Dynamic Programming The method of dynamic programming is analagous, but different from optimal control in that optimal control uses continuous time while dynamic programming uses discrete time.

Dynamic programming has enabled economists to formulate and solve a huge variety of problems involving sequential decision making under uncertainty, and as a result it is now widely regarded as the single most important tool in economics. It gives us the tools and techniques to analyse (usually numerically but often analytically) a whole class of models in which the problems faced by economic agents have a recursive nature. on economic growth, but includes two very nice chapters on dynamic programming and optimal control.
