Hungarian algorithm is an efficient procedure to find a maximum weight matching in a bipartite graph with parts and and a weight function Usually it is described in terms of potential functions on and looks quite mysterious, as it hides the origin of the procedure, that is a variation of the augmenting path method for finding a maximum (unweighted) matching in Here we describe this point of view.
