Shannon - fano algorithm
WebbShannon Fano Algorithm is an entropy coding technique used for lossless data compression. It uses the probabilities of occurrence of a character and assigns a unique … WebbThe basis of our algorithm is an extension of Shannon-Fano-Elias codes used in source coding and information theory. This is the first time information-theoretic methods have been used as the basis for solving the suffix sorting problem. Keywords: suffix sorting; suffix arrays; suffix tree; Shannon-Fano-Elias codes; source coding 1. Introduction
