In this section, we describe the parallel Pothen–Fan algorithm, which we use for comparison with push–relabel in our experiments. It was introduced in Azad et al. [3] and found to be the fastest bipartite matching algorithm based on augmenting paths for multicore computers. We give a shor...

The Hungarian algorithm finds a maximum independent edge set on a graph. The algorithm starts with any matching M and constructs a tree via a breadth-first search to find an augmenting path, namely a path P that starts and finishes at unmatched vertices
Hungarian Algorithm: A variant of weighted bipartite matching problem is known as assignment problem. In simple terms, assignment problem can be described as havingNjobs andNworkers, each worker does a job for particular cost. Also, each worker should be given only one job and each job should...
We present novel symbolic ADD formulation and algorithm for maximum weighted matching in bipartite graphs. The symbolic algorithm implements the Hungarian algorithm in the context of ADD and OBDD formulation and manipulations. It begins by setting feasible labelings of nodes and then iterates through ...
