Solve the Catalan Conjecture! Let's say we have a number n, if it's even n = 2*n and if it's odd n = 3*n+1 For example: 10 -> 5 -> 16 -> 8 -> 4 -> 2 -> 1 you stop when you reach one because it will loop forever after that: 1 -> 4 -> 2 -> 1 Input any natural number. Your code can be a f...

@Deadcode The yarn on a 3x3 cube starts at the center, spirals around the top face, then spirals across the outer faces down to the bottom face, until it reaches (0,0,-1), then goes to (0,0,-2)

Okay. I considered that too.

But it's much less like a ball of yarn.

True

I don't really know what to call it

Q: If there is "a winner for every language" in a code golf challenge, does competitiveness matter?

2:32 AM

@lirtosiast Would it be acceptable if it covered faces using a back-and-forth snake pattern instead of a spiral? Its Chebyshev distance would still be nondecreasing.

The consistent attitude with regard to the golf language situation is that for every challenge, each language is a category, and subsequently there is a 'winner' for each language. This is also a very very popular opinion with regard to the new user experience. There is a problem with this idea...

I suddenly just got +100 reputation for an association bonus

What is an association bonus?

Veskah

Basically you haven't been a rude dude so you get to bypass the need to grind rep for basic features on new SEs

Like commenting needs either 50 or 75 rep, I forget which

Q: What is the association bonus?

I was just awarded +100 reputation on all of my Stack Exchange accounts. What is this bonus for? It simply says "Association Bonus" on my reputation overview. Return to FAQ index

TL;DR: when you reach 200 rep on any site on the network, all your accounts on all sites get +100, because reaching 200 rep is a decent sign that you know enough about how SE works to not need the training wheels of <100 rep on any site

@Deadcode Of course. There are other solutions too, and I want part of the challenge to find the golfiest one.

Q: Remove [windows-system] tag

windows-system was just created for a question put on hold as unclear, and I see no reason to have OS-specific tags. Indeed there are none for any other OSs.

@Anush Hello.

I was thinking of a challenge where you have to say the number of moves to mate for any 3 piece chess endgame

or output that it's not a forced mate

does that sound reasonable?

I suppose it has to be a restricted time code-golf challenge to make any sense

do you personally know of a good way to solve this problem, without brute forcing?

@primo The challenge is not really to find out the answers, which I think is easy, but to encode them in small space

three pieces is just two kings plus one other piece

oh, i was thinking 3 pieces per player

@primo that's much harder!

those databases exist and it would be great to be able to encode them in less space

but not as a first challenge :)

i think the problem should be simple enough that even brute force should be viable

11:37 AM

there is a challenge where the point is for the code to find the answer

there is another challenge, the one I had in mnid, where the answers are precomputed and the challenge is to make the code including the answers as small as possible

a code-golf challenge

queue=[{state = <input>, depth = 0}]
while queue not empty:
  state, depth = queue.next()
  if state is checkmate: print(depth) and exit()
  foreach move in validmoves():
    newstate = state.apply(move)
    queue.add({newstate, depth+1})

i think that could be made fairly short
