The chromatic number x of a graph G is the minimum number of colors necessary to color the vertices of G such that no two adjacent vertices are colored alike. The clique number 01 of a graph G is the maximum number of vertices in a complete subgraph of G. A graph G is said to be perfect if x(H) =m(H
While the famous Berge's Strong Perfect Graph Conjecture remains a major unsolved problem in Graph Theory, the following alternative characterization of perfect graphs was conjectured in 1982 by C. Berge and P. Duchet: A graph G is perfect if and only if any normal orientation of G is kernel-perfect
