The paper investigates Neural Cellular Automata (NCAs), which are networks of recurrent cells that rely on local connectivity and asynchronous updates. It demonstrates that NCAs can solve complex visual reasoning tasks such as large mazes, Sudoku, and ARC-AGI-1, and that they generalize to larger grids, longer rollouts, and parallel trials. The study also shows that training with sample replay and stochastic perturbations enhances generalization, and that NCAs can recover from damage and scale to raw pixel reasoning.

arXiv:2606. 07108v1 Announce Type: new Abstract: Recent advances in Large Reasoning Models (LRMs) demonstrate remarkable performance improvements by iteratively reflecting, exploring, and executing complex tasks, yet suffer from inefficiencies due to redundant reasoning, known as "overthinking".

arXiv:2607. 04505v1 Announce Type: new Abstract: We advance the hypothesis that human mathematical reasoning, constrained by both the undecidability and the computational intractability of even modest logical fragments, relies fundamentally on pattern matching from domains external to pure deduction.
