OCR H446 2.2.2: Computational methods
The free BugBot lessons that teach this point, a robot to try it on, and the past-paper questions that test it.
Lessons that teach it
- A2.6 Decomposition, composition and automation Recursion and computational thinking
Thinking procedurally, compound procedures and compound data, and putting a model into action. - A2.8 Thinking concurrently Recursion and computational thinking
Concurrent and parallel processing, what can happen at once, benefits and trade-offs, and pipelining. - A2.9 Computational methods Recursion and computational thinking
Problem recognition, divide and conquer, backtracking, heuristics, performance modelling, data mining and visualisation. - A2.10 Project: out of the dead end Recursion and computational thinking
Model a maze, solve it by recursive backtracking, and drive the robot out along the route.
