Data-Efficient Interactive Multi-Objective Optimization Using ParEGO

no code implementations12 Jan 2024 Arash Heidari, Sebastian Rojas Gonzalez, Tom Dhaene, Ivo Couckuyt

Multi-objective optimization is a widely studied problem in diverse fields, such as engineering and finance, that seeks to identify a set of non-dominated solutions that provide optimal trade-offs among competing objectives.

Bayesian Optimization of Multiple Objectives with Different Latencies

no code implementations2 Feb 2023 Jack M. Buckingham, Sebastian Rojas Gonzalez, Juergen Branke

Multi-objective Bayesian optimization aims to find the Pareto front of optimal trade-offs between a set of expensive objectives while collecting as few samples as possible.

Bi-objective Ranking and Selection Using Stochastic Kriging

no code implementations5 Sep 2022 Sebastian Rojas Gonzalez, Juergen Branke, Inneke Van Nieuwenhuyse

We consider bi-objective ranking and selection problems, where the goal is to correctly identify the Pareto optimal solutions among a finite set of candidates for which the two objective outcomes have been observed with uncertainty (e. g., after running a multiobjective stochastic simulation optimization procedure).

Constrained multi-objective optimization of process design parameters in settings with scarce data: an application to adhesive bonding

no code implementations16 Dec 2021 Alejandro Morales-Hernández, Sebastian Rojas Gonzalez, Inneke Van Nieuwenhuyse, Ivo Couckuyt, Jeroen Jordens, Maarten Witters, Bart Van Doninck

Adhesive joints are increasingly used in industry for a wide variety of applications because of their favorable characteristics such as high strength-to-weight ratio, design flexibility, limited stress concentrations, planar force transfer, good damage tolerance, and fatigue resistance.
