Performance Evaluation of QUBO Model for Radio Propagation Analysis with Quantum Annealing

At present, QUBO model for radio propagation analysis has been proposed. The model is applicable to quantum annealing computer, so it can find radio propagation paths faster than conventional ray-tracing method. Here, the model consists of objective function and constraint conditions, and their balance is adjusted by the weight coefficients. This mean that the performance of the model depends on the setting of the weight coefficients. In this paper, suitable weight coefficients are examined.
