Ok, compressor has been fixed now. Thanks to Rujia Liu, ACRush and Igor.

Igor,
I am confused - what is the only thing more important than solving problem...? Job or Wife/Girlfriend .

This new rejudge is still not final. This one is judged based on the other solution. Still its correctness is not verified, but many elite people's output has matched this one as well.

Things are in place with Rujia Liu, Yiming Li and Igor for their verdict.

Don't try to count how many point each triangle contains.

Select a point and try to determine how many triangles it is within.

Oh. Is it really so? The judge output file that I sent to UVa has a blank line after the last case. (I still have the file in hand.) Admins please have a look. Thanks.


And I don't mind if the problem description is changed to fit the current judge output, if you think this is more fair.

Congratulations to the 11 contestants/teams that solved all 6 tasks in contest time!!

We hope everyone enjoyed the contest, and we would also like to hear your comments~

We receive much less clarification requests than last year, which is good, since that means our tasks were not full of flaws ...

I hope they will try the option of avoiding US.

Often the contest organizers fail to emphasize the importance of all teams being present. And I have not seen public announcement (May be I have missed) when any team fails to come due to visa problem in ICPC.

That is why I think the Shanghai ...

i have heard they will be in orlando.

Yikes! Getting US Visa is not easy for some countries :(. But of course for most it is a great venue.

Sometimes in the name of globalization some venues are chosen which are not easy to reach. For example the IMO venue was perhaps slovenia this year which ...

I must say that the picture site is very badly organized. Searching is very poor. And lastly I am upset because I could not find my name there although I was in the guest list.

A few minutes (some times a few hours) after the contest is over you can try the problems of the contests at the UVa online judge, following the link 'Browse Problems' to the last available volume of the Problem Contests category.

Remember our new server is http://uva.onlinejudge.org .

Thanks everyone.

You may have noticed that the concerning images have been removed from the problem statements, and I have mailed the copyright holders. Hopefully they'll reply within a few days.

Let us just leave this topic as it is now until we receive the replies, shall we? :wink:

Sorry again ...

Sorry again.

I have written a mail to site admin about this matter. Let us wait quietly while they are fixing things. Putting new posts here does no good, since the site admins do not read this forum often. (I am not a site admin.)

P.S. Next time if you find problems in contest pages, please ...

Thanks for your post.

The quotation you have is directed to site admin, not to contestants. We include this line simply because we know nothing about the copyright laws in Spain. The site admin has the right to make any changes to the webpages as they want.

I recall the following pages:

Of course there are people supporting the system, but we are having many contests last days and doing some changes. The 20th september the judge went down about 13:30 UTC and people continuous submitting and trying to see its status, as it's normal. Then the internal mail server went also down and ...

This problem is not original. You will get detailed discussion at the book:
How to solve it: Modern Huristics by David B. Fogel and Michalewicz page 274.

So I knew the math soln but did not use it considering it a programming contest . And Kisman's alternate solution was based on math.

If you managed to get the n^4 algo to run that fast, I guess AC is ok. In any case, it's very hard to forsee all possible pruning conditions. I would have wanted to increase n to 100 or 200, except that the I/O part becomes too intensive then which ain't good.

I wasn't aware that the time limit ...
