Yes, he is the man who changed the Matrix Multiplication game just like Einstein changed the Gravity game. Der Strassen-Algorithmus (erfunden vom deutschen Mathematiker Volker Strassen) ist ein Algorithmus aus der Linearen Algebra und wird zur Matrizenmultiplikation verwendet. Der Strassen-Algorithmus realisiert die Matrizenmultiplikation asymptotisch effizienter als das Standardverfahren und ist in der Praxis schneller für große Matrizen (solche mit einem Rang größer als 1000). 2021-01-28 · Volker Strassen’s is a name who published his algorithm to prove that the time complexity O(n 3) of general matrix multiplication wasn’t optimal.So it was published Strassen’s matrix chain multiplication and reduced the time complexity. 2008-12-11 · The Strassen algorithm replaces multiplies with additions. At one time computer additions were quicker than multiplies. No longer true since floating point processors.

Divide X, Y and Z into four (n/2)× (n/2) matrices as represented below − Z = [ I J K L] X = [A B C D] and Y = [E F G H] review Strassen’s sequential algorithm for matrix multiplication which requires O(nlog 2 7) = O(n2:81) operations; the algorithm is amenable to parallelizable.[4] A variant of Strassen’s sequential algorithm was developed by Coppersmith and Winograd, they achieved a run time of O(n2:375).[3] In general, multipling two matrices of size N X N takes N^3 operations. Since then, we have come a long way to better and clever matrix multiplication algorithms. Volker Strassen first published his algorithm in 1969.

1997-07-13 · Strassen's algorithm for matrix multiplication gains its lower arithmetic complexity at the expense of reduced locality of reference, which makes it challenging to implement the algorithm efficiently on a modern machine with a hierarchical memory system.

However, let’s get again on what’s behind the divide and conquer approach and implement it. Prerequisite: It is required to see this post before further understanding.

Strassen’s Matrix multiplication can be performed only on square matrices where n is a power of 2. Order of both of the matrices are n × n. Divide X, Y and Z into four (n/2)× (n/2) matrices as represented below − Z = [ I J K L] X = [A B C D] and Y = [E F G H]

We have discussed Strassen’s Algorithm here. However, let’s get again on what’s behind the divide and conquer approach and implement it.
