SALZA is an implementation of algorithmic information theory based on LZ77 and relative LZ coding, a universal semi-distance on strings, and a implementation of the PC algorithm for causality inference.

DRPT allows to transform a semi-distance matrix into a distance matrix.

CSA is a compressed self-index with limited archiving capabilities. A compressed self-index supports counting and locating queries on a compressed representation of the text, as well as decompression of an arbitrary substring.

OOPZIP is a tutorial implementation of gzip/DEFLATE.
