WebJul 14, 2024 · Strassen’s Algorithm. Strassen’s algorithm makes use of the same divide and conquer approach as above, but instead uses only 7 recursive calls rather than 8 as shown in the equations below. Here we save one recursive call, but have several new additions of n/2 x n/2 matrices. M 1 = (A11 +A22)(B11 +B22) M 1 = ( A 11 + A 22) ( B 11 + B 22) M ...

WebThe basic idea of Strassen's factorization method is that if you have the product f i of a consecutive set of integers modulo the number to be factored n, and that set of integers contains one the factors of n, then g c d ( f i, n) will be greater than unity. The trick then is to compute f i for non-overlapping sets of possible factors quickly.
