Solving Sparse Mixed-Integer Quadratic Problems: Application to the Unit Commitment Problem with Optimal Power Flow
Ignacio Gómez-Casares, Pietro Belotti, Bissan Ghaddar +1
Mixed-Integer Quadratically Constrained Quadratic Programs (MIQCQP) arise in a variety of applications, particularly in energy, water, and gas systems, where discrete decisions int…
Bound tightening in lifted formulations: (sub)solver-dependent impact on performance in RLT-based algorithms
Julio González-DÃaz, Brais González-RodrÃguez, Ignacio Gómez-Casares
In this paper we explore a relevant aspect of the interplay between two core elements of global optimization algorithms for nonconvex nonlinear programming problems, which we belie…
Impact of domain reduction techniques in polynomial optimization: A computational study
Ignacio Gómez-Casares, Brais González-RodrÃguez, Julio González-DÃaz +1
Domain reduction techniques are at the core of any global optimization solver for NLP or MINLP problems. In this paper, we delve into several of these techniques and assess the imp…
