提出了一种新的种群多样性（ＰＤ） 度量方法，给出了一组ＰＤ 度量标准及计算公式，证明了它们之间的一个数量关系．分别以基因和个体为单元对ＰＤ 进行了研究，揭示了ＰＤ的两种含义－ 实验证明本文引入的几种ＰＤ指标全面反映了ＧＡ 的动态过程，完整描述了ＰＤ各个侧面的含义，克服了以前ＰＤ 定义的局限性．将其用于ＧＡ的运行控制，可大幅度提高ＧＡ的全局收敛性能
A new measure of population diversity (PD) is proposed. A set of PD metrics and calculation formulas are given, and a quantitative relationship between them is proved. The research on PD with gene and individual unit respectively reveals two meanings of PD. The experiment proves that several PD indexes introduced in this paper fully reflect the dynamic process of GA, fully describe the meaning of each side of PD, PD definition of the limitations. Using it for GA operation control can greatly improve the global convergence performance of GA
