Abstract
In an optimization apparatus, calculation circuits individually calculate a change in energy based on first local field values each associated with one of n bits (n is an integer greater than or equal to 2) amongst a plurality of bits corresponding to spins in an Ising model, values of the n bits, and one or more weight values representing strength of interaction among the n bits. The change in energy is caused by flips of the n bits. An update bit selection circuit selects the n bits for which value update is accepted, based on the magnitude relationship between thermal excitation energy and each of the calculated changes in energy. An update circuit flips the n bits, and also updates, based on the flips of the n bits, second local field values including the first local field values and each associated with the plurality of individual bits.
