The parameter selection in Quadratic PSO deeply affects the performance of Quadratic PSO,so this paper optimizes the parameter using standard PSO and then gives ranges of Quadratic PSO s parameters through experiments.
在对标准微粒群算法模型及其机理进行分析的基础上改进了标准微粒群算法的进化方程,提出了二次微粒群算法,由于其几个主要参数的选择很大程度上影响到算法的性能,故用标准微粒群算法对二次微粒群算法参数的选择进行优化,得到其参数的选取范围,并在仿真所得的范围内选取一组参数对典型测试函数进行仿真,将结果与标准微粒群算法的仿真结果进行比较,结果表明性能有很大提高,且二次微粒群算法能更快更好的找到全局最优点,这说明了这种算法的正确性和有效性。
Using the method of quadratic differential,we obtain that the Affine transformation in angle region is not an extremal mapping with its boundary values,and give explicitly an unique extremal Teichmller mapping with the same boundary values as the Affine transformation.
