Re-pair Achieves High-Order Entropy. Abstract: Re-pair is a dictionary-based compression method invented in 1999 by J. Larsson and A. Moffat [Off-line ...
In this paper we show that Re-Pair compresses a sequence T[1,n] over an alphabet of size σ and k-th order entropy Hk, to at most 2Hk +o(nlog σ) bits, for any k ...
Re-Pair repeatedly finds the most frequent pair ab of symbols in the sequence and replaces its occurrences by a new symbol A, adding a rule A → ab to a ...

Despite its simplicity, Re-Pair achieves high-order entropy compression [12] and-especially on repetitive datasets-is an excellent compressor in practice [8,10, ...
