| Abstract(in English) | It is well known that the Hop field-type neural network does not always satisfy the constraints such as one neuron in each row and column, so that the network does not always give a feasible solution for a combinatorial optimization problem. To overcome this problem, a solution constructing method has been proposed to solve quadratic assignment problems (QAPs) with a chaotic neural network. However, when we apply the method to a mixed analog/digital chaotic neuron-computer hardware system, the solution constructing method does not show very good performance partly because of noise and circuit non-idealities, in particular, for large-scale QAPs. Therefore, we propose an improved solution constructing method. Through experiments with size-12 QAPs, we show superior performance of the proposed method to the original one. Moreover, simulations show that the proposed technique is effective even without noise and circuit non-idealities. |
