Experimental Evaluation of List Update Algorithms for Data Compression
List update algorithms have been widely used as subroutines in compression schemas, most notably as part of Burrows-Wheeler compression. The Burrows-Wheeler transform (BWT), which is the basis of many state-of-the-art general purpose compressors applies a compression algorithm to a permuted version of the original text. List update algorithms are a common choice for this second stage of BWT-bas...

متن کاملOne attempt of a compression algorithm using the BWT
In 1994 Burrows and Wheeler [5] described a universal data compression algorithm (BW-algorithm, for short) which achieved compression rates that were close to the best known compression rates. Due to it’s simplicity, the algorithm can be implemented with relatively low complexity. Fenwick [8] described ideas to improve the efficiency (i.e. the compression rate) and complexity of the BW-algorith...
متن کاملError-Resilient Block Sorting
“Blocksorting Transform” (BWT) is a lossless compression technique that has become increasingly popular in recent years due to the fact that it achieves high performance compression (almost as good as in PPM, with fast speed (not much slower than gZip). It is perhaps the first lossless compression algorithm to combine these two properties. BWT breaks its input into large blocks, and performs an...
متن کاملUniversal Lossless Source Coding with the Burrows Wheeler Transform
The Burrows Wheeler Transform (BWT) is a reversible sequence transformation used in a variety of practical lossless source-coding algorithms. In each, the BWT is followed by a lossless source code that attempts to exploit the natural ordering of the BWT coefficients. BWT-based compression schemes are widely touted as low-complexity algorithms giving lossless coding rates better than those of th...
