WebJun 24, 2024 · Given a graph, we can use Kruskal’s algorithm to find its minimum spanning tree. If the number of nodes in a graph is V, then each of its spanning trees should have (V-1) edges and contain no cycles. We can describe Kruskal’s algorithm in the following pseudo-code: Initialize an empty edge set T. Sort all graph edges by the ascending order ...
