WebNov 1, 2010 · The Burrows–Wheeler Transform is an efficient data compression algorithm, which recently gains an increasing interest in the aspect of applications in genomics [21]. Our algorithm allows for listing all occurrences of exact tandem repeats in a given string of length n in O (n log n) time. WebApr 6, 2024 · The Burrows-Wheeler Transform (BWT) has become since its introduction a key tool for representing large text collections in compressed space while supporting … 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 that has runs of repeated characters by techniques such as move-to-front transform and run-length encoding. More importantly, the transformation is reversible, without needing to store any additional data except the position of the first original character.
