Matrix chain multiplication (or the matrix chain ordering problem ) is an optimization problem concerning the most efficient way to multiply a given sequence of matrices. The problem is not actually to perform the multiplications, but merely to decide the sequence of the matrix multiplications involved. The problem may … See more To begin, let us assume that all we really want to know is the minimum cost, or minimum number of arithmetic operations needed to multiply out the matrices. If we are only multiplying two matrices, there is only one way to … See more There are algorithms that are more efficient than the O(n ) dynamic programming algorithm, though they are more complex.
