WebJan 7, 2016 · The Burrows-Wheeler Transform, or BWT, transforms a block of data into a format that is extremely well suited for compression. The BWT is an algorithm that takes a block of data and rearranges it using a sorting algorithm. The transformation is reversible, meaning the original ordering of the data elements can be restored with no loss of ... WebThe BWT is thus a "free" method of improving the efficiency of text compression algorithms, costing only some extra computation.
