1. A system comprising: a memory; a processor coupled to the memory, said processor functioning as an arbitrator for use with a plurality of modules each having a same input and a zip code result as its output, the result of one of the plurality of modules differing from the result of a different one of the plurality of modules, the arbitrator comprising: a cost tuner for determining a different cost profile associated with each one of the plurality of modules to form a cost profile array, wherein the cost profile includes a cost associated with each one of the results and the cost is determined based upon a rate of which the result is correct, a correct result cost if the result is correct, a rate of which the result is incorrect, and an incorrect result cost if the result is incorrect; and a controller for determining an optimum result from among the results, the controller utilizing the cost profile array from said cost tuner to determine the optimum result.
