We were genuinely impressed by Yann LeCun’s recent announcement about his Sudoku solver based on Energy-Based Models here: https://logicalintelligence.com/yann-lecunSo we (a software engineer and prodigy mathematician) worked in the weekend to see if we can beat it and we did!If Kona solves puzzles in 313 milliseconds, we currently solve 270,000 puzzles per second!We do not know the internal mechanics behind Logical Intelligence’s system, but we are happy to share ours in the webpage there is a full description, code and also a paper published.Why people are obsessed with Sudoku: we think is because being a CSP, it can solve some serious business problems such as work scheduling, resource allocations and logistic optimization.For any questions reach me out to: [email protected].

Could you build this?
No Developing novel Energy-Based Geometric Models for constraint-satisfaction reasoning like Sudoku requires advanced academic mathematics and machine learning research.
What it would actually take: This project requires designing non-standard energy functions, manifold optimization routines, and neural network architectures based on geometric deep learning and statistical physics. Implementation entails custom loss functions, differentiable relaxation of discrete constraints, and specialized gradient/energy descent algorithms in PyTorch or JAX. It requires an AI researcher or mathematical physicist specializing in energy-based models.
