WebThe Burrows and Wheeler transform (BWT) is a block sorting lossless and reversible data transform. The BWT can permute a text into a new sequence which is usually more compressible. Surfaced not long ago, 1994, by Michael Burrows and David Wheeler.

WebBurrows can be up to 40 feet (12 meters) in length and 10 feet (3 meters) in depth. Each burrow has a single opening and the width of the burrow is approximately equal to the length of the tortoise. WebMar 5, 2013 · The Burrows–Wheeler transform (BWT) is a method for permuting a list with the aim of bringing repeated elements together. Its main use is as a preprocessing step in data compression. Lists with many repeated adjacent elements can be encoded compactly using simple schemes such as run length or move-to-front encoding.
