planar graphdigraphdirected acyclic graphk shortest pathsnext-to-shortest pathGiven an edge-weighted graph G and two distinct vertices s and t of G , the next-to-shortest path problem asks for a path from s to t of minimum length among all paths from s to t except the shortest ones. ...
Finding the shortest loopless path of directed graph passing through specified nodes is the main purpose in this paper. The algorithm for the problem is a challenging work due to the fact that calculating the shortest path visits specified nodes is at least as difficult as the traveling salesman...

graphshortestpath 函数是用来解决最短路径问题的。 语法为: [dist,path,pred]=graphshortestpath(G,S) [dist,path,pred]=graphshortestpath(G,S,T) G是稀疏矩阵,S是起点,T是终点。dist表示最短距离,path表示最短距离经过的路径节点,pred表示从S到每个节点的最短路径中,目标节点的先驱,即目标节点的前面一个...

除此之外,GraphShortestPath函数还支持一些其他的参数设置,例如可以通过'Method'参数选择使用Dijkstra算法或Bellman-Ford算法,也可以通过'Directed'参数设置图是否是有向图。 总之,GraphShortestPath函数是MATLAB中十分实用的函数,能够帮助我们在图结构中快速求解最短路径,方便了我们在科学计算和工程设计中的应用。©...
默认是Dijkstra 算法 是有权的, 我想如果把权都赋1的话, 就相当于没权的了 参数是带权的稀疏矩阵及结点 看看这两个例子(一个有向一个无向), 或许你能找到你想知道的 Create a directed graph with 6 nodes and 11 edges W = [.41 .99 .51 .32 .15 .45 .38 .32 .36 .29 .21];...
