Prim Algorithm。这个算法可以分为下面几个步骤: 将顶点集V分成两个集合A和B,其中集合A表示目前已经在MST中的顶点,而集合B则表示目前不在MST中的顶点。 在B寻找与集合A连通的最短的边(u,v),将这条边加入最小生成树中。(此时,与(u,v)相连的顶点,不妨设为C,也应加入集合A中) 重复第二步,直至集合B为空...
使用Prim算法在Python中找到MST的程序 最小生成树是一种为连接无向图的所有顶点而选取的无向图的子集。Prim算法是一种常用的寻找MST的算法。以下是一个使用Prim算法在Python中找到MST的程序示例。 程序示例 import heapq def minimum_spanning_tree(graph, start_vertex
