Berge’s well known conjecture (SPGC) can be formulated as follows: “A graph G is perfect if and only if it contains neither an odd hole nor an odd anti-hole”. In this formulation an odd hole is a chordless circuit on an odd number of nodes and an odd anti-hole the complement of an odd hole. In the past the conjecture has been verified for several classes of graphs, among which planar and 3-chromatic graphs.
