Description
The goal of maximum cardinality matching is to find a matching with as many edges as possible (equivalently: a matching that covers as many vertices as possible). Here, the graph can be any general graph.
Related Problems
Subproblem: Bipartite Graph MCM
Related: Planar Bipartite Graph Perfect Matching
Parameters
V: number of vertices
E: number of edges
