The frequencies and codes of each character are below. Encoding the sentence with this code requires 135 (or 147) bits, as opposed to 288 (or 180) bits if 36 characters of 8 (or 5) bits were used. See more 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 … See more In 1951, David A. Huffman and his MIT information theory classmates were given the choice of a term paper or a final exam. The professor, Robert M. Fano, assigned a term paper on the problem of finding the most efficient binary code. Huffman, unable to prove any … See more Informal description Given A set of symbols and their weights (usually proportional to probabilities). Find A prefix-free binary code (a set of codewords) with … See more The probabilities used can be generic ones for the application domain that are based on average experience, or they can be the actual frequencies found in the text being compressed. This … See more Huffman coding uses a specific method for choosing the representation for each symbol, resulting in a prefix code (sometimes called "prefix-free codes", that is, the bit string representing some particular symbol is never a prefix of the bit string … See more Compression The technique works by creating a binary tree of nodes. These can be stored in a regular array, the size of which depends on the number of … See more Many variations of Huffman coding exist, some of which use a Huffman-like algorithm, and others of which find optimal prefix codes … See more
