Let G = (X ∪ Y, E) be a bipartite graph such that the vertices are partitioned into two groups X
and Y , and each edge has one end point in X and one end point in Y .
A 2-1 generalized matching is a set of edges S ⊂ E satisfying the following two conditions:
1. Every vertex in X belongs to at most two edges in S.
2. Every vertex in Y belongs to at most one edge in S.
