# Fastest Matrix Multiply Algorithm

**Mathematics Accomplishment |** **1990**

** IBM researchers: **Don Coppersmith, Shmuel Winograd

**Where the work was done**: IBM T.J. Watson Research Center

**What we accomplished**: Also known as Fast Matrix Multiply, the Coppersmith-Winograd Algorithm was the asymptotically fastest known algorithm for square matrix multiplication until 2010 when improved variants of Coppersmith-Winograd surfaced.
