Research Interests

While an important aim for Professor Sellmann is to provide actual software systems that can tackle real-world applications efficiently, the abstraction and generalization of originally problem-tailored approaches to standard solution methods that facilitate algorithm design and algorithm engineering for constraint satisfaction and constrained optimization is a key part of his work. Main methodological contributions of his research are the development of Symmetry Breaking by Dominance Detection, Structural Symmetry Breaking, Streamlined Constraint Reasoning, CP-based Column Generation, CP-based Lagrangian Relaxation, and the introduction of associated theoretical notions like Relaxed Consistency and Approximated Consistency.
