DEG: Diffusion-Enhanced GFlowNet for Solving Vehicle Routing Problems
arXiv:2610.39512v1 Announce Type: new Abstract: Traditional neural solvers for solving vehicle routing problems (VRPs) often suffer from limited solution diversity, motivating the development of Generative Flow Network (GFlowNet)-based models. However, the effectiveness of these models is frequently constrained by insufficient flow expansion in high-reward regions, limiting their ability to distribute probability across promising solution routes. Deeper exploration could yield superior results.…
