In probabilistic computations, random bits are viewed as a resource. An important goal is to consume as little of it as possible. We study functions, which decrease the number of random bits needed by an algorithms. Loss-less condensers take as input a low entropy source, and output a source, which is statistically close to a high entropy source. This closeness is referred to as the error of th...
