1、基于混沌局部搜索算子的人工蜂群算法摘要:在求解函數(shù)優(yōu)化問(wèn)題時(shí),為了提升人工蜂群算法局部搜索能力,提出了一種新穎的混沌蜂群算法。新算法設(shè)計(jì)了一種混沌局部搜索算子,并將其嵌入蜂群算法框架中;該算子不僅能夠?qū)崿F(xiàn)在最優(yōu)食物源周?chē)植克阉?,還能夠隨著進(jìn)化代數(shù)增加使搜索范圍不斷縮小。仿真實(shí)驗(yàn)結(jié)果表明,與人工蜂群算法相比,新算法在rosenbrock函數(shù)上,求解精度和收斂速度明顯占優(yōu);此外新算法在多模函數(shù)griewank和rastrigin上,收斂速度明顯占優(yōu)。關(guān)鍵詞:優(yōu)化;混沌;人工蜂群算法;局部搜索artif
