一个关于遗传算法的例子，亲测有效。在理解算法实现基础上就可以很好理解代码啦，主程序直接运行gamain就可以了。(An example of genetic algorithm is given, which is effective. On the basis of understanding the implementation of the algorithm, we can understand the code very well. The main program can run gamain directly.)

基于遗传算法的PID控制算法（MATLAB）(Based on Genetic Algorithm PID control algorithm (MATLAB))

A simple code for GA

说明：  拟牛顿迭代法是相对比较新的一种方法，克服了牛顿迭代需要求导数和求逆的缺点.(Newton iterative method is a relatively new method of Newton shall be required to overcome the derivative and inverse shortcomings.)

MATLAB编写利用牛拉迭代法求解简单电力系统潮流。程序可以分别运用真实值和标幺值计算，可以区分有无变压器计算。程序开始时需要输入节点数量、互联节点之间线路的阻抗等初始化参数，运行可得潮流结果，详见程序内注释。(Written in MATLAB to solve simple oxen pulling power flow using an iterative method. The program can use the true value, respectively, and the per-unit value calculation, you can distinguish whether the transformer calculations. When the program begins to enter initialization parameters such as impedance between the number of nodes, interconnected nodes lines running trend results can be obtained, the detailed program notes.)
