摘要
通过人口迁移算法优化投影寻踪模型,提出了一种新的水安全智能识别模型。与遗传算法优化的投影模型相对比,人口迁移算法的自身优势有效地避免了网络早熟现象及寻找全局最优解的困扰。从水安全的评价结果来看,用人口迁移算法优化投影寻踪是可行的,并显示出优越性。人口迁移算法为求解投影寻踪模型的非线性约束提供了新的优化方法,并为水安全评价工作提供了新的智能识别模型。
The population migration algorithm has been optimized to the projection pursuit model to propose a kind of new model of intelligent evaluation methods of water security.According to the results which was projection pursuit model has been optimizes by genetic algorithm,population migration algorithm has effectively avoided the network precocious phenomenon,to prevent from missing globally optimal solution.The result indicated that PMA-PPM model is more effective and reasonable to water security assessment than GA-PPM method.This paper proposed the new method for solution Misalignment restraint of projection pursuit model, and has provided the new intelligent evaluation model for the water security.
