Abstract

An optimization device includes: a state holding unit configured to hold values of a plurality of state variables included in an evaluation function representing energy; a calculation unit configured to calculate a change value of the energy for each of a plurality of state transitions occurred in response to a change in any of the values of the plurality of state variables; a temperature control unit configured to control a temperature value indicating a temperature; and a transition control unit including: a plurality of first selection circuits each configured to randomly select an intermediate candidate from a predetermined number of state transitions based on a propriety of acceptance of each of the predetermined number of state transitions, the propriety being obtained by comparing thermal excitation energy with an energy change for a corresponding state transition, the thermal excitation energy being calculated using each of independent random numbers a number of which is same as the predetermined number; and a second selection circuit configured to randomly select one state transition from intermediate candidates selected by the plurality of first selection circuits.
