WebbKarger's algorithm is a randomized algorithm to find the minimum cut in an unweighted and undirected graph in which we pick up a random edge and contract or coalesce the … Webb20 mars 2024 · The algorithm takes a graph and repeatedly contracts randomly selected edges until only two nodes are left. By repeating this procedure n times and remembering the smallest number of edges between the remaining two nodes over the n trials, the algorithm returns the correct number of minimum edges with a relatively high probability.
