Reinforcement Learning Enhanced LLM Agents for Complex Vehicle Routing Problems

The experimental results demonstrate that RLEA outperforms the previous state-of-the-ar method, achieving a 16.67% higher success rate while significantly reducing runtime errors, and validate that integrating reinforcement learning with LLM-based reasoning is highly effective for automated optimization modeling.

Compositional Chain-of-Relations for Faithful Knowledge Graph Question Answering with Large Language Models

A relation-centric exploration paradigm is introduced, which uses relations rather than entities as search units and thus avoids unreliable entity pruning and proposes Compositional Chain-of-Relations (CCoR), a simple and effective framework that grounds both phases in the KG with two relation chains.
