The randomness rate of an infinite binary sequence is characterized by the sequence of ratios between the Kolmogorov complexity and the length of the initial segments of the sequence. It is known that there is no effective procedure that transforms one input sequence into another sequence with higher randomness rate. By contrast, we display such a uniform effective procedure having as input two independent sequences with positive but arbitrarily small constant randomness rate. Moreover the… Expand

It is shown that a computable function is an almost randomness extractor if and only if it is a Kolmogorov complexity extractor, thus establishing a fundamental equivalence between two forms of extraction studied in the literature: Kolmogsorov extraction and randomness extraction. Expand

It is shown that the answer to Jan Reimann's question whether there is a Turing cone of broken dimension is affirmative if Hausdorff dimension is replaced by its inner analogue packing dimension, and a minimal degree of effective packing dimension is constructed. Expand

The Kučera-Gács theorem is examined from the perspective of decompression, by showing that every infinite sequence S is Turing reducible to a Martin-Löf random sequence R such that the asymptotic number of bits of R needed to compute n bits of S, divided by n, is precisely the constructive dimension of S, which is shown to be the optimal ratio of query bits to computed bits achievable with Turing reductions.
