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...

比如通过MATLAB遗传算法的思想求解f(x)=x*sin(10pi*x)+2.0,-1<=x<=2的最大值问题，结果精确到3位小数。首先在matlab命令窗口输入f=@(x)-(x*sin(10*pi*x)+2) 输出结果为 >> f=@(x)-(x*sin(10*pi*x)+2)f = (x)-(x*sin(10*pi*x)+2)接着输入gatool会打开遗传算法工具箱...

遗传算法(Genetic Algorithm,GA)是一种基于自然选择和遗传操作的随机全局搜索优化算法。它通过模拟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(父代)开始,通过随机选择、交叉和变异操作,产生更具有生存优势的子代,使群体不断向搜索空间最优的方向进化,最后收敛到一群最适应环境...
一、遗传算法 (Genetic Algorithm, GA) 源于达尔文的进化论,将问题的一个解当作种群中的一个个体。 gene:基因 chromosome: 染色体 population:种群 crossover:交叉 mutation:变异 selection:选择 通过多轮的“选择,交叉和变异”,选择适应度最好的个体作为问题的最优解。
