Abstract

Given a randomized algorithm A, a natural approach towards derandomizing it is to find a method for searching the associated sample space Ω for a good point ω with respect to a given input instance x; a point is good for x if A(x, ω) = f(x). Given such a point ω, the algorithm A(x,ω) becomes a deterministic algorithm and it is guaranteed to find the correct solution. The problem faced in searching the sample space is that it is usually exponential in size.
