Convexification and optimization of problems involving the Euclidean norm

The Lehigh ISE Department is pleased to announce that Nick Sahinidis, the Butler Family Chair and Professor of Industrial & Systems Engineering and Chemical & Biomolecular Engineering at the Georgia Institute of Technology, will give the Spencer C. Schantz Distinguished Technical Talk titled “Convexification and optimization of problems involving the Euclidean norm,” on Tuesday, December 3, 2024, from 11:00 a.m. to 12:00 p.m. in Mohler Laboratory room 453, 200 West Packer Avenue, Bethlehem, PA.

 

 

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.

Lehigh ISE Spencer C. Schantz Distinguished Lecture Series:

This lecture series is endowed in the name of the late Spencer C. Schantz, who graduated from Lehigh in 1955 with a B.S. in Industrial Engineering. Following progressive responsibilities with several electrical manufacturing companies, in 1969 he founded U.S. Controls Corporation and became its first CEO and President. The Spencer C. Schantz Distinguished Lecture Series was established by his wife Jerelyn as a valuable educational experience for faculty, students, and friends of Lehigh’s Industrial and Systems Engineering department.
