http://www.cs.fit.edu/~mmahoney/compression/ says: PAQ4 Archiver PAQ4 mixes models using adaptive rather than fixed weights, and also includes an improved model for data with fixed length records. This is all explained in the source code. paq4.cpp Source code (Oct. 16, 2003) The reason I bring this attention to the ppmd package maintainer is that it seems that for at least some files, the PAQ line gives better results than ppmd, ppmonster... In fact it seems that PAQ4 may have done better on compression the Calgary Corpus than any other open source compressor. I haven't looked into the algorithms and some testing may be needed anyway to see whether this could be a valuable (more than ppmd) contribution to Debian. Drew Daniels
