Small distributed projects?
There are several intresting puzzles/open problems on the internet that require some one to write some code and others to run it for a 12 months and the puzzle/open problem can be solved.
I would like to start/suggest such a forum where people can post such problems. If the problem is intresting, people can write some code and then others can run it. Most projects here will be small, basically finished in a few weeks. Here are a few examples of the kind of problems that can be attempted with very little computing power. http://www.mersenneforum.org/showthread.php?t=5866 http://www.mersenneforum.org/showthread.php?t=5630 http://www.mersenneforum.org/showthread.php?t=3474 Any thoughts Last fiddled with by Citrix on 20070811 at 04:51

Citrix,
wrt your third thread quoted... It's easy to prove a^xb^y = n [_any_ n] with slight modification of my FLT/Catalan reasoning. J

It obviously isn't a "small" project, but I just read in "Scientific America"(I think) that they would like to use computers to prove that there is no Sudoku puzzle with 16 numbers given that has a unique answer.
So far they've found one that has two unique answers, and they've proven it only takes 17 numbers to make a puzzle unique. But they've never found a unique puzzle with 16 numbers given. The article said it would take about 10,000 computer years to solve with present technology.

I don't think there are any easy solutions to this that can be found in 23 weeks on a few computers.

Aren't all solutions unique in themselves?

I think that the difficulty is a typographic spelling error. Rather than unique, I think that it should be spelled distinct, or something like that.

Since this thread has been resurrected by a link from another thread, I'd like to say, yes, it was a typographic error.

I'm surprised that there isn't a distributed project to solve the 7piece endgame problem (or the 6piece endgame problem with castling). [For chess.]

Is there a reference to this problem? Any code available?
