Title: “Interior Methods for Mathematical Programs with Complementarity Constraints (MPCCs)"

Speaker: Gabriel Lopez-Calva, Northwestern University

Date/Time: Monday, April 18, 2005, 11:00-12:15 am (MT)

Location: Building 980, Room 24 (Sandia NM), Building 915 Room S101 (Sandia CA)

Brief Abstract: I will start with a brief introduction to the notion of 'complementarity' and to Mathematical Programs with Complementarity Constraints (MPCCs), as a motivation. I will present then a framework for the numerical solutions of MPCCs using interior methods, based on an exact penalty reformulation. I will go over the main contributions of our work, namely, global and local convergence results, and strategies to handle the penalty parameter for effective practical implementations. Numerical results will also be presented. This is joint work with Sven Leyffer (Argonne National Laboratory) and Jorge Nocedal (Northwestern University). [Time permitting, I will briefly talk about my current research projects, at the end.]
