A Minimum Spanning Tree is an application of a Disjoint Data Structure. The algorithm is as follows: Sort all the weights in ascending or descending order. Use a vector of edges which consist of all the edges in the graph and each item of a vector will contain 3 parameters: source, destination and the cost of an edge between the source and destination. We also use third-party cookies that help us analyze and understand how you use this website. (A minimum spanning tree of a connected graph is a subset of the edges that forms a tree that includes every vertex, where the sum of the weights of all the edges in the tree is minimized. If it forms a cycle, then it is not included. Here are some key points which will be useful for us in implementing the Kruskalâs algorithm using STL. The Kruskals Algorithm is faster than Prim’s Algorithm as in Prim’s Algorithm, an Edge may be considered more than once whereas in Kruskal’s Algorithm, an Edge is considered only once. Step to Kruskalâs algorithm: Sort the graph edges with respect to their weights. Facebook Twitter Google+. If the graph is connected, the forest has a single component and forms a minimum spanning tree Kruskalâs algorithm can be shown to run in O(E log E) time, or equivalently, O(E log V) time, where E is the number of edges in the graph and V is the number of vertices. a cycle is created in the skeleton, then discard this edge.
