The Burrows–Wheeler transform is an algorithmused to prepare data for use with data compressiontechniques such as bzip2. It was invented by Michael Burrowsand David Wheelerin 1994 while Burrows was working at DEC Systems Research Centerin Palo Alto, California. It is based on a previously … See more The Burrows–Wheeler transform (BWT, also called block-sorting compression) rearranges a character string into runs of similar characters. This is useful for compression, since it tends to be easy to compress a string … See more To understand why this creates more-easily-compressible data, consider transforming a long English text frequently containing the word "the". Sorting the rotations of this text will group rotations starting with "he " together, and the last character of that … See more Since any rotation of the input string will lead to the same transformed string, the BWT cannot be inverted without adding an EOF marker to the … See more When a character string is transformed by the BWT, the transformation permutes the order of the characters.
