Dynamic programming is a very important algorithm design idea. Historically there have been many well-known algorithms based on this idea, such as: Needleman–wunsch algorithm, CYK algorithm, FFT algorithm, Viterbi algorithm and so on. There are two core ideas in dynamic programming: First, to disassemble a large problem into several sub problems, and then to store the results that have been calculated for multiple use.
Dynamic planning is important because it is a frequent focus of written inte
