Abstract

An information processing apparatus includes an annealing control unit, a spin interaction memory, a random number generation unit, and a spin state update unit and obtains a solution by using an Ising model. The annealing control unit controls an annealing step and a parameter of a temperature and a parameter of a self-action. The spin interaction memory stores the interaction coefficient of a spin. The random number generation unit generates a predetermined random number. The spin state update unit includes a spin buffer that stores values of a plurality of spins, an instantaneous magnetic field calculation unit that calculates instantaneous magnetic fields of the plurality of spins, a probability calculation unit that calculates update probabilities of the plurality of spins, and a spin state determination unit that updates the values of the spins based on the update probabilities and a random number.
