Energy efficiency optimization in MIMO interference channels: A successive pseudoconvex approximation approach [PDF]

open access: yes, 2018
In this paper, we consider the (global and sum) energy efficiency optimization problem in downlink multi-input multi-output multi-cell systems, where all users suffer from multi-user interference.

Using convex nonlinear relaxations in the global optimization of nonconvex generalized disjunctive programs [PDF]

open access: yesComputers & Chemical Engineering, 2013
In this paper we present a framework to generate tight convex relaxations for nonconvex generalized disjunctive programs. The proposed methodology builds on our recent work on bilinear and concave generalized disjunctive programs for which tight linear relaxations can be generated, and extends its application to nonlinear relaxations.

A joint decomposition method for global optimization of multiscenario nonconvex mixed-integer nonlinear programs [PDF]

open access: yesJournal of Global Optimization, 2019
This paper proposes a joint decomposition method that combines La- grangian decomposition and generalized Benders decomposition, to efficiently solve multiscenario nonconvex mixed-integer nonlinear programming (MINLP) problems to global optimality, without the need for explicit branch and bound search.

A Status Report on Conflict Analysis in Mixed Integer Nonlinear Programming

open access: yes, 2019
Mixed integer nonlinear programs (MINLPs) are arguably among the hardest optimization problems, with a wide range of applications. MINLP solvers that are based on linear relaxations and spatial branching work similar as mixed integer programming (MIP ...
