一、遗传算法GA 遗传算法(Genetic Algorithm,GA)起源于对生物系统所进行的计算机模拟研究,是一种随机全局搜索优化方法,它模拟了自然选择和遗传中发生的复制、交叉(crossover)和变异(mutation)等现象,从任一初始种群(Population)出发,通过随机选择、交叉和变异操作,产生一群更适合环境的个体,使群体进化到搜索空间中越来越...
在MATLAB中，遗传算法（Genetic Algorithm, GA）是一种模拟自然选择和遗传机制的优化方法。我们以求解函数f(x) = x*sin(10πx) + 2在区间[-1, 2]上的最大值为例进行说明。首先，定义目标函数f(x)：> f = @(x) -(x*sin(10*pi*x) + 2)执行上述命令后，MATLAB会返回函数的匿名函数形式...
