVP)
Debugging and Testing
- Systematically identify and fix errors in the code.
- Use debugging tools and unit tests to find and resolve issues
- Examples: Breakpoints, log statements, and IDEs like Visual Studio or Pycharm
Optimization
- Make solutions more efficient in time and space
- Improve performance, especially with large datasets
- Use techniques like memorization in dynamic programming or efficient data structures (e.g., hash tables, binary search trees)
Backtracking
- Try different approaches to solve problems
- Backtrack (undo last step) when you hit a dead end
- Used in solving puzzles like the N-Queens problem or finding combinations in a set
Simulation and Modeling
- Simulate environments or create models
- Understand system behavior under various conditions
- Predict outcomes and plan solutions
- Used in game development or AI programming to simulate player behavior, optimize strategies, or predict outcomes
Collaborative Problem Solving
- Work in teams to solve problems
- Different perspectives can lead to innovative solutions
- Pair programming helps find and fix issues
- Example: Pair programming in software development where two programmers work together on the same codebase
