Leveraging Structural Constraints for Diffusion-based Neural TSP Solvers
Researchers have developed a new method called Projected Consistency Inference (PCI) to improve the performance of diffusion-based neural solvers for the Traveling Salesman Problem (TSP). PCI replaces computationally intensive gradient refinement with structure-aware projections and local search, resulting in better optimality gaps and reduced inference times compared to existing methods like FT2T. This approach offers a practical and principled way to enhance neural TSP solvers by incorporating structural constraints during inference. AI
