14:35:49 <impomatic> Does anyone know an algorithm to calculate the nash equilibrium percentage of a big matrix?  The kind of equilibrium where the matrix contains scores of something in the row vs something in the column, and the equilibrium is x% percent of the first row, y% of the second row, z% of the third row, etc, which gives everything exactly the same score.

17:13:54 <korvo> PPAD-complete is more-or-less FNP-complete, FWIW; we haven't proven it yet, but there's piles of evidence and my prior is at something like 97%.
17:14:30 <korvo> IOW free markets probably are not efficient; there are probably cases where a free market can't avoid sitting exponentially far from Nash equilibrium for exponentially long.
17:15:22 <int-e> you mean on top of all the other things that are obviously going wrong with that theory?
17:15:29 <int-e> (rational agents, lol)
17:15:53 <korvo> Of course, yeah. (Personally I'm still waiting for a categorical formulation of markets; absent one, I'm not convinced that they have a nice algebraic theory.)
17:18:56 <int-e> korvo: what exactly is FNP? f(x) = y can be verified in polynomial time?
17:19:10 <int-e> (I can look it up if the answer is no)
17:19:35 <int-e> (I guess I could look it up regardless :-P)
17:19:54 <korvo> int-e: I think there's a couple equivalent formulations. I think of it as a generalization of ♯NP; it's like NP but all problems are valued in nats instead of Booleans.
17:21:32 <korvo> But we can take any countable domain, I think, so that we can have functions M -> {R} from markets to computable sets of computable reals. And that would formalize Nash equilibria, given a formalization of markets.
17:21:55 <int-e> hah, of course "FNP class" does not eliminate the "family nurse practitioner" false positive ;) ("complexity" did the trick)
17:23:14 <korvo> In this case, the part that's quick to verify is a function R × M -> 2 which checks that a particular market valuation is Nash by checking that each market participant doesn't have any better options; the part that's expensive is computing the history of the market's evolution.
17:24:06 <int-e> Hmm not sure I see the #NP (model counting) connection.
17:25:40 <korvo> Nash equilibria aren't unique; there's multiple possible histories which converge.
17:26:38 <int-e> I mean, FNP doesn't count.
17:26:57 <korvo> Oh, sure. It's more general than that.
17:27:37 <korvo> I mean, yes, I'm wrong; I'm just saying that I think of function problems as generalized counting of decision problems.
17:27:50 <int-e> I guess you can ask how many solutions there are and then it becomes #NP, more or less.
17:40:02 <b_jonas> /query hackeso
17:40:04 <b_jonas> uh
17:43:51 <b_jonas> https://complexityzoo.net/Complexity_Zoo:F#fnp doesn't seem to say that there's such a thing as FNP-completeness
17:51:58 <korvo> Aaronson omits many things, but yeah, it could well be the case that there's no such notion of completeness under reductions.
17:52:43 <b_jonas> do you know what kind of reduction this needs?
17:52:52 <korvo> Note that there's no such notion of PPAD-completeness either. It happens to be the case that the problem of finding Nash equilibria is complete for PPAD, but I'm not sure if there's a nice category PPADC of such problems or if Nash is a special case.
17:53:14 <b_jonas> different reductions can result in different notions of completness I think
17:53:39 <b_jonas> but maybe it's obvious in this case
17:53:39 <korvo> I imagine it's the same sort of reduction as in NP-completeness: a computable poly-time rewrite of the input problem. I'd guess that we also need a contravariant computable poly-time adapter for the output, so that we can transform the outputs from one problem to another too.
17:54:05 <korvo> Oh, yes, for sure. For example the category NPC is specifically about computable poly-time reductions.
17:56:40 <b_jonas> and like sometimes you want to allow multiple calls to an oracle
17:57:47 <int-e> korvo: you might have to poly-time manipulate the output too?
17:59:52 <b_jonas> ooh, this may be relevant: https://complexityzoo.net/Complexity_Zoo_References#dgp05
18:01:14 <b_jonas> C. Daskalakis, P. W. Goldberg, and C. H. Papadimitriou "The Complexity of Computing a Nash Equilibrium", SIAM J. Comput. 39(1):195-259, 2009. doi:10.1137/070699652 Originally appeared in STOC 2006, Author's website conference version "https://people.csail.mit.edu/costis/simplified.pdf" .
18:02:43 <int-e> yeah the PDF I linked above is a follow-up for that work (well, an earlier technical report version of it)
18:03:25 <korvo> int-e: Yeah. Like, imagine each function problem is a general arrow I -> O in some category. To transform it to X -> Y, we need both X -> I and also O -> Y, with the latter contravariant. This doesn't matter for NPC because everything is X -> 2 there.
