Web13 nov. 2012 · This algorithm is called Huffman coding, and was invented by David A. Huffman in 1952 when he was a Ph.D. student at MIT. Huffman Coding In the previous section we saw examples of how a stream of bits can be generated from an encoding. We also saw how the tree can be used to decode a stream of bits. Web8 jan. 2024 · The Huffman encoding algorithm is one of the most commonly used data compression methods in the field of computer science. The algorithm developed by David Huffman [ 29] is used to reduce coding redundancy without loss of data quality. The use of data frequency is the basic idea in the Huffman encoding algorithm.
