Solver-Informed RL: Grounding Large Language Models for Authentic Optimization Modeling

NeurIPS 2025poster

Optimization modeling is fundamental to decision-making in fields such as supply chain management, logistics, and financial engineering, but its complexity presents a major barrier to adoption. Automating model creation from natural language is key to improving efficiency and access. However, while…

Decentralized Gradient-Free Methods for Stochastic Non-smooth Non-convex Optimization

AAAI 2024technical

We consider decentralized gradient-free optimization of minimizing Lipschitz continuous functions that satisfy neither smoothness nor convexity assumption. We propose two novel gradient-free algorithms, the Decentralized Gradient-Free Method (DGFM) and its variant, the Decentralized Gradient-Free Me…
