Perfect Graph Theorem


The graph complement of a perfect graph is itself perfect. Originally known as the weak perfect graph conjecture (Fulkerson 1971), the result was subsequently proved by Lovász (1972) and thenceforth became known as the perfect graph theorem (Skiena 1990, p. 219; Cornuéjols 2002).
