the program website March 28, 2009Blizzard is a fast BWT file compressor using ~6N memory (5N is easily possible, though). It uses an executable data filter and processes the transformed data with a simple context mixer.
Blizzard has two modes of compression: a fast mode 'f' and a normal mode 'c'. The fast mode uses a simpler context mixer which provides a little bit less compression. Blizzard's main goal is to provide good (not best) BWT-compression at a reasonable speed in one single package.
The compressor is featured in the BWT comparison.
