WebOverview. Kruskal's algorithm is a greedy algorithm in graph theory that is used to find the Minimum spanning tree (A subgraph of a graph G (V, E) G(V,E) G (V, E) which is a tree and includes all the vertices of the given graph such that the sum of the weight of the edges is minimum) of a given connected, weighted, undirected graph. In case, the graph is not … Web30 dec. 2024 · Definition: A minimum spanning tree consists of N nodes and N-1 edges connecting all the nodes which have the minimum cost (sum of edge weights). Note: It is known as a tree since a tree doesn’t have cycles involved. A graph with N nodes and N-1 edges is equivalent to a tree. Example: Input: Output:
