求解网络的最佳路由问题可以归结为求解全网最小时延问题，用遗传算法理论来解决此种问题，能快速求得全局最优解，且有较高的精度。针对网络规模较大的情况，采取改进的遗传算法，结果表明此法是可行且有效的 The optimal route to solve the network can be attributed to the problem of solving the minimum delay of the whole network. The genetic algorithm theory is used to solve this problem, which can quickly find the global optimal solution with high precision. Aiming at the large-scale network, an improved genetic algorithm is adopted, and the result shows that the method is feasible and effective
