Abstract
Provided is an optimization method including executing a ground state search for an interaction model by a ground state search in a surrogate interaction model including D (D is a natural number of three or more) variable groups each having N continuous variables by using an information processing apparatus, the interaction model having a third-order or higher-order energy function including N (N is a natural number) continuous variables and discrete variables. The ground state search is executed based on simulated annealing. An interaction relation of the surrogate interaction model has a complete D-part graph structure. A coupling is set between i-th variable pairs in the respective variable groups of the surrogate interaction model. The information processing apparatus is operated to simultaneously update all variables of one variable group from among the D variable groups when performing a state transition in the surrogate interaction model.
