Title :関数最適化アルゴリズムSCE-UA 法の性能評価と改良
Authors :藤井 厚紀
Issue Date :Sep-2011
Abstract :This paper investigates the characteristics of the shuffled complex evolution (SCE-UA)global optimization method and proposes a modified SCE-UA algorithm. The search performance of the SCE-UA method was compared with that of a real-coded genetic algorithm with the simplex crossover (SPX) using several benchmark functions. The SCE-UA method showed higher performance than SPX for all test functions. The“mutation step”on the SCE-UA algorithm was modified because of a decrease in optimization performance for the objective function that has the optimal solution near the boundary of the search space. As a result, the modified SCE-UA method showed a high efficiency for optimization. It is thought that the improved SCE-UA method can be effectively applied to various problems with function optimization.
