WebChained Matrix Multiplication. Problem: Given a series of n arrays (of appropriate sizes) to multiply: A 1 × A 2 × ⋯ × A n. Determine where to place parentheses to minimize the number of multiplications. Multiplying an i × j array with a j × k array takes i × j × k array. Matrix multiplication is associative, so all placements give ... WebNotice that our chain matrix multiplication problem satis es the principle of optimality. In particular, once we decide to break the sequence into the product A 1::k A k+1::n, it is in our best interest to compute each subsequence optimally. That is, for the global problem to be solved optimally, the subproblems should be solved optimally as well.
Web2 Answers Sorted by: 11 The final solution is to calculate m [0,N]. But all m [i,j] values need to be calculated before m [0,N] can be calculated. This makes it O (N^2). From the recursion formula you can see each m [i,j] calculation needs O (N) complexity. So O (N^3) for the complete solution.

It’s much faster and better if we multiply XY first, then multiply the final result by Z. Multiplying the first two matrices first (on the left) creates a small matrix, which allows for faster calculation. softio ltd
