Results will be added to Max compression site this weekend.
News about TC development:
+ I've made a lots of experiments with various SEE (secondary escape estimation) implementations. Nothing works. Its due to current escape method is not the pure PPMC, it represents semi-adaptive method related to PPMC, wich works very well.
+ I think I must add the full exclusions mechanism to current PPM. This gives noticeable compression improvement in cost of speed. My current implementation of full exclusions is dead slow. If I implement something more efficient, and speed will be affected not too much I release a new version! Okay, what about compression power, I like the results with the full exclusion mechanism, especially compression improved on binary files, on text files compression is also improved, but not so much.
