WebHuffman Codes are Optimal Theorem: Huffman’s algorithm produces an optimum prefix code tree. Proof: By induction on n. When n =2, obvious. Assume inductively that with … In computer science and information theory, a Huffman code is a particular type of optimal prefix code that is commonly used for lossless data compression. The process of finding or using such a code proceeds by means of Huffman coding, an algorithm developed by David A. Huffman while he was a Sc.D. student at MIT, and published in the 1952 paper "A Method for the Construction of Minimum-R…
