Experimental lossless data compressor
Original language description
x3 is a lossless optimizing dictionary-based data compressor. The algorithm uses a combination of a dictionary, context modeling, and arithmetic coding. Optimization adds the ability to find the most appropriate parameters for each file. Even without optimization, x3 can compress data with a compression ratio comparable to the best dictionary compression methods like LZMA, zstd, or Brotli. Our work differs from others by explicitly inserting phrases into the dictionary. This is a gap not yet covered by any other compression method.
