Influence Optimization in Networks: New Formulations and Valid Inequalities
Vinicius Ferreira, Artur Pessoa, Thibaut Vidal
Influence propagation has been the subject of extensive study due to its important role in social networks, epidemiology, and many other areas. Understanding propagation mechanisms…
Bilevel Optimization for Feature Selection in the Data-Driven Newsvendor Problem
Breno Serrano, Stefan Minner, Maximilian Schiffer +1
We study the feature-based newsvendor problem, in which a decision-maker has access to historical data consisting of demand observations and exogenous features. In this setting, we…
Neural Networks for Local Search and Crossover in Vehicle Routing: A Possible Overkill?
Ítalo Santana, Andrea Lodi, Thibaut Vidal
Extensive research has been conducted, over recent years, on various ways of enhancing heuristic search for combinatorial optimization problems with machine learning algorithms. In…
Solving a Continent-Scale Inventory Routing Problem at Renault
Louis Bouvier, Guillaume Dalle, Axel Parmentier +1
This paper is the fruit of a partnership with Renault. Their backward logistic requires solving a continent-scale multi-attribute inventory routing problem (IRP). With an average o…
Support Vector Machines with the Hard-Margin Loss: Optimal Training via Combinatorial Benders' Cuts
Ítalo Santana, Breno Serrano, Maximilian Schiffer +1
The classical hinge-loss support vector machines (SVMs) model is sensitive to outlier observations due to the unboundedness of its loss function. To circumvent this issue, recent s…
Workload Equity in Multi-Period Vehicle Routing Problems
Najmeh Nekooghadirli, Michel Gendreau, Jean-Yves Potvin +1
An equitable distribution of workload is essential when deploying vehicle routing solutions in practice. For this reason, previous studies have formulated vehicle routing problems…
