  • Method and system for selecting grammar symbols for variable length data compressors
    Patent number: 7126500
    Abstract: A data compression method and system replaces pairs of symbols in a string of symbols by a single new symbol. A method for selecting the pairs of symbols to be replaced employs a modified greedy algorithm. The method selects a next best pair of symbols for replacement by considering pairs that have a potential for usurping a current best candidate pair of symbols, due to their frequency of occurrence. A minimum savings threshold is evaluated to further avoid exhaustive searches of all possible pairs of symbols.
