Very cost effective bipartitions in graphs

For a graph G=(V,E) and a set of vertices S⊆V, a vertex v∈S is said to be very cost effective if it is adjacent to more vertices in V∖S than in S. A bipartition π={S,V∖S} is called very cost effective if both S and V∖S are very cost effective sets. Not all graphs have a very cost effective bipartiti...
