Neur2BiLO: Neural Bilevel Optimization

Justin Dumouchelle, Esther Julien, Jannis Kurtz, Elias Boutros Khalil

NeurIPS 2024poster

Bilevel optimization deals with nested problems in which *leader* takes the first decision to minimize their objective function while accounting for a *follower*'s best-response reaction. Constrained bilevel problems with integer variables are particularly notorious for their hardness. While exact s…

Neur2RO: Neural Two-Stage Robust Optimization

Justin Dumouchelle, Esther Julien, Jannis Kurtz, Elias Boutros Khalil

ICLR 2024poster

Robust optimization provides a mathematical framework for modeling and solving decision-making problems under worst-case uncertainty. This work addresses two-stage robust optimization (2RO) problems (also called *adjustable robust optimization*), wherein first-stage and second-stage decisions are m…
