| Abstract(in English) | A fast solution method of combinational optimization problem using a Coherent Ising Machine has been developed. A method for determining the interaction and external magnetic field of a Coherent Ising Machine using Hopfield-Tank Neural Network has been proposed. By computer simulation using the model of a Coherent Ising Machine, it has been shown that the optimal solution of the Traveling Salesman Problem can be obtained by appropriate interaction, external magnetic field and pump rate. In a real machine, there is controllable ranges in these coefficients. In this paper, it is clarified that the optimal solution of Traveling Salesman Problem cannot be obtained in high rate within the controllable ranges of a previously developed real machine. We investigate how the optimal solution can be obtained in high rate and show that the performance can be enhanced by expanding the range of the external magnetic field. |
