Matrix chain multiplication: We have six matrices, A1, A2, A3, A4, A5 and A6. The dimensions are respectively (10,30), (30,60), (60,10), (10,30), (30,40) and (40,10). A1..6 = A1A2A3A4A5 A6. Using dynamic programming, we can find the best way (that minimize the number of scalar multiplications) to compute the product A1.6. Let m[i, j] denote the minimum number of scalar multiplications to compute A;A;+1 ... Aj. Compute m[1, 4] and fully parenthesize the matrices A1 A2 A3 A4 so that the optimal solutions are obtained.
