Hi everyone!

The ACM ICPC season is in full swing, and the Northwestern European Regional Contest (NWERC) is not so far away from now. This is why the University of Cambridge held a selection contest for its 9 teams to determine the best (two or more) teams that will compete for a place in the world finals. In the end, the following teams took the top 5 places in order:

1. Fin! IRO (pooya_, bogdan2412, VladGavrila)
2. Beuler (borisgrubic, lm497, dcevid)
3. Rooftop Cornflakes (eduardische, Chortos-2, Gullesnuffs)
4. Zrakomlati (PetarV, mbucic4, dsobot)
5. CRTCM (Voro94, Andip, hadesgames)

Congratulations!

The competition was held on the CodeForces platform and prepared by me and MikeMirzayanov. It was organized by University of Cambridge lecturer Dr Andrew Rice, eduardische Chortos-2 and the coach of the Latvian IOI team Sergey Melnik. The contest itself used the problem set of the Southern Subregional (NEERC) ACM ICPC quarterfinal 2013. Yes, the same quarterfinal whose online version will be held as a contest in the Codeforces gym on 27 October. ;] You may have just thought that you missed something unusual on CF, but nothing of the kind! The contest was run using a (still secret) future Codeforces tool in test mode; the name is groups.

This functionality will give the opportunity to hold contests only for a specific set of participants and spectators. A manager of the group adds users to the group and chooses their access restriction types. Only group members can participate in contests within this group, as well as observe their results. As you can see, groups are well-fit for on-site contests of various sorts. Indeed, this time we used the test version of this tool exactly for this purpose. Special thanks to MikeMirzayanov for the opportunity to try this new functionality! Now I'll leave a couple of teaser pictures for you: ;]

In conclusion, a few words about the selection itself. The number of problems solved by the top 5 teams is 10, 9, 8, 7, 6, which is a serious claim from the University of Cambridge compared to the results of the on-site of the same quarterfinal. ;] During the contest, the top three teams were engaged in an intense struggle for the first two places, but in the middle of the contest Fin! IRO made their way to the top and held a stable lead with many solved problems. Teams Beuler and Rooftop Cornflakes kept pace almost until the end of the contest, until the former solved a whole two problems in the last hour. The latter also then managed to solve two problems in the last hour, but Beuler got an accepted submission for problem D at 4:47 and secured the 2nd place, while Rooftop Cornflakes got the 3rd. The full results of the teams from Cambridge will be embedded into the results of the gym contest on the problems from the Southern (NEERC) quarterfinal.

Hello,

Did you already notice that this Sunday it will be Internet-version of 2013-2014 ACM-ICPC, NEERC, Southern Subregional Contest? It will start on 07:00 (UTC).

The contest will be held in Gym. I invite teams mostly because the contest was designed as a team contest.

I'm sure this contest is a great way to train before coming regional (or subregional for some of you) ACM-ICPC contest.

On Satudray, Oct 12, at 12:00 PM another 5-hour contest in Codeforces Gym will be held. It's the second time we prepare qualification contest for Samara SAU teams to determine who deserves to participate in Southern Subregional Contest in Saratov (the previous such contest can be found here).

Maybe you know that team Teddy Bears is no longer able to take part in ACM ICPC. It resulted in renaming and renumbering the teams in the university. You have an unique opportunity to defeat new first team of Samara SAU and show them at what place they can finish in Subregional Contest. Don't miss this chance!

Contest is over. Now you can just solve the problems or take part in the virtual contest.

Many thanks to Xellos who made a tutorial.
