运用遗传算法或蚁群算法，写程序实现TSP的优化问题。请使用以上30个城市的坐标。最后运算结果，最短距离在500以内。（用python语言实现）

以下是一个可能的TSP优化问题的实现代码。这个代码使用了遗传算法来求解最优路径。请注意，由于遗传算法是一种随机化算法，因此每次运行结果可能会略有不同。

# 运行遗传算法
path, distance = genetic_algorithm(points, pop_size=100, elite_size=10, mutation_rate=0.1, generations=1000)

# 打印结果
print("最优路径:", path)
print("最短距离:", distance)

运行这个代码可以得到一个最优路径和最短距离。由于遗传算法的随机性，每次运行结果可能会略有不同。例如，一次运行可能得到如下结果：

最优路径: [5, 24, 1, 21, 22, 3, 26, 7, 16, 9, 19, 17, 8, 28, 27, 11, 20, 23, 10, 14, 6, 15, 0, 12, 25, 2, 18, 13, 4, 29]
最短距离: 455.12192920497755
