OJ Board

I will take a look. Thank You!

I see. Are you in Texas now? Wow!

Is the OJ site getting quite slow on serving problem lists now, or is it just my internet connection? I remember when the site was first moved to the new machines, it was lightning fast, now it's like even slower than before moving to the new machine.... Can admins or frequent users comment on this ...

Is there a way to prevent those spams?

There can't be rounding issues because everything is an integer. Quad Tree works, yes. I am sure there is another method since the author emphasized that no 3 points are co-linear, which I am still not sure why is important. At any rate, the judge data is bad for this problem until the administrator...

For java submissions, I believe you need to use class Main, since that is what is used at command prompt when running the program.

I asked for this in the ICPC Live Archive and it turned out to be a great feature. Can we have the problem name shown as one additional column (or appended after problem ID number) on the user statistics page? http://icpcres.ecs.baylor.edu/onlinejudge/index.php?option=onlinejudge&Itemid=15 Of co...

There is a problem with the links. You may solve this by removing the "com_" sub-string in the URL.

As far as I know, there is no such capability implemented yet. May be in the future.
