Abstract (in Japanese) (See Japanese page) 
(in English) A combination optimization problem is generally NP difficulty or NP completeness. When problem size becomes large, it is difficult for a von Neumann type computer being the mainstream now to calculate a solution
within real time. Many researches using neural networks have been proposed and investigated for solving this problem. Such neural networks have been implemented with the semiconductor circuits. Although the operation speed of the semiconductor circuit has been accelerated by scaling down silicon devices, it is difficult to increase the integration density because of high power density. Compared with a semiconductor circuit, a superconducting circuit has the feature of low power consumption and high-speed processing. The superconducting circuit not only may be able to avoid the problem of the power consumption of a semiconductor circuit, but may be able to realize a still more highly efficient circuit. Our research purpose is to constitute a neural network using a superconducting circuit for solving an optimization problem. A neuron element using a superconductive coupled-SQUID has been already proposed. In this research, we construct a neural network using the coupled-SQUIDs to solve a 4-Queen problem, moreover, we investigate the dynamics in numerical simulations.
