m03

M03 is a full order context based compression algorithm for the Burrows/Wheeler Transform. This alpha release uses approximately 6N for encoding and 5N for decoding. Compression ratios and encode/decode speeds are very competitive however this release is just the most basic form of the algorithm and there is still a lot of room for improvements on speed, memory and compression.

It uses no preprocessing or filters. Simply BWT and direct encoding of the BWT.
