1.本程序演示的是用简单遗传算法随机一个种群,然后根据所给的交叉率,变异率,世代数计算最大适应度所在的代数
2.演示程序以用户和计算机的对话方式执行,即在计算机终端上显示“提示信息”之后,由用户在键盘上输入演示程序中规定的命令;相应的输入数据和运算结果显示在其后。
3.测试数据
输入初始变量后用y=100*(x1*x1-x2)*(x1*x2-x2)+(1-x1)*(1-x1)其中-2.048<=x1,x2<=2.048作适应度函数求最大适应度即为函数的最大值

粒子群算法(PSO)属于进化算法的一种,和模拟退火算法相似,它也是从随机解出发,通过迭代寻找最优解,它也是通过适应度来评价解的品质,但它比遗传算法规则更为简单,它没有遗传算法的“交叉”(Crossover) 和“变异”(Mutation) 操作,它通过追随当前搜索到的最优值来寻找全局最优。这种算法以其实现容易、精度高、收敛快等优点引起了学术界的重视,并且在解决实际问题中展示了其优越性。粒子群算法是一种并行算法。该程序适用于MATLAB中粒子群算法的实现。-
