| Abstract(in English) | Ising-model based solver {￥sato{is gaining increasing}} attention {￥sato{for its efficiency in}} finding approximate solutions forIsing-model based solver is gaining increasing attention for its efficiency in finding approximate solutions for combinatorial optimization problems. In particular, it is known that Ising-model based solver via parallel tempering can obtain the optimal solutions with high probability in a short time. In this paper, we evaluate how the replica topology and the replica temperatures affect the probability of obtaining the optimal solution. Through the experiments on the maximum cut problems, we found that the linear topology gives the best result. With the proposed temperature allocation strategy, the probability of finding the optimal solution has been improved up to 9.6￥,￥%. |
