Abstract:

将小生境进化理论引入到猴群算法中,提出了一种用于传感器优化布置的小生境猴群算法。采用双重编码的方式,克服了原猴群算法只能解决连续变量优化问题的缺陷,并采用混沌搜索的方式产生初始猴群位置,使猴群均匀分布;将猴群分为多个小生境猴群系统,形成各自独立的搜索空间;基于共享适应度的方法对小生境猴群进行末尾淘汰,并随机初始化产生新的猴子,提高小生境猴群的多样性;利用各个小生境猴群的平均适应度替换机制使得优良猴子位置信息能够得到共享,提高算法的整体搜索性能和收敛效率。文末以大连国贸大厦为例,进行了参数敏感性分析以及传感器优化布置方案的选择,结果表明小生境猴群算法的搜索效率较原猴群算法有了大幅提高,能较好地解决传感器优化布置问题。
