arXiv:2606.04860v1 Announce Type: new Abstract: Finding optimal solution paths for combinatorial puzzles like the Rubik's Cube, sliding tile puzzles, and Lights Out remains a classical challenge in artificial intelligence. Heuristic search algorithms, such as A* , guarantee path optimality only when using an admissible heuristic-one that never overestimates the true remaining cost-to-go. Deep reinforcement learning (RL) methods like DeepCubeA train deep neural networks to approximate cost-to-go heuristics. However, standard mean-squared error (MSE) training regularly yields overestimations, vi
The paper leverages recent advancements in deep reinforcement learning and neural networks to address a long-standing challenge in AI search algorithms.
Improving heuristic search with empirically admissible neural heuristics could significantly enhance AI's capability to solve complex combinatorial problems efficiently and optimally.
The ability to train neural networks to provide near-optimal and admissible heuristics will expand the practical applicability of AI in various optimization and decision-making systems.
