Claim 0:
1. An information processing apparatus comprising an annealing control unit, a spin interaction memory, a random number generation unit, and a spin state update unit and obtaining a solution by using an Ising model, wherein
the annealing control unit controls an annealing step and controls a temperature parameter and a self-action parameter,
the spin interaction memory stores an interaction coefficient of a spin,
the random number generation unit generates a predetermined random number, and
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 plurality of spins based on the update probabilities and the predetermined random number.
