中文说明：这个简单的 sga 程序写的 matlab 语言，它用来解最大值 problem.it 用来计算 function.the 函数的最大值被描述为 f_value=21.5+x_1*sin(4*pi*x_1)+x_2*sin(20*pi*x_2) 也是用池来保存最好的价值，以便最佳值将为在计算过程中的记录。此程序是用于 primarial 的学习者，你可以使用它为进一步研究 sga.the 选择策略是轮盘基准值确定方法.
English Description：
this simple sga program is written by matlab language,it is used to solve the max value problem.it is used to compute the max value of a function.the function is described as f_value=21.5+x_1*sin(4*pi*x_1)+x_2*sin(20*pi*x_2) .it is also used a pool to save the best value ,so that the best value will berecorded in the computing procedure. this program is useful for the primarial learner,you can use it for further study of sga.the select stragety is roulette methord.
