INPUT: edges – … WebBipartite Graph. A graph is said to be bipartite if we can divide the set of vertices in two disjoint sets such that there is no edge between vertices belonging to same set. Let's break it down. Here we are dividing set of vertices in two groups (or sets). Each vertex goes into one of these groups. This is like labelling each vertex either A or B.

"WebMar 26, 2012 · Consider a bipartite graph with E = k + 1. Delete one edge and we have a bipartite graph with E = k. 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. " - Graph theory bipartite
