In this paper we consider the problem of finding maximum weight matchings in bipartite graphs with nonnegative integer weights. The presented algorithm for this problem works in O ( W n ω ) 1 1 O denotes the so
The maximum weighted matching problem in bipartite graphs is one of the classic combinatorial optimization problems, and arises in many different applications. Ordered binary decision diagram (OBDD) or algebraic decision diagram (ADD) or variants thereof provides canonical forms to represent and ...

In graph G to be constructed, |U|=|V| and w(e)∈{0,1,2,4},e∈E. As |U|=|V|, any feasible solution to the Min–Max Weighted Matching problem is a perfect matching in G. We start by constructing a bipartite graph G1 that is not complete and where each edge has weight less...

Maximum-matching-of-bipartite-graphsNt**or 上传 二分图的最大匹配问题是一个经典的问题,它要求在不违反任何边的连接性的前提下,尽可能地增加图中的匹配数。对于给定的二分图,我们可以通过以下步骤来解决: 1. 首先,我们需要确定二分图中的所有顶点的集合。在这个例子中,我们有 $n_1$ 个顶点在左半部分,$...
An induced matching $H$ of $G$ is a matching such that no edge of $E$ connects endpoints of two different edges of $H$. We show that in a convex bipartite graph with $n$ vertices and $m$ weighted edges, an induced matching of maximum total weight can be computed in $O(n+m)$...
The maximum matching problem in bipartite graphs can be easily reduced to a maximum flow problem in unit graphs that can be solved in O(m n) time using Dinic's algorithm. We present the original derivation of this result, due to Hopcroft and Karp [HK73]. The maximum matching problem in...

In this paper it is shown that for bipartite graphs the structure of the family of maximum independent sets can be described constructively, in the following sense. For a bipartite graph there are some "basic" maximum independent sets, in terms of which any maximum independent set can be ...
