这样,我们就可以给出kruskal的完整实现了: 1constintmaxn=100;2//n为节点个数,m为边个数,r存储第i+1小的边的序号,w存储第i条边的权值,u和v存储第i条边的节点序号3intp[maxn],n,u[maxn],v[maxn],w[maxn],r[maxn],m;4//并查集find5intfind(intx){returnp[x]==x?x:p[x]=find(p[x]...

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...

a random node, we don't necessarily need to start with the first one. If you want to challenge yourself, you can modify the code so that it takes a random number (in the correct range of course) as the starting node and observe the algorithm find the same tree in a d...
