Abstract
An optimization device includes: a memory; and a processor configured to: calculate, as bit operations, when any bit in a bit string representing a state of an Ising model is inverted, an energy change value of the Ising model based on a coefficient indicating magnitude of an interaction between an own bit and the inverted bit in the bit string; output a first signal indicating inversion availability of the own bit according to the energy change value and a second signal indicating the energy change value; select the bit to be inverted in the bit string and the energy change value corresponding to the bit based on the first signal and the second signal; output a fourth signal indicating the selected energy change value; and calculate energy of the Ising model based on the energy change value indicated by the fourth signal.
