Twelve-coin problem
code-golf combinatorics
Background
The twelve-coin problem is a classic balance puzzle commonly used in job interviews. The puzzle first appeared in 1945 and was posed to my father by my grandfather when he asked to marry my mother! In the puzzle there are twelve coins, o...
Books on a Shelf
code-golf sorting
I have some books and a bookshelf. I would like to put as many books on the shelf as possible but I have a rule. All dimensions of the books (height, width and depth) should form a non-decreasing sequence on the shelf.
This means every books has to be at leas...
Lets play a game of Meta tic-tac-toe!
This is a king-of-the-hill tournament of Meta tic-tac-toe. The rules of Meta tic-tac-toe are as follows:
All of the regular rules of tic-tac-toe apply.
There are nine boards arranged to make one master board. Like so:
0|1|2 || 0|1|2 || 0|1|2

@TheNumberOne On the Minecraft thing? It's up to you. Seems to say that what the OP wants to do is impossible (using only redstone and pistons), but there's a comment with a link to a video showing that it is possible (using other means, but still vanilla).
@randomra I think I might be getting close to optimal. There's still a little play in small numbers, but I don't see a way to get much better for anything over 20 or so.
If you write a brute that works in decent time, post it so I can compare :D
Thanks Martin! I'm glad to still be able to submit ungolfed entries to code golf contests!
I could have potentially rammed another car in the left lane had anyone been there.
I don't recall checking, but I assume that my brain may have checked for me, because if it didn't I would have knocked the car behind me into cross-street traffic or flipped it.
So, for giggles, I asked my Genetic programming framework to find a program that output the sequence 0, 1, 4, 9, 16, 25, 36... (n^2) and the solution it found in 6 generations was "Push the size of the stack onto the stack. Multiply it by the size of the stack before we did that, and output. Repeat." It kind of golfed its own code...
They're node trees. It's essentially a very small programming language that looks very similar to LISP. Here is the code it found, that gets output in a kind-of readable way: (*:0.000000 (StackSize:0.000000) (Push:0.000000 (StackSize:0.000000)))
Create a program or function that, given a postfix expression, converts it to the simplest equivalent expression. The expression may contain real numbers, floating variables denoted a to z, and the basic arithmetic operators +-*/^.
Two expressions are equivalent if they produce the same result f...
with a python program how can you solve that task (i.e. multiline input with unknown number of lines)? my ideas: sys.stdin.read() or something like try while 1: input() catch EOFError
That latest moment when my finger is on the enter key is when I have put in more effort than I ever will put into that message. By waiting until that latest moment, they have caused me to waste the most effort. Thus, that is when I am ninja'd the hardest.
If they give me, say, a five minute lead, then I waste no effort at all and do not feel ninja'd. In that case, I would say they ninja'd me softly.
Well, edits after the fact don't count. If I get my message in first, I cannot be ninja'd at that point, and so no further effort can be wasted.
If I get my message in second, then I hopefully am paying attention after I press enter and will waste no more effort. Either way, no more wasted effort.
Another proof that I am right: If you hit a tennis ball at me and it gets to me 30 seconds later, then you did not hit it hard. If I am instantly blown away by your tennis ball, then you hit it hard. We have demonstrated that the shorter the time between your opponent taking an action and you taking an action, the harder it was hit. Same for chat.
> At the heart of his theories lies the idea that a secret group of reptilian humanoids called the Babylonian Brotherhood (including George W. Bush, Queen Elizabeth II, Kris Kristofferson and Boxcar Willie) controls humanity, and that many prominent figures are reptilian. He further proposes that the Moon is an artificial construct — "probably a hollowed-out planetoid" — from which the reptilians broadcast an "artificial sense of self and the world" that humans mistakenly perceive as reality.
Maybe after being on our planet so long, you've began sympathizing with our people. You're suffering from some internal conflict about whether or not you should tell us, so you keep changing your mind before you reveal anything.
@BrainSteel If Rainbolt's hypothesis is correct (IIRC, that the replacement was done around the time of the avatar change), then I haven't been here very long. Certainly not long enough to start empathizing with weak-minded humans.
I think I'm supposed to say something about human capacity to love, then shoot you in the face, and then provide a corny tag line. But maybe we could deviate from that and just live in harmony?
