The problem can be solved with the help of Kruskal and Prim's Algorithm of theminimum spanning tree. Kruskal Algorithm: Kruskal's algorithm follows the greedy approach in each iteration it adds the weight of the minimum edge to a growing spanning tree. Following steps are used in Kruskal alg...
Minimum spanning tree: In a graph, a minimum spanning tress is a tree, which has only edges which are required to connect all the nodes and keeping minimum weight. Now Coming to Prim’s algo, again using wikipedia’s definition 1. Initialize a tree with a single vertex, chosen arbitrarily...

CF Educational Codeforces Round 3 E. Minimum spanning tree for each edge 最小生成树变种 题目链接:http://codeforces.com/problemset/problem/609/E 大致就是有一棵树,对于每一条边,询问包含这条边,最小的一个生成树的权值。 做法就是先求一次最小生成树,标记最小生成树上的边,对于这些边,直接就是原始...
In this case, it is not suitable to use the minimum spanning tree algorithm to build paternity of the two nodes directly. If we can detect the gap between the two nodes and set their weight of edge in MST as a high value which is exceed a lot than the real spatial dis- tance, the...
Minimum Spanning Tree Problems I have just learnt about MST. Can anyone suggest me some problems on Codeforces's problem set that are related to MST ? Thanks. 11631 — Dark roads [UVA] 11747 — Heavy Cycle Edges [UVA]
