On the convergence of cutting-plane methods for robust optimization with ellipsoidal uncertainty sets
Provides theoretical convergence guarantees for practitioners using cutting-plane methods with ellipsoidal uncertainty sets, which were previously lacking.
This paper proves that a cutting-plane algorithm for robust optimization with ellipsoidal uncertainty sets converges in a finite number of steps, addressing a gap in theoretical guarantees.
Recent advances in cutting-plane strategies applied to robust optimization problems show that they are competitive with respect to problem reformulations and interior-point algorithms. However, although its application with polyhedral uncertainty sets guarantees convergence, finite termination when using ellipsoidal uncertainty sets is not theoretically guaranteed. This paper demonstrates that the cutting-plane algorithm set out for ellipsoidal uncertainty sets in its more general form also converges in a finite number of steps.
