7-Zip uses the Lempel-Ziv-Markov chain algorithm. You can find the technical specifications and source code in the LZMA SDK. đź“š Academic & Comparative Papers
Research often focuses on "Lossless Data Compression Algorithms." A common reference is the paper “A Comparative Study of Lossless Data Compression Algorithms” , which analyzes LZMA’s efficiency against others. 7-Zip uses the Lempel-Ziv-Markov chain algorithm
For a deeper look into the math behind the compression used in 7-Zip, search for papers on “Lempel-Ziv-Markov chain algorithm performance” on Google Scholar. For a deeper look into the math behind
The best starting point for understanding its architecture and command-line usage is on the 7-Zip Official Site . which analyzes LZMA’s efficiency against others.
