In our efforts to increase security in CodeChef, we have restricted log-in into an account from only one system at a time. So, now if a user is already logged in from a system and she logs in again from a different system then she will be logged out from the previous one. The feature also holds for team login. So now one team can be logged in from only one system. If users face any issue, please send a mail to email@example.com.
The September 2010 Challenge is now over and it’s time to announce the results
But before we do that we shall like to share some Fun Facts about this contest:
Also we shall like to share with our fellow participants that there was an issue with the Servers problem this month. Our contestant Rajiv Kumar Aggarwal pointed this out soon after the contest. The test data was found to be not comprehensive and did allow a few incorrect submissions. For details please refer our comment on the wiki page. It was a glitch from our side and we sincerely apologize for the same to all our participants. We intend to work towards it and will try and ensure that it does not repeat

On the 24th of September we are running a 2.5 hours Warm Up Contest that is organized by Directi Go for Gold Initiative in collaboration with the Amritapuri regionals.
If there is anything that you would like to let us know then do comment on this blog post or send in an email to firstname.lastname@example.org
P.S. Winners will be contacted shortly.
Ladies and Gentlemen and Coders all around!
We are happy to announce “The First Warm-Up Contest” in preparation for the ACM ICPC Asia-Amritapuri Regionals.
What is this?
It is an online programming contest lasting 2.5 hours, along the lines of ACM International Collegiate Programming Contest.
When will this take place?
On 25th 24th September, 2010 from 20:00hrs to 22:30hrs IST.
Who is organizing this contest?
Amrita University in partnership with Directi as part of the Go for Gold Initiative.
Who should participate?
The contest is primarily intended for Indian student programmers, in teams of three, who plan to participate in the Oct. 17th ACM ICPC Asia-Amritapuri Online Contest.
However, others are free to participate as well.
Why should you participate?
The purpose of this contest is for Indian teams to familiarize themselves with participating in programming contests in general, and the ACM ICPC in particular.
What are the prizes?
The top two teams of three participants from India will have their registration fees for the ACM ICPC Asia-Amritapuri site waived if they qualify for the on-site contest in December!
You may add a coach and a reserve for the ICPC, but the original team composition must remain the same in order to receive the prize.
Visit the contest landing page to participate.
A few weeks ago, the Chef came to a realization: he needs to go on a diet. If you’ve seen him lately, you’ll know he’s practically bursting out of his clothes. So, in an effort to stop overloading on the code he loves to devour, he’s decided to start consuming only the highest quality code.
Only the top two finishers in India and internationally will be eligible for prizes.
We have a few reasons for making this change. For a while, our community has been telling us that CodeChef’s prize structure could do more to encourage people to do their best. We agree. With this new prize structure, we think there’s more incentive for people to put forth their best effort.
*Edit* Additionally, we will be re-allocating the saved resources to other project in the pipeline in the CodeChef Community. *Edit*
Prizes on CodeChef will now be as follows:
First Place Indian: 12000 INR- Second Place Indian: 8000 INR- First Place International Contestant: $400- Second Place International Contestant: $300
As always, please let us know what you think about this new structure. Your feedback is extremely valuable to us and helps us make CodeChef better.
Now get to cuttin the flab off your code!
Hey Guy’s, it’s time to disclose the Programmer of the Month for September, Anton Lunyov. He’s a 23 year old student from the Institute of Applied Mathematics and Mechanics of National Academy of Science of Ukraine. Anton has been participating on CodeChef since its inception in March 2009. He’s been extremely active in the past few month’s and been amongst the winners in many of our challenges. He also did exceedingly well in both the July Cook-Off and the August Cook-Off. Lets find out what our Programmer has to say.
Name: Anton Lunyov
Institute: Institute of Applied Mathematics and Mechanics of National Academy of Science of Ukraine
How/When did you start programming?
I started programming relatively late in 10-th grade after I enter the lyceum “Erudit”. I met many talented students there and wanted to be like them.
What do you do when you’re not programming?
I am a postgraduate student of my institute so I prepare my PhD thesis on spectral theory of differential operators, study scientific publications on different topics. Programming is just a hobby. I also like to play table tennis.
What do you like most about CodeChef?
I like to solve hard and challenging problems and compete with the world’s best programmers who participate here.
How many hours a day do you program?
Approximately 4-5 hours. But it depends on many things.
What is the secret to being a good programmer?
You should work hard and solve many problems per day from various online judges. But I guess without a deep knowledge in math you don’t have any chance of being a good programmer.
What are your plans for the future?
After I complete my PhD course I will continue the work of theoretical scientist in the field of operator theory but I guess I will still participate in many programming contests because I enjoy it very much.
The August 2010 CookOff, our second short contest format has come to a very exciting end. We’ve seen some superb competition in this contest with our first accepted solution coming in less than 5 minutes! Our five course meal has now been fully devoured and we hope you all enjoyed it!
First and foremost we would like to extend our appreciation and gratitude to our cooks for the night, Zac Friggstad and David Stolp, our extremely talented problem setter, tester and moderators. You guys did an awesome job!
For all those wondering what a cupcake baking tin is, here’s a picture.
And here’s a quote by Pieguy himself:
“A cupcake baking tin is a large piece of metal with a number of round indentations that can hold batter. When filled with batter and placed in an appropriately hot oven for an appropriate amount of time, a delicious treat emerges, which is cooled and often covered with frosting before serving (and makes a far better treat than muffins).
Of course, no picture could describe some of the non-planar monstrosities in the test cases.”
Here are the top 20 best performers of the August Cook-Off:
Take a look at the contest rankings here: http://www.codechef.com/rankings/COOK02
At the end of the contest the total submissions are as follows:
1) Arranging the Appetizers: 140 successful submissions
2) Backup Functions: 6 successful submissions
3) Baking Cupcakes: 6 successful submissions
4) Cleaning Up: 172 successful submissions
