本文基于遗传算法思想,采用浮点数矩阵表示编码,在遗传算法的进化过程中加入一定的约束条件等方法,探讨了网络结构的设计和学习。经实例分析,在用于建立大坝安全监控预报模型的前馈神经网络设计中,该方法在满足一定约束条件下,能同时有效地寻找合适的网络结构和相应的参数(神经网络的权值和阈值),且在精度和速度上都有较大的提高,为实现实时在线分析评价大坝的安全性态提供了有力的技术支持。-Based on the genetic algorithm, using a float matrix coding, Ge

摘 要:提出一种新的基于Pareto多目标进化免疫算法(PMEIA)。算法在每一代进化群体中选取最优非支配抗体保存到记忆细胞文档中 同时引入Parzen窗估计法计算记忆细胞的熵值,根据熵值对记忆细胞文档进行动更新,使算法向着理想Pareto最优边界搜索。此外,算法基于点在目标空间分况进行克隆选择,有利于得到分布较广的Pareto最优边界,且加快了收敛速度。与已有算法相比, PMEIA在收敛性、多样性,以及解的分布性方面都得到很好的提高。-Abstract:This paperproposed a
