I am trying to follow the steps of covering the zeros with the minimum number of lines in the Hungarian Method as follows: Tick all unassigned rows. If the ticked row has zeros, then tick the correspondent column. Within the ticked column, if there is an assignment, then tick the correspondent row. Draw a line above each un-ticked row and ...

Weby then Mis a maximum-weight perfect matching. 19.2 The Hungarian Method Here we let L;Rdenote the two sides of the bipartite graph G= (V;E). The Hungarian Method is a primal-dual algorithm that simultaneously constructs a perfect matching Mand a feasible dual solution y witnessing optimality of M(as per Lemma 1). We call it a primal-dual ... WebThis is the assignment problem, for which the Hungarian Algorithm offers a solution. Notice: although no one has chosen LB, the algorithm will still assign a player there. In fact, the first step of the algorithm is to create a complete bipartite graph (all possible edges exist), giving new edges weight 0. Define a weighted bipartite graph in ...
