The March 2010 Cook-off has ended. All top 10 participants have solved 4 problems, but surprisingly the 2 people who solved the 5th problem aren’t in the winnings!
We would love to thank our fantastic cooks this night, Zac Friggstad and Anton Lunyov, our awesome problem setter, tester and moderators.
Here are the top 10 best performers of the March 2011 Cook-Off:

Check out the contest problem editorials here.
If there is anything you would like to let us know regarding this contest then do let us know by either commenting below this blog post or by sending in an email to email@example.com.
P.S. Winners of the contest will be contacted on Monday/Tuesday.
The March Challenge 2011 is over and we are sorry for this delayed announcement.
The contest was marred in between and we faced a downtime for a period of more than 30 hours! The Judge we use on CodeChef is maintained in Poland. While the ISP, on which the Judge resides, was performing some maintenance work it was unfortunate that some backup cables were damaged, which caused the breakdown of the Judge servers. It was a rare occurrence that such major downtime was faced. The server team worked for all this while waiting for the electricity to be restored and get the Judge servers up and running as quickly as they can ensuring that no data was lost. We apologies for the inconvenience caused and also thank you for being patient with us and coming back to participate on the extended day.
Now the good news.
Before we announce the results, a special mention of the people who made it possible:
Zac Friggstad, Ivan Mistranu, Ashar Fuadi, AnhDQ, Tomaz Hocevar were the problem setters while David Stolp was the diligent tester of this month’s contest.
Lets look at some Statistics and then move on to see the final winners list.
|Length of Contest||Unique Visitors||Unique Participants||Total Number of Submissions||User who have solved at least one problem|
|Country||Total Participants||Average Score per User|
|Rest of World||246||0.66|
Winners list for the March 2011 Contest:
01. rudradevbasak (winner of prize money Rs. 12000)
02. utkarsh_lath (winner of prize money Rs. 8000)
10. Anuj Arora
Congratulations to all.
If you haven’t yet checked out the editorials of the problems to this month’s contest please do so here.
We are running a 2.5 hours Cook-Off that is scheduled for 20th March 2011 at 21:30 IST
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

Welcome to the 2010 – 2011 Programmer of the Year blog post.
CodeChef has completed 2 years now and we’d like to thank everyone for making it so successful. Someone that we would love to highlight this month is Zac Friggstad for his invaluable and continuous contribution to CodeChef as a Problem Setter, Tester and Moderator.
Zac has been on our problem setting panel since the beginning of last year and has been doing a fantastic job for us at CodeChef.
Lets take a look at his contributions in all our contest last year:
Since April 2010, Zac has been part of our contest moderation panel every single month. In this duration he has acted as a problem tester 4 times, set 8 challenge problems and 12 other long contests problems and has been the author for our CookOffs 3 times already!
Zac has been our specialist in setting the Challenge problem for a while now, and though he’s never participated in our programming contests, we would like to bestow the title of Programmer of the Year for 2010-2011. On behalf of CodeChef, we’d like to thank Zac, for all the contributions he has made to the programming community so far and hope he continues to do so. :)
Here’s more from the programmer of the Year himself:
Name: Zachary Friggstad
Institute: The University of Alberta
Brief introduction about yourself:
I’m currently in the 4th year of my PhD studies at the U of Alberta where I study the theory behind efficient algorithms for combinatorial optimization problems. Most of the problems I study are NP-hard so I focus mainly on approximation algorithms. I also enjoy pure mathematics; I almost chose to do my graduate studies in mathematics instead of CS. A few very helpful professors showed me how even advanced tools from mathematics can be used to study algorithms and the theory of computing, so I started a graduate degree in theoretical computing science instead. I am also one of the coaches for our ACM
ICPC team at the U of Alberta and I’m proud to say that we have qualified for the World Finals once again!
The other major part of my life is my family. I have been married to Jenne for almost 7 years now and we now have two boys named Gabriel (3 years) and Lucas (6 months).
How/When did you start programming?
I learned BASIC at school when I was 15 years old. My school was small and we didn’t have any teachers who knew how to instruct the course, so I had to take it by correspondence under the supervision of a teacher at a distant school. For the most part, this consisted of me reading through his course notes and occasionally meeting via ICQ.
What do you do when you’re not programming?
If I’m at home, I’m either playing board/card games with my wife, playing with my boys, watching a movie or playing video games. I’ve also been known to read about interesting topics in algebra, topology, and number theory that I don’t encounter often in my everyday research. Our favourite family vacation is to go tenting on a warm and sunny weekend and I also like playing volleyball and badminton when I get the chance.
What do you like most about CodeChef?
The ability to set problems that can’t appear in the normal ACM-style competition. I enjoy creating very hard problems that are still feasible in the CodeChef setting, but require a fair amount of thinking and maybe even some research to solve. I also like the tie breaking problems as they give me a chance to present optimization problems I’ve encountered in research literature in a more concrete setting.
How many hours a day do you program?
Apart from CodeChef, probably less than one hour since most of my research is theoretical. This definitely increases when I’m preparing problems for a contest.
If you could eat dinner with any famous person (past or present), who would it be and what dish would you have?
I would eat sushi with Paul Erdos.
What is the secret to being a good programmer?
Practice is the key, but you have to know where to look. Try hard problems and don’t be afraid to spend a lot of time learning new algorithms. Always be on the lookout to learn new things. Also, random bits can be your friends
What are your plans for the future?
I hope to graduate either this year or next. Ultimately, I am looking to settle at a university as a professor with both research and teaching responsibilities. Hopefully this also includes involvement in a programming contest club too! However, I expect that I will be a postdoctoral researcher for a while after I graduate since there aren’t many openings these days.
On Sunday, 20th February we witnessed an awesome contest organized by the students of NIT Trichy as part of their festival Pragyan. Bytecode was held on Codechef in partnership with Directi’s Go for Gold Initiative.
The 478 teams that registered for the contest were given 11 problems solve within a span of 6 hours!
With over 1304 submissions that we received, here are our top performing teams:
Top 10 Indian Teams:
04) Simplex Ants
Top 3 Global Teams:
01) Egor Kulikov
Top 3 Teams from NITT
We at CodeChef would like to congratulate all the winners of the contest and also thank everyone that participated.
We are also happy to let you, that all the participants that registered on the Pragyan website will be receiving certificates of merit/participation.
For all those that would like to solve the problems of the contest we have now transferred them to the practice section as well.
Congratulations once again!
