arXiv:2606.06518v1 Announce Type: cross Abstract: Sudoku is a representative constraint satisfaction problem that requires global structural reasoning under strict discrete constraints. The existing works of solving Sudoku mainly focus on two dominant approaches, i.e., traditional heuristic and deep learning solver. However, they suffer from two complementary limitations: learning-based solvers lack hard correctness guarantees, while complete symbolic solvers are still prone to long-tail search. To address these shortcomings, we propose a novel diffusion model-guided approach, termed as DiBS,
The paper presents a novel approach to combining the strengths of traditional heuristic solvers and deep learning, addressing existing limitations in constraint satisfaction problems at a time of increased focus on robust AI. The publication date in 2026 suggests this is a forward-looking development in AI research.
This research addresses fundamental challenges in AI problem-solving, potentially leading to more reliable and efficient autonomous agents capable of tackling complex, real-world constraint satisfaction tasks, moving beyond current learning-based limitations.
The proposed 'DiBS' method offers a pathway to AI systems that can solve complex problems like Sudoku with both learned efficiency and guaranteed correctness, bridging a gap between symbolic AI and deep learning.
