His areas of expertise include operations research, software, algorithms and control systems. Cor’s research focuses on worst case analysis of all kinds of combinatorial algorithms, complexity of all kinds of combinatorial problems, solution methods based on polyhedral theory, and approximation methods based on local search. Cor is also involved in applied mathematical modeling, supervising industrial projects and writing papers on mathematical methods. In reviewing papers, Cor is eager to spot false arguments in research papers, and helpful to ameliorate colleagues’ papers, fixing the last details.
