double total_distance(const vector<int>& path)                  //total_distance函数用于计算某条路径的长度
{
    double total=0;
    int i;
    for(i=0;i<path.size()-1;i++)
        total+=city_distance[path[i]][path[i+1]];               //从path中取出当前城市和下一个城市，利用city_distance查询距离
    total+=city_distance[path[i]][path[0]];                     //回到起点
    return total;
