Researchers have developed a new method called Node-Edge Policy Factorization (NEPF) to address the scalability issues in solving Vehicle Routing Problems (VRPs) on multigraphs. This approach decomposes the routing policy into two stages: node permutation and edge selection, enabling more efficient handling of complex travel options. NEPF demonstrates competitive or superior solution quality compared to existing methods while offering substantial improvements in training and inference speed across various VRP scenarios. AI
