Abstract
An optimization apparatus includes: a memory; and a processor coupled to the memory, the processor being configured to (a): execute transformation processing that includes transforming an input first cost function to a second cost function by using at least any one of 'Legendre transformation,' 'Lagrange function,' and “Wolfe's duality theorem,” (b): execute binary expansion processing that includes acquiring values in an Ising format by carrying out binary expansion for values relating to coefficients of the second cost function, (c): execute Ising machine processing that includes seeking values that represent a ground state regarding the values in the Ising format relating to the coefficients of the second cost function, and (d): execute reverse binary expansion processing that includes acquiring values that minimize the first cost function by carrying out reverse binary expansion for the sought values that represent the ground state.
