1. A computer program product that includes a computer readable medium useable by a processor, the medium having stored thereon a sequence of instructions which, when executed by the processor, causes the processor to compress a probability tables through the use of compressed probability tables, wherein the computer program product executes the steps of: determining a probability table that is to be compressed, wherein the probability table contains a plurality of probability elements; compressing the probability table using a first probability table compression method, wherein the probability table compression method creates a first compressed probability table, the first compressed probability table containing a plurality of probability elements; compressing the probability table using a second probability table compression method, wherein the probability table compression method creates a second compressed probability table, the second compressed probability table containing a plurality of probability elements; and merging a first probability element with a second probability element in order to produce a merged probability element.
