Dynamic Programming is mainly an optimization over plain recursion. When the state-space is large, it can be combined with a function approximation scheme such as regression or a neural network algorithm to approximate the value function of dynamic programming, thereby generating a solution. Wherever we see a recursive solution that has repeated calls for same inputs, we can optimize it using Dynamic Programming. The method was developed by Richard Bellman in the 1950s and has found applications in numerous fields, from aerospace engineering to economics..
