BWT: The Burrows-Wheeler Transform

Data Compression at Your Fingertips

Unlocking the Power of Data Compression

The Burrows-Wheeler Transform (BWT) is a revolutionary algorithm that has taken the world of data compression by storm. It restructures data in a way that makes it ideal for further compression by techniques like bzip2.

The Essence of BWT

The BWT is a text transform that rearranges the characters of a string, creating a new string (BWTT) with unique properties. This transformation provides significant benefits for data compression and search algorithms.

Example in Action

For instance, consider the word "banana". Applying the BWT would yield the following BWTT: "nanaba". This transformation highlights repeating patterns and enhances the compressibility of the original string.

Innovation in Data Compression

The advent of the BWT has revolutionized data compression. By paving the way for highly efficient algorithms, the BWT has enabled us to store and transmit vast amounts of data with remarkable efficiency.
