Enhancing Decision Making Through the Integration of Large Language Models and Operations Research Optimization

AAAI 2025technical

Many critical business and societal decisions in areas such as supply chain and healthcare involve numerous potential actions, complex constraints, and goals that can be modeled as objective functions. Mathematical optimization, a core area in Operations Research (OR), provides robust, mathematicall…

Neur2BiLO: Neural Bilevel Optimization

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

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…
