bwtmix

The author describes the program in the following way:

BWTmix is a simple integrated demo for http://ctxmodel.net/files/mix_test/mix_test_v8.rar with an inefficient generic qsort-based BWT. And mix_test itself is an experiment on evaluation/improvement of logistic mixer (aka paq mixer).

BWTmix 1s was sent by David Scott. It is BWTmix 1 compiled with OpenBWT to replace the qsort-based BWT with BWTS transform. OpenBWT is an open source library by Yuta Mori that includes linear-time BWT and BWTS, the inverse transforms and several second stage algorithms for BWT-based compression.

The compressor is featured in the BWT comparison.
