Later you'll be introduced to the rules of the Codeforces contests, which differ from those of ACM-ICPC, TopCoder, GCJ, and I hope they'll bring some difference to the world of programming competitions. Most of the official competitions will be carried out according to these rules, though there will be more traditional contests. For example, Codeforces Beta Round #1 will be carried out according to the familiar ACM-ICPC rules. For some time testing will be based on Windows, but things might change in future, fortunately, the system supports testing on different platforms, even within one contest.
At the present time the system is configured to support the following programming languages (the compilation and/or the launching line is shown for each language):
It is not guaranteed that all the problems will have solutions in all the given languages (it's especially about the scripting ones). Probably, I'll later introduce equalizing coefficients for the working time for some languages. A "plus" next to the version name means that the testing system can use older versions. If you have suggestions about the possible ways to change the compilation or the launching line, write about them in your commentaries.
It should be mentioned that apart from standard verdicts, you can get "Denial of judgement", which usually means that your solution can't be launched, or it has unexpectedly failed. For example, is the Delphi array is too big, the compiler compiles the code, but the result will be the incorrect win32 exe-file. Solutions with the verdicts like "Compilation failed", "Denial of judgement", "Judgement failed" will be ignored while summing the results.
Moreover, pay attention, please, that the problems will be given in English as well as in Russian.
That's it, see you at Codeforces Beta Round#1.
UPD: GCC compiler has been added.
UPD 2: Added Haskell and F#.
UPD 3.2: Actual compiler versions are
I will briefly enumerate the changes at Codeforces:
The results are announced - thanks to Ivan Romanov for being so quick. Thanks to everyone who supported us and followed the contest events. My apologies the system break-down, but if everything was stable in Codeforces, I wouldn't have called it beta. Unfortunately, I had no Internet during the day.
The third day was marked by rises and falls of Harbin in our eyes. Everything started with the opening ceremony - it was badly organized, protracted and boring. Right before the opening ceremony the audience went to the assembly hall of the Harbin Engineering University, but the participants were less privileged and had to suffer. We were all gathered in a long basement room, we had to form a line according to predetermined numbers, and wait. As you know, 103 teams take part in the finals, so, about 450 people (coaches and volunteers included) packed into that basement. It was stuffy and crowded there. The Russian teams demonstrated their inherent quick-wittedness, they decided not to stand in the crowd, and moved closer to the entrance, it was cooler and there was more room there.
Finally, to solemn music (be careful, phonogram!) the teams one by one climbed the stage, took pictures and went down to join the audience. As after that according to the program some outdoor activities were planned, many participants had prepared sensibly beforehand, they had put on the presented warm trousers, sweaters, etc. With such a "formal" look they got to the opening ceremony and the shoot. My standing ovation.
The second day we spent sightseeing - we went to the excursions organized by the host country, some places we visited on our own.
In the morning we had some free time, and we went to the local Arbat (or Kirov Avenue, as you wish). Actually, when we walked not far away from the hotel, we found out that we vaguely knew how to get back. But still we didn't want to go back, that's why we went on moving away, guided by little information we had. It was really cold - but we were well-prepared. I put on a down-filled coat, that we'd got on the first day, over my proper one, foe example. Vova put on the presented trousers over his own jeans, and seemed happy. The parts that got cold were our faces.
On our way to that avenue we asked for the directions many times. The problem was that we didn't remember its name. 80% of passers-by said they didn't speak English, 20% said they did, but it was the only thing they could say in English. Finally, using the international language of gestures, we got the direction and found the avenue. Personally I was disappointed, there was nothing to look at there. Of course, it was interesting to walk past old buildings, but we had no desire to "Russian goods" shops. They sold home-made vodka, chocolate called "Russian fir (pets)" (they meant "pelts"), and other goods of doubtful quality.
Everyone got a set of warm clothes. The hats in the photo looked more like scarves at closer inspection. Moreover, we got a set of mustard plasters, which are recommended to be worn under your clothes to keep the body warm.
The Indian team got very excited, when I asked them how popular the TV series The Big Bang Theory is in India.
