Chapter24Single-SourceShortestPaths Shortest-pathproblem •即是在一圖上找出兩點間最短路徑。•G=(V,E)是一個WeightedDirectedGraph(加權有向圖)透過Weightfunctionw:ER界定出每個邊的權重。•以p=(v0,v1,…,vk)表一個自v0到vk的Path(路徑)。2 Shortest-pathproblem •定義w(p)=∑i=1w(vi−1...
代码示例 Dijkstra 算法是求解有向图中单源最短距离(Single Source Shortest Path,简称为 SSSP)的经典算法。 最短距离:对一个有权重的有向图 G=(V,E),从一个源点 s 到汇点 v 有很多路径,其中边权和最小的路径,称从 s 到 v 的最短距离。 算法基本原理,如下所示: 初始化:源点 s 到 s 自身的距离...

步骤1:初始化起始节点(source node)到自身的距离为0,到其他所有节点的距离为无穷大。 将包含所有节点的数据对 <节点号,和起始节点的距离>组成字典。即<0,0>为起始节 点0和起始节点0到其自身的距离0。见下图。 步骤2:从字典移除数据对<0,0>并松弛连接起始点0和相邻节点的边。这样可得到距离起始点 ...
