Information processing apparatus of adjusting temperature range in solving optimization problem, computer-implemented method of adjusting temperature range in solving optimization problem, and non-transitory computer-readable storage medium for storing program of adjusting temperature range in solving optimization problem

Abstract

A method includes: acquiring, from a search node configured to perform a search for a ground state represented by plural state variables included in an energy function by using plural temperature values and hold a value of the energy function for the plural state variables, a value of the energy function obtained for the plural state variables at a first temperature value among the plural temperature values; determining whether the value acquired is smaller than a smallest value of the energy function obtained for the plural state variables before reaching the first temperature value; recording update information indicating that the smallest value has been updated at the first temperature value in a case where the value is smaller than the smallest value; and outputting a second temperature value based on the first temperature value at which the update information has been recorded among the plural temperature values.
