Under our assumption, we have ∑ i ∈ A d i = ∑ j ∈ B d j for this smaller graph. And, the one edge that we deleted will contribute 1 to each side of this, so we will still have equality when we add it back.

WebIn graph theory, a matching in a graph is a set of edges that do not have a set of common vertices. In other words, a matching is a graph where each node has either zero or one edge incident to it. Graph matching is not to be confused with graph isomorphism. Graph isomorphism checks if two graphs are the same whereas a matching is a particular ...
