Claim 13:
14. An information processing method for obtaining a solution by using an Ising model by an information processing apparatus including an annealing control unit, a spin interaction memory, a random number generation unit, and a spin state update unit, wherein
the annealing control unit controls an annealing step and updates a temperature parameter and a self-action parameter,
the spin interaction memory stores a spin interaction coefficient,
the random number generation unit generates a predetermined random number,
for each annealing step, the spin state update unit
calculates instantaneous magnetic fields of a plurality of spins in parallel by using the spin interaction coefficient,
calculates update probabilities of the plurality of spins in parallel by using the instantaneous magnetic fields, and
updates values of the plurality of spins in parallel by using the update probabilities and the predetermined random number, and

the spin interaction coefficient used for calculating the instantaneous magnetic fields is an interaction coefficient related to the plurality of spins updated in an immediately preceding annealing step.
