摘要:
阐述了带转向延误和限制的最短路径问题(SP-Turn)的基本原理,系统介绍了现有的求解方法,包括扩展网络法、对偶网络法和弧标号算法,并提出了一个节点标号算法用于对比.分析指出弧标号、节点标号算法在算法原理上是一致的,对偶网络法是对它们的直观化.同时指出在SP-Turn方法中,扩展邻接表是高效的网络表示形式,在合理选择的前提下,一般SP算法的标号设定、标号修正等标号技术同样适用,最短路径可由节点至弧的形式转换为节点至节点的常规形式.
Abstract:
The theory of shortest path problem with turn penalties and prohibitions(SP-Turn)was introduced, and its state-of-the-art approaches, including method of expanded-network, dual-network and arc-labeling, were reviewed, while a new node-labeling algorithm was proposed for comparison. Further analysis shows that arc-labeling and node-labeling algorithms have no difference in fundamentals, while the dual-network method is their visualized version. We also point that the extended adjacency list is very efficient for network representation in SP-Turn methods, those labeling techniques used in ordinary shortest path algorithms, i.e. label-setting and label-correcting, can also be adopted after problem-specific choice, and the shortest paths of node-to-arc structure can be transformed to the standard node-to-node ones.
