an algorithm based on Lempel-Ziv algorithm
LZMA, short for Lempel-Ziv-Markov chain-Algorithm, is a data compression algorithm in development since 1998 and used in the 7z format of the 7-Zip archiver. It uses a dictionary compression scheme somewhat similar to LZ77 and features a high compression ratio (generally higher than bzip2) and a variable compression-dictionary size (up to 1 GB).
