WebWe now need to figure out when Strassen begins to have a lower cost than the normal matrix multiplication algorithm. To find this we can look at the crossover point where Strassen switches to regular matrix multiplication. We need to look at: 2n^3 − n^2 = 7(2(n/2)^3 − (n/2)^2) + 18(n/2)^2. This gives us n0 = 15, or cp = 15. WebA variant of Strassen’s sequential algorithm was developed by Coppersmith and Winograd, they achieved a run time of O(n2:375).[3] The current best algorithm for matrix multiplication O(n2:373) was developed by Stanford’s own Virginia Williams[5].
