Optimal parenthesization of matrix

WebIn parenthesizing the expression, we can consider the highest level of At this level we are simply multiplying two matrices together. That is, for any k, 1 ≤ k≤ n− 1, A1..n=A1..k Ak+1..n. Therefore, the problem of determining the optimal sequence of multiplications is broken up into two questions: WebStep 1: Determine the structure of an optimal solution (in this case, a parenthesization). Decompose the problem into subproblems: For each pair , determine the multiplication sequence for that minimizes the number of multiplications. Clearly, is a matrix. Original Problem: determine sequence of multiplica-tion for . 8
