Abstract
An optimization apparatus finds the ground state of an Ising model that represents a target problem by running a simulation of state changes of the Ising model that occur upon reduction in a magnetic field applied to the Ising model. In doing so, the optimization apparatus adds a value corresponding to noise to some of coefficients used in the simulation. Then, the optimization apparatus performs a first process of real time propagation of reducing strength of the magnetic field as time in the simulation progresses and a second process of reducing energy of the Ising model based on an imaginary time propagation method.
