AQA 7517 4.4.1.8: Problem abstraction/reduction

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

1. A2.4 Abstraction and models Recursion and computational thinking
   Representational abstraction, generalisation, problem reduction, and a grid model of the mat that differs from reality.
2. A2.9 Computational methods Recursion and computational thinking
   Problem recognition, divide and conquer, backtracking, heuristics, performance modelling, data mining and visualisation.
