arXiv:2605.26776v1 Announce Type: new Abstract: In recent years, Deep Reinforcement Learning (DRL) has achieved substantial progress on Vehicle Routing Problems (VRPs). However, existing DRL-based methods are typically trained on instances generated from a uniform distribution, which limits their performance under real-world distribution shifts. In this paper, we aim to develop a generalization-oriented model that partitions the policy network into multiple modules and adaptively recombines modules to form specific policies during inference. Specifically, we propose Residual Refined Experts wi
The increasing complexity and real-world application of AI demand more generalized and robust solutions for established optimization problems like VRPs, pushing research towards adaptive models beyond uniform training distributions.
This research addresses a fundamental limitation in current DRL applications, moving towards AI systems that can perform reliably in dynamic, real-world scenarios rather than just controlled environments.
AI models for logistical optimization may become significantly more adaptable and reliable for various real-world conditions, reducing the need for extensive retraining and improving operational efficiency.
