We are studying a multiplexed spatial-photonic Ising machine that enables to increase the flexibility in the expression of problems by space-division multiplexing. In optimization problems that the constraint term and the cost term should be considered, it is necessary to set appropriately the coefficient ratio between these terms. In this study, we investigated on an optical system to handle the property of searching solutions by tuning the intensity ratio of the encoding light beams, and evaluated the performance of the system.
