AQA 7517 4.4.4.3: Order of complexity
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
- A5.2 Big O notation Algorithms and complexity
Dominant terms, the orders of complexity from O(1) to O(2^n), deriving complexity from code, best, average and worst case, and space… - A5.9 Project: plan the route, then drive it Algorithms and complexity
Choose and justify a route planner, build the mat's graph, find the shortest route with Dijkstra's algorithm and drive it. - A15.7 Calculation and theory questions Exam preparation
Number representation, floating point, Boolean logic, state machines and complexity answered quickly and checked.
