DIMACS Workshop on Geometric Optimization May 19 - 21, 2003 DIMACS Center, CoRE Building, Rutgers University Organizers: Joe Mitchell, SUNY Stony Brook, jsbm at ams.sunysb.edu Pankaj Agarwal, Duke University, pankaj at cs.duke.edu Presented under the auspices of the Special Focus on Computational Geometry and Applications. **************************************************************** Combinatorial optimization typically deals with problems of maximizing or minimizing a function of one or more variables subject to a large number of constraints. In many applications, the underlying optimization problem involves a constant number of variables and a large number of constraints that are induced by a given collection of geometric objects; these problems are referred to as geometric-optimization problems. Typical examples include facility location, low-dimensional clustering, network-design, optimal path-planning, shape-matching, proximity, and statistical-measure problems. In such cases one expects that faster and simpler algorithms can be developed by exploiting the geometric nature of the problem. Much work has been done on geometric-optimization problems during the last twenty-five years. Many elegant and sophisticated techniques have been proposed and successfully applied to a wide range of geometric-optimization problems. Several randomization and approximation techniques have been proposed. In parallel with the effort in the geometric algorithms community, the mathematical programming and combinatorial optimization communities have made numerous fundamental advances in optimization, both in computation and in theory, during the last quarter century. Interior-point methods, polyhedral combinatorics, and semidefinite programming have been developed as powerful mathematical and computational tools for optimization, and some of them have been used for geometric problems. Scope and Format: This workshop aims to bring together people from different research communities interested in geometric-optimization problems. The goal is to discuss various techniques developed for geometric optimization and their applications, to identify key research issues that need to be addressed, and to help establish relationships which can be used to strengthen and foster collaboration across the different areas. **************************************************************** Call for Participation: Authors are invited to submit abstracts for talks to be given at the workshop. Please send the organizers an abstract (up to 2 pages) and a draft of a paper (if you have one). (Since there are no formal proceedings for the workshop, submission of material that is to be submitted to (or to appear in) a refereed conference is allowed and encouraged.) Submissions will be due March 31, 2003. Notification of acceptance: April 15, 2003. **************************************************************** Registration Fees: (Pre-registration deadline: May 12, 2003) Regular rate Preregister before deadline $120/day After preregistration deadline $140/day Reduced Rate* Preregister before deadline $60/day After preregistration deadline $70/day Postdocs Preregister before deadline $10/day After preregistration deadline $15/day DIMACS Postdocs $0 Non-Local Graduate & Undergraduate students Preregister before deadline $5/day After preregistration deadline $10/day Local Graduate & Undergraduate students $0 (Rutgers & Princeton) DIMACS partner institution employees** $0 DIMACS long-term visitors*** $0 Registration fee to be collected on site, cash, check, VISA/Mastercard accepted.
