Gérard Cornuéjols
Gérard P. Cornuéjols (* 1950 ) is a French mathematician who specializes in operations research and combinatorics ( graph theory ).
Life
Cornuéjols graduated from the Ecole nationale de ponts et chaussées (ENPC) in Paris in 1974 and received his PhD from Cornell University in 1978 . He is director of the Operations Research Faculty at Carnegie Mellon University's Tepper School of Business ( IBM University Professor of Operations Research ).
research
Together with Maria Chudnovsky , Paul Seymour and others, he showed in 2005 by specifying an algorithm that it can be determined in polynomial time whether a graph is perfect . He made important contributions to the Strong Conjecture on Perfect Graphs, which was proven in 2002 by Seymour, Chudnovsky, Robertson, and Thomas.
In addition to operations research ( e.g. facility location ) and graph theory, he dealt with integer programming , optimization methods in financial mathematics and combinatorial optimization .
He is the editor of Mathematics of Operations Research.
Michele Conforti is one of his PhD students .
