Researchers have developed a reinforcement learning pipeline to simplify knot diagrams by learning move proposals and a value heuristic for navigating Reidemeister moves. This system has been applied to complex unknot diagrams, including the $4_1\#9_{10}$ link, where it successfully recovered the established upper bound of three for the unknotting number. Additionally, a self-improving extension of the pipeline was introduced to systematically enhance upper bounds for the unknotting numbers of prime knots. AI
