1.	Strassen’s algorithm is quite numerically stable as the naïve method.(a) True(b) FalseThis question was addressed to me during an interview.This is a very interesting question from Number Theory in chapter Number Theory of Data Structures & Algorithms II
Answer» Right answer is (b) False Easiest explanation - Strassen’s ALGORITHM is too numerically UNSTABLE for some applications.The computed result C=AB satisfies the INEQUALITY with a unit ROUNDOFF error which corresponds to strong STABILITY inequality(obtained by replacing matrix norms with absolute values of the matrix elements).
