An application of neural networks to a problem in knot theory and group theory (untangling braids)

10 Jun 2022  ·  Alexei Lisitsa, Mateo Salles, Alexei Vernitski ·

We report on our success on solving the problem of untangling braids up to length 20 and width 4. We use feed-forward neural networks in the framework of reinforcement learning to train the agent to choose Reidemeister moves to untangle braids in the minimal number of moves.
