Abstract
A neural network processor for solving first-order competitive assignment problems consists of a matrix of N.times.M processing units, each of which corresponds to the pairing of a first number of elements of {R.sub.i } with a second number of elements {C.sub.j }, wherein limits of the first number are programmed in row control superneurons, and limits of the second number are programmed in column superneurons as MIN and MAX values. The cost (weight) W.sub.ij of the pairings is programmed separately into each PU. For each row and column of PUs, a dedicated constraint superneuron insures that the number of active neurons within the associated row or column fall within a specified range. Annealing is provided by gradually increasing the PU gain for each row and column or increasing positive feedback to each PU, the latter being effective to increase hysteresis of each PU or by combining both of these techniques.
