WebIn graph theory, the blossom algorithmis an algorithmfor constructing maximum matchingson graphs. The algorithm was developed by Jack Edmondsin 1961,[1]and published in 1965.[2] Given a general graphG= (V, E), the algorithm finds a matching Msuch that each vertex in Vis incident with at most one edge in Mand M is maximized.

WebThis Demonstration shows the steps of Edmonds's famous blossom algorithm for finding the perfect matching of minimal weight in a complete weighted graph. The algorithm uses and modifies a dual solution—the labels on the vertices—and tries to find a perfect matching using only equality edges (edges whose weight equals the sum of the labels ... Web20 jun. 2013 · Ford-Fulkerson is a maximum flow algorithm; you can use it easily to solve unweighted matching. Turning it into a weighted matcing algorithm requires an additional trick; with that trick, you wind up with the Hungarian algorithm. You can also use a min-cost flow algorithm to do weighted bipartite matching, but it might not work quite as well.
