math, logic, dynamic programming

dynamic programming

• take a recursive algorithm and cache overlapping problems (repeated calls).
• the runtime is given by the number of calls.
• top-down: how can we divide the problem into sub-problems?
  • top-down dynamic programming is called memoization.
• bottom-up: solve for a simple case, then figure out for more elements.
