We apply results on extracting randomness from independent sources to “extract” Kolmogorov complexity. For any α,ϵ>0, given a string x with K(x)>α|x|, we show how to use a constant number of advice bits to efficiently compute another string y, |y|=Ω(|x|), with K(y)>(1-ϵ)|y|. This result holds for both unbounded and space-bounded Kolmogorov complexity.We use the extraction procedure for space-bounded complexity to establish zero-one laws for the strong dimensions of complexity classes within ESPACE. The unbounded extraction procedure yields a
zero-one law
for the constructive strong dimensions of Turing degrees.
