Gaining or Losing Perspective for Piecewise-Linear Under-Estimators of Convex Univariate Functions

Jon Lee, Daphne Skipper, Emily Speakman +1

We study MINLO (mixed-integer nonlinear optimization) formulations of the disjunction $x \in {0} \cup [ℓ, u]$ , where $z$ is a binary indicator of $x \in [ℓ, u]$ ( $0 \leq ℓ < u$ ),…

Constructing lattice-free gradient polyhedra in dimension two

Joseph Paat, Miriam Schlöter, Emily Speakman

Lattice-free gradient polyhedra can be used to certify optimality for mixed-integer convex minimization models. We consider how to construct these polyhedra for unconstrained model…
