Given a general graph G = (V, E), the algorithm finds a matching M such that each vertex in V is incident with at most one edge in M and |M| is maximized. The algorithm was developed by Jack Edmonds in 1961, and published in 1965. We do provided a single function to download and compile Blossom V, and to setup the integration with Qsurface automatically. The Blossom algorithm would, in this case, return 2 edges such that the sum of their weights is maximized and such that each vertex in our graph is incident to exactly 1 of those edges. 1.
