"Big conjunction" and "big disjunction." 07:19:40 You could do a "big xor"-type quantifier but only over a finite number of values. True when an odd number of cases is true. Material implication is non-associative so it wouldn't be much use. 07:23:59 Good old upside-down E. 07:25:26 Lives a secret double life as "Mirrored over the y axis E" 07:40:27 -!- Sgeo has quit (Read error: Connection reset by peer). 07:47:07 -!- tromp has joined. 08:26:28 would "exactly one of" be a more useful generalisation? 08:26:53 wouldn't be just folding with xor though I suppose 08:55:26 HireFly 08:56:00 I'd expect it to behave like an xor clause in SAT solvers. 08:56:08 Though I guess really there's just one solver with xor clauses. 08:56:46 "exactly one" is a standard thing, anyway, it's just called "exists unique". 09:07:07 I think to have an operation which folds to uniqueness quantification you'd need to take a visit to 3-level logic. 09:08:20 3-level? You mean 3 nested quantifiers? 09:08:43 I mean logic with 3 truth values rather than 2. I'm sure there are other ways to do it but this is the most straightforward way I can think of. 09:08:59 Oh, "folds to". 09:10:30 truth values {f, t, T}, but with inputs strictly over {f, t}. f\$f = f, f\$t = T, t\$t = f, T\$f = T, T\$t = f, with \$ commutative. If you fold \$ over arbitrarily many inputs then collapse {t, T}, you get uniqueness quantification. 09:24:22 -!- tromp has quit (Quit: My iMac has gone to sleep. ZZZzzz…). 09:28:06 Slightly more elegant version. data Counter = None | One | Many; and count :: Counter -> Bool -> Counter. count x false = x; count None true = One; count One true = Many; count Many true = Many. `foldl count None` takes your list and outputs Counter. 09:28:55 So if I've done it right (==One) . (foldl count None) is a uniqueness quantifier. 09:29:30 at least write it lazy like count Many _ = Many as the first definition, so you don't have to continue on a list after finding two trues 09:30:04 Right. Somewhere in there I went from pure math to Haskell. 09:41:40 though that no longer strictly counts as a three-level logic solution since the count function takes two different types of input. 09:42:32 I'm not referencing any specific mathematical definitions there; just vibes. 09:42:50 -!- hppavilion[1] has quit (Quit: Leaving). 09:51:53 [[Special:Log/newusers]] create * Quadruplay * New user account 09:54:31 [[Esolang:Introduce yourself]] https://esolangs.org/w/index.php?diff=124336&oldid=124279 * Quadruplay * (+153) /* Introductions */ 10:19:45 [[Electra]] https://esolangs.org/w/index.php?diff=124337&oldid=124333 * DolphyWind * (+29) 10:33:42 -!- amby has joined. 10:43:26 -!- tromp has joined. 11:25:14 [[Trintercal]] N https://esolangs.org/w/index.php?oldid=124338 * B jonas * (+25) Redirected page to [[TriINTERCAL]] 11:39:55 -!- ajal has joined. 11:40:43 -!- amby has quit (Ping timeout: 246 seconds). 11:44:53 -!- ajal has quit (Ping timeout: 240 seconds). 12:36:06 [[Talk:Sign]] N https://esolangs.org/w/index.php?oldid=124339 * Xyzzy * (+93) Created page with "Infinite loop test: ~~~~" 12:40:49 -!- tromp has quit (Quit: My iMac has gone to sleep.
