WebMay 4, 2024 · Let’s say we have an undirected connected graph, G, which has edges that are labelled by weight. This is a weighted graph: ... This greedy algorithm isn’t always the best, but a therom states ... WebIt is a greedy algorithm in graph theory as in each step it adds the next lowest-weight edge that will not form a cycle to the minimum spanning forest. This algorithm first appeared in Proceedings of the American Mathematical Society, pp. 48–50 in 1956, and was written by Joseph Kruskal. It was rediscovered by Loberman & Weinberger (1957).
