      Unconvinced there’s a big result. “The logical induction algorithm that we provide is theoretical rather than practical.”

      I prodded some of the authors until one linked empirical stuff they've done. https://github.com/GallagherCommaJack/markets …

      Can you summarize? (I’m not motivated to do work on this unless/until someone convinces me it’s exciting)

      I'd like that summarization too! Can't grok how the market works and how to build traders without actually trying.

      A thing that is like this, that actually works and is well-understood, is https://en.wikipedia.org/wiki/Probably_approximately_correct_learning …

      PAC learning doesn't get all the nice properties this algorithm does, but yes it's similar.

      Both this and PAC learning are general frameworks for bounded rationality in a machine-learning context.

      The criteria in the paper defines "good behaviour" in a wider case, ie, cases that aren't PAC-learnable.

      Yes… but are there any cases in which it’s practical? If not, then may be interesting as logic, but not AI.

      Besides... Probability theory isn't poly time. Logic isn't poly time. Why should the unifying theory be poly time?

      If it’s AI, I may be interested now. If it’s logic, I’ll wait until logicians tell me it’s a result. Not holding my breath!
