WebIn this article, we consider the general problem of checking the correctness of matrix multiplication. Given three n×nn\\times n matrices 𝐴, 𝐵 and 𝐶, the goal is to verify that A×B=CA\\times B=C without carrying out the computationally costly operations of matrix multiplication and comparing the product A×BA\\times B with 𝐶, term by term. This is … Freivalds' algorithm (named after Rūsiņš Mārtiņš Freivalds) is a probabilistic randomized algorithm used to verify matrix multiplication. Given three n × n matrices $${\displaystyle A}$$, $${\displaystyle B}$$, and $${\displaystyle C}$$, a general problem is to verify whether See more Suppose one wished to determine whether: A random two-element vector with entries equal to 0 or 1 is selected – say See more • Schwartz–Zippel lemma See more Let p equal the probability of error. We claim that if A × B = C, then p = 0, and if A × B ≠ C, then p ≤ 1/2. Case A × B = C See more Simple algorithmic analysis shows that the running time of this algorithm is $${\displaystyle O(n^{2})}$$ (in big O notation).
