1. In a combinatorial system for measuring the respective values of a physical quality of a plurality of sets of objects such as the weight or quantity thereof, computing a plurality of combinatorial values of said measured values, and discharging those sets of objects the total combinatorial value of which most closely approximates a set value, the method of indicating the results of said combinatorial computations comprising the steps of: arranging said combinatorial values in ranking order of closest approximation to said set value; storing a numerical value representative of each of said combinatorial values and the combination corresponding thereto; selectively retrieving one of said stored numerical values by rank and displaying said selected value on a visual numerical display.
