YBS (blocksorting compressor)

YBS is a high-performance archiver based on Burrows-Wheeler Transform and distance coding modelling. It's quite fast even on skew data and achives high compression ratio.

  • DOS version (60kB)
  • Win-32 version (43kB)
    •  22.09.2002: version 0.03f. I remember my compressor :)
    - fixed bug appearing while compressing with maximum block size 16Mb (thanks to Sebastian and Szymon).
    - compression ratio is slightly improved

    25.09.2000: version 0.03e
    - fixed DJGPP 2.01 memory allocation bug in DOS version
    - improved sorting of files like kennedy.xls

    Thanks to
    Edgar Binder - for describing me distance coding algorithm,
    Szymon Grabowski - for text tricks (I don't implemented yet :) and testing,
    Aleksandr Ratushnyak, Dmitry Shkarin, Eugene Shelwien, Sebastian Deorowicz, Vladimir Trutnev - for testing.

    I'll be appreciative for suggestions and bug reports.
