The Burrows–Wheeler transform is an algorithm used to prepare data for use with data compression techniques such as bzip2. It was invented by Michael Burrows and David Wheeler in 1994 while Burrows was working at DEC Systems Research Center in Palo Alto , California. 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 The transform is done by sorting all the circular shifts of a text in lexicographic order and by extracting the last column and the index of the original … See more A number of optimizations can make these algorithms run more efficiently without changing the output. There is no need to represent the table … See more When a text is edited, its Burrows–Wheeler transform will change. Salson et al. propose an algorithm that deduces the Burrows–Wheeler transform of an edited text … See more When a character string is transformed by the BWT, the transformation permutes the order of the characters. If the original string had several substrings that occurred often, then the transformed string will have several places where a single character is repeated multiple … 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 end of the input or doing something … See more
