Center-Points: A Link Between Discrete Geometry and Optimization

Timm Oertel, Post-doc at Institut für Operations Research Departement Mathematik, Departement Mathematik, Switzerland

Date and Time: Feb 25, 2015 (12:30 PM)
Location: Orchard room (3280) at the Wisconsin Institute for Discovery Building


Optimality condition for mixed-integer convex minimization problems will be discussed and the concept of center-points, a generalization of the median from the one dimensional space to vector spaces. Through the theory of center-points, I will show how to extend the general cutting plane scheme from the continuous setting to the mixed-integer setting. Further, I will present several properties of center-points and how to compute them approximately.
