摘要

PPROBLEM TO BE SOLVED: To provide a parametric multi-objective optimization apparatus, method, and program capable of quickly and effectively optimize a decision variable of an optimization target whose objective function varies depending on conditions. PSOLUTION: A condition variable planning unit 2 selects a value of the condition variable of an optimization target 6 in a preset order. A multi-objective evolutionary algorithm unit 4 determines a Pareto-optimal individual set in accordance with a multi-objective evolutionary algorithm for each condition variable selected by the condition variable planning unit 2. A search history storage unit 5 stores a midway individual set and a Pareto-optimal individual set acquired for each condition variable by the multi-objective evolutionary algorithm unit 4. An individual set initialization unit 3 generates an initial individual set for one value of the condition variable selected by the condition variable planning unit 2 by mixing the midway individual set for a plurality of other values of the condition variables stored in the search history storage unit 5.
