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...

The methodputEdgeValuetakes three arguments, twoIntegers for the vertices, and the thirdIntegerfor its weight, as specified byMutableValueGraph‘s generic type declaration. As we can see, this is the same input as shown in our diagram from earlier. 3.3. Derive Minimum Spanning Tree Finally, w...
1.For all u∈V do makeset(u); //初始化,让每个点成为独立的连通块 2. X={Æ}; 3. Sort the edges E by weight; //按边的权值大小排序 4. For all edges (u, v) ∈ E in increasing order of weight do //对于条边e(u,v)(权值递增顺序)判断能否加入到图中 if find(u) ≠find(v)...

This problem is the classical minimum spanning tree problem. There are two greedy algorithm available: Prim's and Kruskal. Solution 1. Union Find Kruskal. The core idea is that as long as we have not spanned all vertices(cities), we keep picking the cheapest edge e = (u, v), u is ...

One of the most effective methods to multicast a message is to send the message along the edges of a spanning tree connecting all the members of the group. In this paper, we propose a new fully distributed algorithm to build a minimum spanning tree (MST) in a generic communication network...
