Data compression - Wikipedia, the free encyclopedia
In computer science and information theory, data compression or source coding is the process of encoding information using fewer bits (or other information-bearing units) than an unencoded represe...

Lossless data compression - Wikipedia, the free encyclopedia
Lossless data compression is a class of data compression algorithms that allows the exact original data to be reconstructed from the compressed data. The term lossless is in contrast to lossy data ...

p5 uses 1 MB memory and context orders 0 to 3. p6 uses 16 MB and orders 0-5. p12 uses 16 MB, orders 1-4 and word-level orders 0-1 as an optimization for text. The programs take no options. The algorithm is described in M. Mahoney, Fast Text Compression with Neural Networks, Proc.

This report presents some further work on the recently described “Block Sorting” lossless or text compression algorithm. It is already known that it is a context-based compressor of unbounded order, but those contexts are completely restructured by the sort phase of the compression.
