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.

Example Gievn the connections =["Acity","Bcity",1], ["Acity","Ccity",2], ["Bcity","Ccity",3] Return["Acity","Bcity",1], ["Acity","Ccity",2] This problem is the classical minimum spanning tree problem. There are two greedy algorithm available: Prim's and Kruskal. Solution ...
Using this algorithm sub trees are automatically generated from high density region to low density of the graph, where each sub tree will be looked like minimum spanning tree is considered as cluster. The algorithm also detects outliers and hubs, which are present in the data set. Identifying ...
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...

Unlike an edge in Kruskal's, we add vertex to the growing spanning tree in Prim's. Algorithm Steps: Maintain two disjoint sets of vertices. One containing vertices that are in the growing spanning tree and other that are not in the growing spanning tree. Select the cheapest vertex ...
A method of Eppstein [62] can be used to maintain the solution to a bichromatic closest pair problem; combining this with the reduction of Lemma 5 and a fully dynamic graph minimum spanning tree algorithm [69] gives a method with amortized running time O(n1/2logd n + n1 − 2/(⎡...
