For example, one that brains appear to be able to solve in polynomial time but computers can't, or one optimized for the brain's innate capabilities - like language learning, or different possibilities computed at once.
I've found some things about the brain's computational abilities, like a "predictive coding hierarchy" that helps it learn languages and Joe Z. Tsien's Theory of Connectivity in which neurons group into cliques and motifs to process complex concepts, but I haven't really found anything from an algorithmic perspective. My ultimate goal is to see if there's an encryption algorithm that can be done by a person with pencil and paper, but that can't be easily cracked by a computer.
Has any research been done on this? Thanks for any lead you may have.
