Hi all!

Unknown language round #1 was up, 21st of February and now we're going to hold yet another Unknown language round.

It will be the usual ACM-ICPC unrated contest , so there is no hacking! The only feature - you will be able to submit problems using the only one, not very popular language. What? It's a secret! And I expect you'll have to learn the language at the time of contest since the used language will be a secret until ~1 minute before the start of contest.

Problem setters of this round are Alireza Farhadi, Saeed Ilchi, Sajjad Ghahramanpour, Zahra Rohanifar and Me. We are extremely grateful to Mike Mirzayanov and Artem Rakhov.

Number of problems will be more than usual and the problems concentrate on coding abilities rather than algorithmic view and problem solving techniques.

UPD:The contest is over

Congratulations to the top 3 winners who solved all problems:

CodeFest'11, the annual online international coding festival of Computer Engineering Society IT-BHU, presents Manthan - the algorithm intensive programming contest. The name Manthan or मंथन has been taken from the Hindi language and means Brainstorming.

The contest aims to provide a platform for programmers round the globe to showcase their problem-solving and programming skills. Most problems of the event will be real life computing problems where coders will be required to prune existing standard algorithms to find the solution for the domain specific application of the algorithm.

We are proud to have Codeforces as our partner for Manthan 2011. The Contest will be hosted on Codeforces and will follow the rules similar to that of Codeforces Beta Round.

• The main event is scheduled on March 13 at 2200 Hrs IST (UTC+5:30)
• Rules of contest similar to Codeforces Beta Rounds.
• The Contest will be of 3 hours consisting of 5-6 problems.
• Programing languages allowed: C, C++ , Pascal, Java, C#, Python, Ruby, PHP, F# and Haskell.
Open to all, students as well as professionals.
Declaration of Results on March 16 at 1800 Hrs IST.

The contest duration changed to be 3 hours. Good luck!

Last night I don’t want to sleep, so – I was working. I reread my old post "Contribution 2.0" (in Russian) and decided to implement some ideas. Taking into account the comments that everyone (no matter the color nor the position in the contribution) has the right to express their opinions in the form of pluses or minuses, I did not restrict users the opportunity to express opinion.

On the other hand, the rules of contribution changing depending on your votes have modified. Since we have already appeared bots, trolls and other vermin, I will not reveal details, but note that:

• Contribution may change after some time after the processing of your vote - it is normal.
• Not all your votes may be taken into account when calculating the contribution changing - this is also normal, we will defend ourselves from dirty tricks.
• contribution slightly scaled - the numbers got bigger. Maybe it's nicer?

Just want to say that the bots usage, following the principles of "blood feuds," etc. serve as a reason for your disqualification. Do not tempt fate.

Soon, the problems coordinator, the user RAD will leave official lists of both contributions and rated, as he is active member of the Codeforces team.

I wish you high contribution
