In 1960, Claude Berge introduced the notion of a perfect graph and proposed his famous Strong Perfect Graph Conjecture. Forty years later, the conjecture remains open and perfect graphs have become one of the focal points of graph theory: the bibliography on the subject at has well over 500 items. I will talk about the problem of recognizing perfect graphs in polynomial time.
