Applying Ising Machines to Multi-objective QUBOs

no code implementations19 May 2023 Mayowa Ayodele, Richard Allmendinger, Manuel López-Ibáñez, Arnaud Liefooghe, Matthieu Parizy

In this work, we extend the adaptive method based on averages in two ways: (i)~we extend the adaptive method of deriving scalarisation weights for problems with two or more objectives, and (ii)~we use an alternative measure of distance to improve performance.

What if we Increase the Number of Objectives? Theoretical and Empirical Implications for Many-objective Optimization

no code implementations6 Jun 2021 Richard Allmendinger, Andrzej Jaszkiewicz, Arnaud Liefooghe, Christiane Tammer

The presence of many objectives typically introduces a number of challenges that affect the choice/design of optimization algorithms.

On the Combined Impact of Population Size and Sub-problem Selection in MOEA/D

no code implementations15 Apr 2020 Geoffrey Pruvost, Bilel Derbel, Arnaud Liefooghe, Ke Li, Qingfu Zhang

This paper intends to understand and to improve the working principle of decomposition-based multi-objective evolutionary algorithms.

Surrogate Assisted Evolutionary Algorithm for Medium Scale Expensive Multi-Objective Optimisation Problems

no code implementations8 Feb 2020 Xiaoran Ruan, Ke Li, Bilel Derbel, Arnaud Liefooghe

The effectiveness of our proposed algorithm is validated on benchmark problems with 10, 20, 50 variables, comparing with three state-of-the-art SAEAs.

An Analysis on Selection for High-Resolution Approximations in Many-Objective Optimization

no code implementations26 Sep 2014 Hernan Aguirre, Arnaud Liefooghe, Sébastien Verel, Kiyoshi Tanaka

This work studies the behavior of three elitist multi- and many-objective evolutionary algorithms generating a high-resolution approximation of the Pareto optimal set.

On the Impact of Multiobjective Scalarizing Functions

no code implementations19 Sep 2014 Bilel Derbel, Dimo Brockhoff, Arnaud Liefooghe, Sébastien Verel

Recently, there has been a renewed interest in decomposition-based approaches for evolutionary multiobjective optimization.

Local Optimal Sets and Bounded Archiving on Multi-objective NK-Landscapes with Correlated Objectives

no code implementations19 Sep 2014 Manuel López-Ibáñez, Arnaud Liefooghe, Sébastien Verel

Such local search algorithms typically return a set of mutually nondominated Pareto local optimal (PLO) solutions, that is, a PLO-set.
