Benchmarking Metaheuristics for Mixed-Integer Optimization
Conference Paper
Thomas Lang, Denis Pallez
Mixed-integer optimization (MIO) involves solving a problem defined by both discrete and continuous decision variables. Although common in real-world applications, MIO is difficult to solve because traditional metaheuristics are primarily designed for a single variable type…
Continuous Pareto Nested Rollout Policy Adaptation for Multiobjective Sequential Optimization
Conference Paper
Nathan Amoussou, Denis Pallez
Multiobjective sequential optimization problems consist of building a solution as a sequence of decisions, while searching for optimal trade-offs among multiple, often conflicting, objectives. In this context, the Pareto-Nested Rollout Policy Adaptation (P-NRPA) algorithm has…
Distributed Rigid Formation Control of Aerial Robots via Spherical Event Cameras
Conference Paper
Andrea Infanti, Bojan Mavkov, Fabio Morbidi, Guillaume Allibert
This paper addresses the challenging problem of designing distributed rigidity-based formation control strategies for aerial robots with a spherical event camera as the primary on-board sensor. In fact, since accurate distance measurements are seldom available in aerial…
Segment-Safe Control Barrier Functions for Model Predictive Control
Conference Paper
Andrea Pagnini, Ezio Malis
Ensuring inter-sample safety for continuous-time robotic systems under discrete Model Predictive Control (MPC) remains a key challenge. Standard discrete MPC risks safety violations between sampling instants, while existing conservative solutions often sacrifice performance. We…
SEF-CLGC at SemEval-2026 Task 11: Logical Notation Impact on Language Model Performance
Conference Paper
Hanna Abi Akl, Fabien Gandon, Catherine Faron, Pierre Monnin
This paper revisits our pipeline called Syllogistic Evaluation Framework-Common Logic Grammar Construction (SEF-CLGC). We combine formal logical notations with Small Language Models (SLMs) to evaluate reasoning performance on the SemEval-2026 Task 11 Subtask 1: Disentangling…
Sub-cellular stereotypy in ascidian embryogenesis
Conference Paper
Haydar Jammoul, Kilian Biasuz, Benjamin Gallean, Patrick Lemaire, Grégoire Malandain
Ascidians are chordates closely related to vertebrates, including humans, and are widely used as model organisms in developmental biology to study embryonic formation and development. Ascidian development is highly stereotyped at the cellular level. Here, we present a…
