@Adám that won't help much when you transpose eta to eat or tea ;-)
 
@Neil That's when you need an AI to guess the "right" word...
 
@Bubbler but there's still a chance of getting the wrong word
The "right" word is completely subjective
Is it not?
But I've probably missed a joke here
 
Of course an AI can't be 100% correct
so it's not a good task for, say code golf, but it's still an interesting problem in general

Essentially, the solution is find the best solutions in each language to each challenge, and then treat each pair of such solutions as a match between those two languages, with the winner being the shorter submi...

Q: Extract words with clue numbers in a Crossword puzzle

BubblerRelated: Read a crossword Task Given a completed Crossword puzzle, extract the words in it with their respective clue numbers, with "across" (horizontal) and "down" (vertical) words grouped and ordered like a real crossword puzzle. The words are numbered in the row-major order of their first l...

@Adám Is there any reason for Dyalog APL to deviate on ¯4○Y from other APLs (which define it as simply (¯1+Y*2)*0.5)?
After some more experiment, it actually looks like J's doc is imprecise.
 
5:04 AM
Whoops, wrong room.
 
@Bubbler Which doc?
 
@Adám Both J doc and NuVoc.
 
"Sqrt (Sqr y)-1" and "sqrt (_1+(y^2))" are the same as (¯1+Y*2)*0.5, no?
 
It actually computes sinh arccosh y, which is sometimes the negative of that.
 
5:28 AM
@Bubbler Huh, so almost everyone neglected to check the documentation when they added complex numbers. Only NARS2000 gets it right: (R+1)×√(R-1)÷(R+1)
 
Dyalog one is also fine. It uses that exact formula, and manually fills the gap at -1 (because that formula hits division by zero).
 
No, I don't mean that the formula they use is wrong, only that the previously correct documentation ceased to be correct when complex numbers were added.
 
5:44 AM
@Bubbler How did I manage to get it right in APLcart
 
 
6:08 AM
@Bubbler So ¯4○ is sinh arcosh and 4○ is cosh arsinh. Are there similar formulations for ¯8○ and 8○ and 0○?
 
6:31 AM
@Adám Yes, 0○ is cos arcsin or sin arccos.
 
@Adám I've got no idea for 8○. 0○ is correct.
 
@Bubbler There aren't any for ¯8○ and 8○. I just wrote a program to search for it.
 
@Adám Btw, didn't you realize this chatroom isn't the Orchard...?
 
I did, but nobody is here anyway.
@Bubbler Might interest you. Not beautiful code, but did the trick.

@Neil Jelly is admittedly terrible. Jelly is even worse however, since I couldn't even program in it.
 
@Λ̸̸ In order to program in Jelly, you need more than just training, you need Jelly Hypertraining™!
 
I never understood (and will never understand) how are chains evaluated, so when I have to program in Jelly, I simply reorder characters until it works and also try to add random quicks (those with the complicated descriptions) in random places. It usually works in the end.

Hey guys I made one trivial code-golf challenge and one more serious related fastest-code. Since the explanation of the first it's fully contained in the second, can I merge them in one single post then accepting 2 different categories of answers? Or should I keep them separated?

@DomenicoModica Keep them separated. One requirement for a challenge is that we must be able to decide on a single winner based on the criterion.
