The present paper shows how to construct a maximum matching in a bipartite graph with n vertices and m edges in a number of computation steps proportional to (m + n)x/. Key words, algorithm, algorithmic analysis, bipartite graphs, computational complexity, graphs, matching 1. Introduction. Sup...
In this work we consider the problem of the existence of a perfect matching of a given weight in edge-weighted complete and complete bipartite graphs. It is known that such a problem is NP-hard in general. We propose a polynomial solution algorithm in the case when the edges have weights ...
1.3 二分图完美匹配(Perfect matchings in bipartite graphs)# Def. Given a graph G=(V,E), a subset of edges M⊆E is a perfect matching if each node appears in exactly one edge in M. Notation. Let S be a subset of nodes, and let N(S) be the set of nodes adjacent to nodes in...

In a complete bipartite graph G=(U,V,E) with weighted edges, set U of vertices is partitioned into disjoint subsets called components. The aim is to find an inclusion-wise maximal matching that minimizes the maximum weight of a component (sum of the weights of those edges incident to a ...

BAIRE MEASURABLE MATCHINGS IN ACYCLIC LOCALLY FINITE BOREL GRAPHS A graph on a set X is an irreflexive symmetric subset G of X x X. A matching of G is a fixed-point-free involution ι of a subset of X whose graph is contained in G. A matching is perfect if its domain is X.A G-...
In this paper we consider the approximability of the maximum induced matching problem (MIM). We give an approximation algorithm with asymptotic performance ratio d−1 for MIM in d-regular graphs, for each d⩾3. We also prove that MIM is APX-complete in d-regular graphs, for each d...
