Abstract

New mechanism for PPM data compression scheme is invented. Simple procedures for adaptive escape estimation are proposed. Practical implementation of these methods is described and showed that this implementation gives best to date results at complexity comparable with widespread LZ77- and BWT-based algorithms.
