DESCRIPTION:On the Semidefinite Representability of Continuous Quadratic Su
 bmodular Minimization With Applications to Moment Problems\n\nWe show that
  continuous quadratic submodular minimization over n bounded variables has
  a semidefinite relaxation that is provably exact when n is at most 3. The
  proof relies on a fundamental connection to copositive optimization. In a
 ddition\, based on extensive numerical testing\, we conjecture that the re
 laxation is exact for all n. We apply this relaxation to two moment proble
 ms in distributionally robust optimization and covariance bound computatio
 n. This work advances the study of continuous submodular minimization and 
 introduces new applications therein.\n\nJoint work with Karthk Natarajan (
 Singapore University of Technology and Design).\n \n\nBio: Sam Burer is th
 e Tippie Rollins Professor and Department Chair in Business Analytics at t
 he University of Iowa. He earned his Ph.D. from Georgia Tech\, and his res
 earch centers on optimization. He has received the INFORMS Computing Paper
  Prize and the SIAM Optimization Test of Time Award. His work has been sup
 ported by National Science Foundation grants\, including a CAREER award. H
 e currently serves as an area editor for Operations Research and an associ
 ate editor for Mathematical Programming. He teaches across all levels of b
 usiness education\, was founding faculty director of two master’s progra
 ms\, and received the University of Iowa’s President and Provost Award f
 or Teaching Excellence.
