Huffman tree generated from the exact frequencies of the text 'this is an example of a huffman tree'. The frequencies and codes of each character are below. Libgl Error Failed To Load Driver Swrast Steam. Encoding the sentence with this code requires 135 bits, as opposed to 288 (or 180) bits if 36 characters of 8 (or 5) bits were used. (This assumes that the code tree structure is known to the decoder and thus does not need to be counted as part of the transmitted information.)

The process of finding and/or using such a code proceeds by means of Huffman coding, an algorithm developed by while he was a student at, and published in the 1952 paper 'A Method for the Construction of Minimum-Redundancy Codes'. The output from Huffman's algorithm can be viewed as a table for encoding a source symbol (such as a character in a file).
