Kernelization of compressing two-dimensional routing tables with order
Journal Article

Frédéric Giroire, Frédéric Havet, Joanna Moulierac

Given a set of communications X, which is a subset of S×T, (typically S is the set of sources and T the set of destinations), and a port function π:X→P where P is the set of ports, a routing list R is an ordered list of triples which are of the form (s,t,p), (∗,t,p), (s,∗,p) or…

Ray Augmented Supervision for 3D Object Detection
Conference Paper

Huy-Hoang Duong, Adrian Voicila, Guillaume Allibert

Detection Transformer (DETR) has been widely adopted for camera-based multiview 3D Object Detection. Its one-to-one (O2O) Hungarian matching, while effective, leaves many predictions unsupervised during training. This results in weak supervision signals and numerous False…

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…
