Now that we are assured that, given a probability distribution, if there is an optimal uniquely decodable code, there is a prefix-free code with the same average codeword length, the next step is the construction of such optimal prefix-free codes. Huffman’s algorithm , developed by David A. Huffman in 1952 when he was a Ph.D. student at MIT, is just such a simple algorithm.
