摘　　要：文章结合粒子群算法全局搜索和拟牛顿法局部精细搜索的特点,提出了一种PSO-DFP混合算法。采用标准测试函数对该混合算法的某些参数进行了分析,并给出了一些选取的指导性原则。A hybrid algorithm of PSO-DFP is proposed in this paper, which has well combined the characteristics of PSO＇s group searching and quasi-Newton method＇s local strong searching. Some parameters of hybrid algorithm are analyzed with standard test function. Moreover, guidance principles of selecting are given.
