Detection of Hidden Objectives and Interactive Objective Reduction
Seyed Mahdi Shavarani, Manuel López-Ibáñez, Richard Allmendinger
In multi-objective optimization problems, there might exist hidden objectives that are important to the decision-maker but are not being optimized. On the other hand, there might a…
Multi-objective QUBO Solver: Bi-objective Quadratic Assignment
Mayowa Ayodele, Richard Allmendinger, Manuel López-Ibáñez +1
Quantum and quantum-inspired optimisation algorithms are designed to solve problems represented in binary, quadratic and unconstrained form. Combinatorial optimisation problems are…
The Asteroid Routing Problem: A Benchmark for Expensive Black-Box Permutation Optimization
Manuel López-Ibáñez, Francisco Chicano, Rodrigo Gil-Merino
Inspired by the recent 11th Global Trajectory Optimisation Competition, this paper presents the asteroid routing problem (ARP) as a realistic benchmark of algorithms for expensive…
Anomaly-free ALP from non-Abelian flavor symmetry
Chengcheng Han, M. L. López-Ibáñez, Aurora Melis +2
Motivated by the Xenon1T excess in electron-recoil measurements, we investigate the prospects of probing axion-like particles (ALP) in lepton flavor violation experiments. In parti…
Are Evolutionary Algorithms Safe Optimizers?
Youngmin Kim, Richard Allmendinger, Manuel López-Ibáñez
We consider a type of constrained optimization problem, where the violation of a constraint leads to an irrevocable loss, such as breakage of a valuable experimental resource/platf…
The First AI4TSP Competition: Learning to Solve Stochastic Routing Problems
Laurens Bliek, Paulo da Costa, Reza Refaei Afshar +19
This paper reports on the first international competition on AI for the traveling salesman problem (TSP) at the International Joint Conference on Artificial Intelligence 2021 (IJCA…
Constraining Low-Scale Flavor Models with and Lepton Flavor Violation
M. L. López-Ibáñez, Aurora Melis, M. Jay Pérez +2
We present here two concrete examples of models where a sub-TeV scale breaking of their respective and flavor symmetries is able to account for the recentl…
Managing Manufacturing and Delivery of Personalised Medicine: Current and Future Models
Andreea Avramescu, Richard Allmendinger, Manuel López-Ibáñez
With almost 50% of annual commercial drug approvals being Personalised Medicine (PM) and its huge potential to improve quality of life, this emerging medical sector has received in…
Implications of the Muon g-2 result on the flavour structure of the lepton mass matrix
Lorenzo Calibbi, M. L. López-Ibáñez, Aurora Melis +1
The confirmation of the discrepancy with the Standard Model predictions in the anomalous magnetic moment by the Muon g-2 experiment at Fermilab points to a low scale of new physics…
Controlled fermion mixing and FCNCs in a 3+1 Higgs Doublet Model
A. E. Cárcamo Hernández, Ivo de Medeiros Varzielas, M. L. López-Ibáñez +1
We propose a 3+1 Higgs Doublet Model based on the family symmetry supplemented by several auxiliary cyclic symmetries leading to viable Yukawa textures for the Standard Mod…
Reproducibility in Evolutionary Computation
Manuel López-Ibáñez, Juergen Branke, Luís Paquete
Experimental studies are prevalent in Evolutionary Computation (EC), and concerns about the reproducibility and replicability of such studies have increased in recent times, reflec…
Safe Learning and Optimization Techniques: Towards a Survey of the State of the Art
Youngmin Kim, Richard Allmendinger, Manuel López-Ibáñez
Safe learning and optimization deals with learning and optimization problems that avoid, as much as possible, the evaluation of non-safe input points, which are solutions, policies…
Lepton flavour violation from an anomaly-free leptophilic axion-like particle
C. Han, M. L. López-Ibáñez, A. Melis +2
Motivated by the recent Xenon1T result, we study a leptophilic flavour-dependent anomaly-free axion-like particle (ALP) and its effects on charged-lepton flavour violation (CLFV).…

Lorenzo Calibbi, M. L. López-Ibáñez, Aurora Melis +1
The stringent experimental bound on is compatible with a simultaneous and sizable new physics contribution to the electron and muon anomalous magnetic moments $(…
Leptogenesis in with a Universal Texture Zero
Fredrik Björkeroth, Ivo de Medeiros Varzielas, M. L. López-Ibáñez +2

Effective Theories of Flavor and the Non-Universal MSSM
Dipankar Das, M. L. López-Ibáñez, M. Jay Pérez +1
Flavor symmetries à la Froggatt-Nielsen~(FN) provide a compelling way to explain the hierarchies of fermionic masses and mixing angles in the Yukawa sector. In Supersymmetric~(SUSY…
Flavour-changing Higgs decays into bottom and strange quarks in supersymmetry
