grzipii

GRZipII - is a high-performance file compressor based on Burrows-Wheeler Transform, Schindler Transform, Move-To-Front and Weighted Frequency Counting. It uses The Block-Sorting Lossless Data Compression Algorithm, which has received considerable attention over recent years for both its simplicity and effectiveness. This implementation has compression rate of 2.234 bps on the Calgary Corpus(14 files) without preprocessing filters.
