摘要
在组合优化过程中,往往需要获得从起点到终点之间的最短路,而其所考虑的目标可能是一个与时间相关的变量.同时,对于网络中的节点往往有宵禁的限制(curfews).给出时变条件下有软、硬宵禁限制的最短路模型,设计了求解时变条件下有宵禁限制最短路的算法,并对算法的复杂性进行了分析.最后给出了一个应用算例.
Shortest path problem is a basic problem in the combinatorial optimization. The objective in the network is time-varying. Moreover, there will be curfews in some nodes in the network. The paper develops the models for time-varying shortest path problem with soft and hard curfews and gives the algorithm for them. Then, the complexity of the algorithm is discussed. At last, a case is studied.
