This is a Python program to solve matrix-chain multiplication using dynamic programming with bottom-up approach. Problem Description In the matrix-chain multiplication problem, we are given a sequence of matrices A(1), A(2), …, A(n). The aim is to compute the product A(1)…A(n) with the minimum number of scalar multiplications. Thus, we have to find an optimal … Read more
