Yet another nice forum:

btw, AOPS forum [url]http://www.artofproblemsolving.com/Forum/index.php[/url] seems to coincide with MathLinks forum [url]http://www.mathlinks.ro/Forum/index.php[/url]

Today I've solved the Torricelli triangle problem so now I'm 100% genius on [URL="http://projecteuler.net"]http://projecteuler.net[/URL]
Currently there are 159 math problems on the page.

you should be 100% genious everywhere...
as to me, I'm only 13% geniuos since I just created the account some hours ago and put only 20 solutions so far (but I think with quite concise gp code - even if it cannot rivalise with J (or Berkeley Logo(?))...
but in my defense, I could say that 13 is my favourite number so maybe I won't put any more solutions, anyway... (unless a rising # problems would make my % go below 13).

In spite of my plan to stick to my 13% I could not resist in having a look at another one and I'm a bit deceived since
a) it made me loose my "13"
b) like all preceding ones, I also solved it by a (more or less) "brute force" PARI 2-liner (well to post it I added indentation & several line breaks) doing the job in 4 seconds (ok, by at least an order of magnitude the slowest so far...)
But I regret that not very much mathematical thinking was needed in my solutions so far (IIRC), at best a little bit of creativity in programming could be used to give a "concise gem" solution.
(ok, you might irrefutably blame me for chosing the questions according to that criterion...)

Congrats on being the first to have solved the latest problem (#168) !

30% Project Euler Genius...
 

Not that good yet but it is a milestone I didn't expect to reach this quickly (about 3 weeks)... maybe I need to get a real life :wink:
