Authors: Marvin Künnemann. … WebMay 30, 2024 · Here we extend Freivalds’ algorithm to a Gaussian Variant of Freivalds’ Algorithm (GVFA) by projecting the product A × B A\times B as well as 𝐶 onto a Gaussian random vector and then comparing the resulting vectors. The computational complexity of GVFA is consistent with that of Freivalds’ algorithm, which is O ( n 2 ) O(n^{2}) .

His C cows don't like this barn layout and become aggressive towards each other once put into a stall. To prevent the cows from hurting each other, John wants to assign the cows to ... 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). This beats the classical deterministic algorithm's runtime of $${\displaystyle O(n^{3})}$$ (or Freivalds' algorithm … See more
