Efficiently solving a vehicle routing problem (\(\mathcal{VRP}\)
) in a practical runtime is a critical challenge for delivery management companies. This pa...
This poster conceptually lays out recent advances in trustworthy machine learning (ML) that are of great interest for power systems applications like virtu...

The truck loading and inventory routing problems are the two most important decisions made by companies replenishing petrol stations. This paper investigates...
BibTeX reference
We develop a worst-case evaluation complexity bound for trust-region methods in the presence of unbounded Hessian approximations. We use the algorithm of Ar...
BibTeX referenceCorrigendum: A proximal quasi-Newton trust-region method for nonsmooth regularized optimization
The purpose of the present note is to bring clarifications to certain concepts and surrounding notation of Aravkin et al. (2022). All results therein contin...

We develop a trust-region method for minimizing the sum of a smooth term \(f\)
and a nonsmooth term \(h\)
, both of which can be nonconvex.
Each iteratio...
In this work, we study a class of two-player deterministic finite-horizon difference games with coupled inequality constraints, where both players have two t...
BibTeX reference
The fine-tuning of Large Language Models (LLMs) has enabled them to recently achieve milestones in natural language processing applications. The emergenc...
BibTeX reference
Bus scheduling in public transit consists in determining a set of bus schedules to cover a set of timetabled trips at minimum cost. This planning process has...
BibTeX reference
Yield uncertainty is an important issue in various industries such as agriculture, food, and textile where the production output is reliant on uncontrollable...
BibTeX referenceAlgorithme primal ajoutant des variables pour le problème du partitionnement d'ensemble généralisé
Le problème du partitionnement d'ensemble est un problème de programmation en nombres entiers très étudié. Le problème consiste à trouver une partition de tâ...

The cosine measure was introduced in 2003 to quantify the richness of a finite positive spanning sets of directions in the context of derivative-free direc...
BibTeX referenceThe heterogeneous-fleet electric vehicle routing problem with nonlinear charging functions
This paper introduces the Heterogeneous-Fleet Electric Vehicle Routing Problem with Nonlinear Charging Functions (HEVRP-NL). This problem involves routing a ...
