APPARATUS, METHOD AND PROGRAM FOR MULTIOBJECTIVE OPTIMIZATION

摘要

PROBLEM TO BE SOLVED: To provide an apparatus, method and program for multiobjective optimization, enabling optimization of a determination variable for an optimization target having a restriction condition, with high accuracy in short time.;SOLUTION: A restriction violation flag indicative of whether or not a determination variable value, which is evaluated by a multiobjective evolutionary algorithm unit 2, an adaptation degree which is output from an optimization target 6, and a restriction variable value which is output from the optimization target 6, violate the restriction condition is stored into a search history memory 3 in a related manner as a search history. Upon decision of a determination variable value to be evaluated, a predetermined number of determination variable values, whose evaluations are completed and which are nearer to an unevaluated determination variable value, are selected from the search history stored in the search history memory 3. It is decided whether or not the unevaluated determination variable value is to be evaluated, based on whether or not the restriction violation flag, corresponding to the predetermined number of selected determination variable values, indicates the violation of the restriction condition.;COPYRIGHT: (C)2010,JPO&INPIT
