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.

The author comments that the program uses no preprocessing.

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