WebAssume we have three matrices A 10 x 100, B 100 x 5, C 5 x 50. The costs for the two different parenthesizations are as follows: cost( (AB)C) = 10*100*5 + 10*5*50 = 5000 + 2500 = 7500 cost(A(BC)) = 10*100*50 + 100*5*50 = 50000 + 25000 = 75000 References [ 1] Cormen, “Introduction to Algorithms”, Chapter 15.2, p. 370-378 [ 2]
