Board 8 > Puzzle contest: Winning board gets a $175 donation to their chosen charity.

(+) Yeah! (+)

so whats the puzzle

The puzzle is:

011100100011010
010010110010111
011011101011100
010110011110010
011101010001011
010011111001110

Additional information:
- The first line is arbitrary. The rest aren't.

- No significance to ASCII or anything else binary-related. You could replace the 1s and 0s with any other pair of characters and it would still make sense. Each line could be made shorter or longer, too.

- There are basically two rules that determine each line (or each character of each line). These rules rely on an assumption as well for them to make sense.

Your goal is to describe the rule that determines each line, and to write the next two lines in the sequence. The rules must be described in the most simplistic way possible -- describing a series of rules that emerges from the core set of rules won't cut it.

I've posted the solution online somewhere that it's verifiable that I posted it before creating the contest, so that if there's a question about whether or not an answer is good enough, I can refer to the actual solution that was written before the contest started. Final judgment rests with me, though.

Good luck!

I've done a "$X per post in this topic in the next 24 hours" topic on CE a couple times, but this time I thought it might be fun to make it a bit of a competition.

I'll be doing this on four boards: Current Events, Random Insanity, Poll of the Day, and Board 8. First board to post the solution wins a $175 donation in its name (if possible) to the charity that the board chooses (we'll have a voting topic afterwards). The other three boards will each get a $50 donation.

I'll post the puzzle in a later post so that all four boards see it within a minute of each other, given the 3-topics-per-15-minutes rule.

A little background on the puzzle: it's an original creation of mine that I came up with about five months ago. I've run it by several people and no one's solved it, but I don't actually think it's that hard.

I'll post hints every 24 hours to all four boards. I'll make the donations on August 1st.

(And to anyone wondering if this qualifies as spamming since there's an actual prize involved: I checked with a Lead, and since the prize is going to a charity, not an individual, it's fine.)

Raka, you'll need to describe how you arrived at that conclusion as well so if it is truly a wild guess it won't cut it. He wants us to show our work.

Doubt it, from what I see the number of 0s always go down to leave more place for 1s.

Yeah, what Angelo said.

--
Oh, I am one yet many.

How my solution works:

For each new character, look at the character immediately above and to the left of that character. If they are the same, use 0. If they are different, use 1. If you go off of the board, assume the character is 0.

In short:
0 0
? 0

1 1
? 0

1 0
? 1

0 1
? 1

Is the rule table. I believe this works, yes?

--
No amount of planning will ever replace dumb luck.

To add the logic, each number is determined by the values in the cells above and to the top-left of it. If the values above and to the top left are the same (or if there is no top-left cell at all), the cell value is 0, if they differ, the cell value is 1.

Hah, we won! Our ruleset is smaller than theirs!

--

Actually, no -- y'all win. CE posted an answer before, but the description wasn't good enough -- the puzzle specifically requested the two rules be posted in the most simple way possible, not a set of rules that emerges from the simple set.

Congrats :)

Alright, time to pick a charity.

I propose some sort of legal charity in the spirit of Phoenix Wright.

The charity of repaying people Icehawk conned into buying bad games

I recommend something toward Crohn's Disease since shadosneko has been diagnosed with it.

the ertyu show charity

Or maybe for Norway, if they're accepting charities.

EDIT: Jeff's idea is also great.

--

I like how he mentions how hard it is, no ones solved it, hints every 24 hours... and then two different people solve it within minutes.

I was going to suggest something about literacy in honor of ertyu, but yeah I think Crohns would be good

Clearly we need to give GameFAQs one of the Millennium Prize Problems cleverly disguised.

I agree with Crohns for shadosneko

Here's a children't charity for Crohn's:

Also I checked its rating on a charity-evaluation site and it has an A- grade, so it won't scam us.

Will not change sig unless the Sens win the Stanley Cup. Started 2/19/07

So, I've decided to actually give $175 on behalf of each board. My reasoning:
- CE, even though they didn't quite get the rules in the most succinct way possible, were first by a fair amount.
- Board 8 got the exact answer I was looking for.
- PotD and RI both came up with ways to describe the rule even more succinctly (XOR and binary addition, respectively).

Sorry, bank account. Yay, charity!

Ah man I solved this in like a minute... if only I had seen the topic earlier.

Anyways, this was p cool, Detroit is easily the best mod ever. Though it's kind of sad that he has to associate with all the other mods...

(10:17:09 PM) Ed Bellis: i think pac-man just keeps repeating, for instance
(10:17:26 PM) ertyu: ya well tell that to billy michtlle

I'd say the choice should weigh more to those who actually solved the puzzle. But as for my take, as someone who's family has people with Crohn's, I'd be all for giving money to the Crohn's and Colitis Foundation.
