Burrow-length transform
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.
