Description

In computer science, the maximum weight matching problem is the problem of finding, in a weighted graph, a matching in which the sum of weights is maximized. Here, the graph is unrestricted; i.e. can be any general graph.

Related Problems

Subproblem: Bipartite Maximum-Weight Matching

Parameters

n: number of vertices

m: number of edges

N: largest weight magnitude
