| Abstract(in English) | The solution of combinatorial optimization problems based on the Ising model may obtain a quasi-optimal solution by mapping the combinatorial optimization problem to the Ising model and stochastically updating the spin states so that the energy is reduced. On the other hand, updating the spins connected by interactions at the same time may result in a poor quality solution. Therefore, we propose a method to solve the problem quickly by making the Ising model a bipartite graph with the interaction as a edge by duplicating the spins, and updating all spins by updating them only by two times satisfying the condition that spins connected by interaction should not be updated at the same time. Then, by computer experiments, we investigate how the interaction should be put between the duplicated spins. In this paper, a computer experiment was conducted by applying it to the knapsack problem. Better solutions are obtained if interactions are connected as evenly as possible without duplication. |
