2026-02-20 19:12:59 +0100 <dutchie> "The dual notion is often called antitone, anti-monotone, or order-reversing"
2026-02-20 19:12:53 +0100 <dutchie> wikipedia also says "order-reversing"

2026-02-20 19:11:51 +0100 <EvanR> reversing that would be interesting xD
2026-02-20 19:11:06 +0100 <fgarcia> reverse kind of works. or maybe not
2026-02-20 19:11:05 +0100 <n0w0n> heh, oh analysis my analysis
2026-02-20 19:10:42 +0100 <EvanR> a monotone function maps more defined inputs to more defined outputs
2026-02-20 19:10:11 +0100 <EvanR> are we talking about semantics i.e. definedness
2026-02-20 19:10:06 +0100 <Leary> It's a phrasing that's more pertinent to sequences, yes, but nothing will stop mathematicians from overloading, so they use it for functions too.
2026-02-20 19:09:31 +0100 <c_wraith> I would say "monotonically decreasing" as a description of a sequence, but "antitone" is a description of a function. *shrug*. It's not too important.

2026-02-20 19:08:26 +0100 <EvanR> if monotone is supposed to be not decreasing just say that?
2026-02-20 19:08:20 +0100 <haskellbridge> <ijouw> But isn't that describing the values themselves?
2026-02-20 19:08:11 +0100 <Leary> But antitone is cool too.

2026-02-20 19:07:40 +0100 <Leary> People usually just say (monotone/monotonically) decreasing.
2026-02-20 19:06:42 +0100 <haskellbridge> <ijouw> I wrote that as answer to anti-monotone
2026-02-20 19:06:13 +0100 <haskellbridge> <ijouw> Seems consistent
2026-02-20 19:06:09 +0100 <c_wraith> oh, I guess "antitone" is acceptable as well. that's better
2026-02-20 19:05:45 +0100 <c_wraith> but it's awkward as heck
2026-02-20 19:05:39 +0100 <c_wraith> well, there's anti-monotone
2026-02-20 19:05:20 +0100 <haskellbridge> <ijouw> Is there a word for a change (analogue to monotonic), when it reverses ordering?
2026-02-20 19:04:57 +0100 <c_wraith> For the specific question being asked, that's not relevant
2026-02-20 19:04:51 +0100 <EvanR> e.g. comparing bytestrings for ordering can be faster than hashing depending on the length and type of hash
2026-02-20 19:04:21 +0100 <EvanR> it might not be faster depending on how expensive hashing is
2026-02-20 19:04:14 +0100 <c_wraith> Leary: I tend to forget about that too
2026-02-20 19:02:31 +0100 <haskellbridge> <ijouw> So it trades space efficiency for faster lookup, got it

2026-02-20 18:57:28 +0100 <Leary> Let's make that a > 0, I forgot non-positive numbers exist.
2026-02-20 18:57:26 +0100 <c_wraith> the HAMT it's based on has a much higher branching factor
2026-02-20 18:57:14 +0100 <c_wraith> fewer comparisons
2026-02-20 18:56:56 +0100 <haskellbridge> <ijouw> What advantage does HashSet a have over Set (Hashed a) where Ord Hashed compares the hash?
