Researchers have developed a new framework called Reinforcement Learning Enhanced LLMAgents (RLEA) to automate the modeling of complex Vehicle Routing Problems (VRPs). This multi-agent system uses a lightweight neural Planner trained with Soft Q-learning to manage LLM-based agents. RLEA incorporates an evolutionary memory module and retrieval-augmented generation, allowing it to learn from past experiences and external solver knowledge. In evaluations across 48 VRP variants, RLEA achieved a 16.67% higher success rate and reduced runtime errors compared to previous state-of-the-art methods, demonstrating the effectiveness of combining reinforcement learning with LLM reasoning for optimization modeling.
