On the convex hull of convex quadratic optimization problems with indicators

no code implementations2 Jan 2022 Linchuan Wei, Alper Atamtürk, Andrés Gómez, Simge Küçükyavuz

We show that a convex hull description of the associated mixed-integer set in an extended space with a quadratic number of additional variables consists of a single positive semidefinite constraint (explicitly stated) and linear constraints.

Ideal formulations for constrained convex optimization problems with indicator variables

no code implementations30 Jun 2020 Linchuan Wei, Andres Gomez, Simge Kucukyavuz

Motivated by modern regression applications, in this paper, we study the convexification of a class of convex optimization problems with indicator variables and combinatorial constraints on the indicators.
