ISyE Seminar - Nick Sahinidis

Title:

Convexification and optimization of problems involving the Euclidean norm.

Abstract:

The field of mixed-integer nonlinear optimization has advanced significantly over the past three decades. However, even small instances of many nonconvex optimization problems involving the Euclidean norm are beyond the capabilities of existing algorithms. These problems stem from applications such as molecular energy minimization, object packing, and facility location, and often share specific features that make them challenging. In this presentation, we identify these features, introduce new algorithms to address them, and present numerical results that demonstrate the impact of our techniques. Furthermore, we identify several related open problems and opportunities for analytical and computational advances. This is joint work with Anatoliy Kuznetsov.
