Freivalds' algorithm
text:
Freivalds' algorithm is a probabilistic randomized algorithm used to verify matrix multiplication. Given three n × n matrices A , B , and C , a general problem is to verify whether A × B = C . A naïve algorithm would compute the product A × B explicitly and compare term by term whether this product equals C . However, the best known matrix multiplication algorithm runs in O time. Freivalds' algorithm utilizes randomization in order to reduce this time bound to O with high probability. In O time
