Analysis of information sources in references of the Wikipedia article "Lempel–Ziv–Markov chain algorithm" in English language version.
LZHAM is a lossless data compression codec written in C/C++ with a compression ratio similar to LZMA but with 1.5–8 times faster decompression speed.
LZMA2 is a modified version of LZMA that offers a better compression ratio for uncompressible data (random data expands about 0.005%, compared to 1.35% with original LZMA), and optionally can compress multiple parts of large files in parallel, greatly increasing compression speed but with a possible reduction in compression ratio.
