在Kruskal算法中,集合A是一个森林,加入集合A中的安全边总是图中连接两个不同连通分支的最小权边。 在Prim算法中,集合A仅形成单棵树,添加入集合A的安全边总是连接树与一个不在树中得顶点的最小权边。 info View Code set heap sort kruskal
1.Sort all the edges in non-decreasing order of their weight.2.Pick the smallest edge. Check if it forms a cycle with the spanning tree formed so far. If cycle is not formed, include this edge. Else, discard it.3.Repeat step#2 until there are (V-1) edges in the spanning tree. ...

用Kruskal算法求无向图 G 的最小生成树。 解法 Kruskal算法是一种贪心算法。初始时将图 G 的边集 E 按照权值,从小到大进行排序,并且生成树。从最小权值的边开始,依次考虑每一条边,对于边 e_i 来说,若将它加入生成树集合 S 中, e_i 不会与 S 中已有的边形成环,那么选取边 e_i 作为生成树中的一条...
