The Rotation Graphs of Perfect Matchings of Plane Bipartite Graphs

In the present paper, the minimal proper alternating cycle (MPAC) rotation graph R(G) of perfect matchings of a plane bipartite graph G is defined. We show that an MPAC rotation graph R(G) of G is a directed rooted tree, and thus extend such a result for generalized polyhex graphs to arbitrary plane bipartite graphs. As an immediate result, we describe a one-to-one correspondence between MPAC s...

Bipartite Graphs and Perfect Matchings

When we think about markets creating opportunities for interaction between buyers and sellers, there is an implicit network encoding the access between buyers and sellers. In fact, there are several ways to use networks to model buyer-seller interaction, and here we discuss some of them. First, consider the case in which not all buyers have access to all sellers. There could be several reasons ...

perfect matchings in edge-transitive graph

we find recursive formulae for the number of perfect matchings in a graph g by splitting g into subgraphs h and q. we use these formulas to count perfect matching of p hypercube qn. we also apply our formulas to prove that the number of perfect matching in an edge-transitive graph is , where denotes the number of perfect matchings in g, is the graph constructed from by deleting edges with an en...

Finding Perfect Matchings in Bipartite Hypergraphs

Haxell’s condition [Hax95] is a natural hypergraph analog of Hall’s condition, which is a wellknown necessary and sufficient condition for a bipartite graph to admit a perfect matching. That is, when Haxell’s condition holds it forces the existence of a perfect matching in the bipartite hypergraph. Unlike in graphs, however, there is no known polynomial time algorithm to find the hypergraph per...

Fast Filtering Heuristics for Perfect Bipartite Matchings

The bipartite matching problem has wide applicability. For example, in computer science, researchers have applied bipartite matching in objection recognition, image processing, scheduling, genomics, term rewriting and formal verification, and computer security. We present a heuristic model of perfect matchings in bipartite graphs. The goal of the model is to explore the use of low-cost heuristi...
