WebMar 8, 2024 · The algorithm keeps track of its random guesses as entries in a matrix. Finding the solution among the entries in the matrix becomes a question of matrix multiplication, which of course is the roadblock they’d set out to circumvent. But here again they take advantage of the randomness that they used to seed the entries in the matrix. In linear algebra, the Strassen algorithm, named after Volker Strassen, is an algorithm for matrix multiplication. It is faster than the standard matrix multiplication algorithm for large matrices, with a better asymptotic complexity, although the naive algorithm is often better for smaller matrices. The Strassen algorithm is slower than the fastest known algorithms for extremely large matrices, but such galactic algorithms are not useful in practice, as they are much slower for matrices of pr…
