Congratulation to the winning team HoChockiGon and thanks to all the participants.

30 teams can participate in the finals, but the first 50 teams will be invited as usual, details will be in e-mail (see FAQ).

All materials and write-ups will be in the archive. (it will take a few days to collect so check back and if you have a writeup, solution or criticism then drop us a link on the #challenge24 irc channel and we will publish it on the EC writeup page).

If you haven't yet filled in the post-EC poll then log into your team page and please do so (this optional feed-back is useful for us).

Pre-EC on this weekend

2014-01-28

As in previous years, there will be a "demo round" one week before the EC, called the Pre-EC. This gives you the opportunity to test our submission interface and the evaluation process, and lets us check our infrastructure. You can also use the Pre-EC's problems to practice handling the file formats you may have to deal with during the EC. We think it's highly advisable to try the Pre-EC.

The Pre-EC is 12 hours long to accommodate various timezones and schedules, but it doesn't typically require more than a couple of hours to solve the tasks.

Hotel

2014-01-28

If you've been prevented from entering the competition before by the costs of finding a hotel room in Budapest, we have good news: we will provide accommodation in a hotel to every team in the finals, free of cost. Rooms are available between May 1st and May 5th - so you'll have some time to do some sight-seeing in Budapest, if you'd like. As in past years, there will be some common activities, with optional participation.

For team coaches, significant others, unofficial teams etc., we can offer rooms in the same hotel for 22 EUR/night/person. After the EC, there will be a web survey where the winning teams can request accommodation.

Share your Challenge24 experience!

Have you got a good Challenge24 story? Would you like to share it? Like this (from 2012):

Do not try to solve any task by hand. There's always a trick in the background (we tried to submit the number of triangles by hand in the first 2 minutes, but of course, there was a trick involved, so we earned a nice -5 points just after the contest started).
