WebThe Burrows–Wheeler transform block sorting algorithm used in bzip2 is limited to 900 KiB of history. The history buffer in rzip can be up to 900 MiB long, several orders of magnitude larger than gzip or bzip2. Rzip is often much faster than bzip2, despite using the bzip2 library as a back end. WebWe describe a block-sorting,losslessdata compression algorithm, and our imple-mentation of that algorithm. We compare the performance of our implementation …

WebJan 6, 2024 · bzip2 is a free and open-source file compression program that uses the Burrows–Wheeler algorithm. It only compresses single files and is not a file archiver. It is developed and maintained by Julian Seward. Seward made the first public release of bzip2, version 0.15, in July 1996. WebJul 13, 2024 · We propose a novel compression algorithm, CoMSA, designed especially for aligned data. It is based on a generalization of the positional Burrows–Wheeler transform for non-binary alphabets. CoMSA handles FASTA, as well as Stockholm files.
