Kruskal's Algorithm Kruskal's algorithm is used to find the minimum spanning tree (MST) of a connected, undirected graph. It was developed by Joseph Kruskal in 1956. The algorithm operates by sorting all the edges of the graph by their weights and then adding the shortest edges to the growing spanning tree without forming a cycle until the tree spans all the vertices. Given a weighted, undirected, and connected graph with V vertices and E edges, the task is to find the sum of the weights of the edges in the Minimum Spanning Tree (MST) of the graph using Kruskal's Algorithm. The graph is represented as an edge list. Learn how to find the minimum spanning tree of a graph using Kruskal's algorithm, which sorts the edges in ascending order and adds them to the forest without cycles. See examples, pseudocode, and C++, Java, and Python implementations. In Kruskal's algorithm, we sort all edges of the given graph in increasing order. Then it keeps on adding new edges and nodes in the MST if the newly added edge does not form a cycle. It picks the minimum weighted edge at first and the maximum weighted edge at last.
