Constraint injection improves LLM optimization modeling for vehicle routing

Arxiv CS.AI (top papers)

The paper introduces constraint injection, a method to enhance LLM-based optimization modeling for vehicle routing problems (VRP). Experiments show that injecting domain-specific constraints improves solver code accuracy by over 20% on benchmarks. The approach addresses a key limitation of LLMs in constraint-dense operations research tasks.
