http://staff.ustc.edu.cn/~csli/graduate/algorithms/book6/chap16.htm WebMemoization is a set of dynamic programming and recursion. The technique is in the top-down direction, where all solutions are stored in the memory. This technique does not solve the same problem many times; it uses the previously calculated solutions to find the solution to the general problem. The dynamic matrix initially denoted with 0.

WebMatrix Chain Multiplication (or Matrix Chain Ordering Problem,MCOP) is an optimization problem that can be solved using dynamic programming. MCOP helps to find the most efficient way to multiply matrices. Solution for the matrix chain multiplication problem is Strassen’s Matrix Multiplication.
