Webruns in time O(n3) and then show how we can do better using Strassen’s Algorithm. We will only consider dense matrix multiplication, in which most of the entries of the input matrices are nonzero. For sparse matrices, in which most of the entries are 0, there are algorithms for matrix multiplication that leverage this sparsity to get a better ... WebWhile the classical algorithms for matrix multiplication are already optimized for reducing communication cost to the minimum possible, a completely di erent algorithmic approach for this problem is possible. Let us recall Strassen’s algorithm [24] (see Algorithm 3). Strassen’s key idea is to multiply 2 2 matrices using 7
