用遗传算法求二元函数的最大值，二元函数可以根据自己的需要更改。精度：0.001。 -Using GA to the maximum of the dual function, dual function can be changed according to their needs. Accuracy: 0.001.

使用遗传算法求最短回路。用户输入信息在1.txt中。目前有6个城市，如果权值为-1，表示两个城市之间不可达。遗传算法会被执行5次。-Using genetic algorithm for the shortest loop. The user to enter information in the 1.txt. There are six cities, if the weight is-1, indicating that up between the two cities. Genetic
