遗传算法的控制参数和策略对算法的运行性能有显著影响,如何合理选取仍有争议。文中以新型碎片标签天线的优化设计为背景,研究控制参数和策略的选取,综合最大适应度和收敛速度两个指标得到了最优策略及其控制参数范围。结果表明,策略的性能和控制参数的取值密切相关,通过合理选取优化策略和控制参数,可以大大减小优化时间,提高天线设计效率。 The control parameters and strategies of genetic algorithm have a significant impact on the performance of the algorithm, and how to choose reasonable is still controversial. In this paper, based on the optimal design of the new tag antenna, the optimal parameters and the range of control parameters are obtained by studying the selection of control parameters and strategies, combining the maximum fitness and the convergence rate. The results show that the performance of the strategy is closely related to the value of the control parameters. By optimizing the optimization strategy and control parameters, the optimization time can be greatly reduced and the antenna design efficiency can be improved.
