WebKruskal's Algorithm is a greedy algorithm used to find Minimum Spanning Tree (MST) of a graph. A minimum spanning tree is a tree which connects all the vertices of the graph and has the minimum total edge weight. Kruskal's algorithm does so by repeatedly picking out edges with minimum weight (which are not already in the MST) and add them to ...
