‘Fab’ruary

Posted by rudreshwar on February 1st, 2013 Filed in Announcement, Prizes View Comments

We are amongst those few who come up with a million ideas on a single day. We do not know what causes this, but it has worked for us nicely. On an otherwise mundane day of January, we got this fabulous idea of putting ‘fab’ (as in fabulous), for February making it ‘Fab’ruary. And we were serious. However, how shall we be doing it, none of us thought! But, thanks to you guys, our ever growing and responsible community and also the ever-reliable Mr Anton, as a result of the prolonged online discussion we reached at some concord.

Taking all the points into consideration, once again we were in the conference hall hitting each other with ideas (we love to call it brainstorming), discussing ways of accomplishing it. And after a thoroughly intense session ***wink*** we came to some unanimous outcomes, that aptly fulfilled our objective of our having a ‘fab’ruary. What are those outcomes you say? Read on…

Firstly, we decided to start our long Challenges on the first Friday of every month. You will have to wait till April to notice this change. Yippy. Now, you will say “Why on first Friday?” It is because, starting the challenge on the first Friday of every month gives most contestants two weekends of participation. This, we think is fabulous for everyone and the problem setters as well as for us. :) Isn’t it?

Secondly, we have decided on introducing some more goodies for the participants. This must catch your attention! But wait, the kitty is not completely out of the bag yet. In order to get your hands around these goodies you will have to make yourself eligible for them. Now you must be thinking, “How do I do that?”. It is simple. It has always been simple. Starting February Long Challenge, 3 Indian and 3 non-Indian participants, having the highest score for the “Challenge” problem will be eligible to receive these additional goodies. These 6 participants will be those who are outside the top 10 non-Indian and top 20 Indian participants of the long Challenge. More reasons to give the fabulous challenge problem its due. :) Don’t you think so?

Now, let’s lift curtains from the final fabulous surprise. From February onwards, top 5 Indian participants in every CookOff will also receive goodies, in addition to the global top 10. This means, from now onwards, Indian masterminds will also get a prize from every CookOff, in addition to immense accolades and bragging rights. So, brush up your CookOff skills and get ready to make an impact on the smaller format of the contest as well.

Combine all the aforementioned beginnings and the month of February marks the beginning of many things fabulous. So, do not wait. There is a lot more to be won. Put on your coding hats and get ready for the imminent contests.

If, you have anything to say about our new beginnings, you can always send them our ways at feedback@codechef.com or drop us a line below

Till next time, adios everybody.

See you at the contests.

Thanks,
Rudreshwar

New Prize Structure for Monthly Contests

Posted by basil on September 1st, 2010 Filed in Announcement, Prizes View Comments

Hi Guys,

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!

Cheers,
Team CodeChef

Recap of the CodeChef Campus SnackDown

Posted by basil on January 11th, 2010 Filed in Campus Chapters, Contests, Events, Prizes, Winners View Comments

On January 10th 2010, we at CodeChef witnessed the most awesome teams from campuses all over India battle it out in person at the Mumbai headquarters of Directi. 639 teams of three each, had registered for the CodeChef Campus SnackDown, a two round ACM ICPC styled coding contest. The first round of the SnackDown took place on 21st November 2009. We then flew the top 7 teams from various corners of India to prove their mettle.

The 21 finalists met on 9th January for a pre-event dinner on the night before the contest finals. Here they got a chance to interact with each other, meet Bhavin (CEO of Directi) and mingle with other personnel from Directi.

CodeChef SnackDown Finals05

Good food, interesting conversations and some fun laughs turned the dinner into a fun filled night!

CodeChef SnackDown Finals13 CodeChef SnackDown Finals11

The next morning at 9:30 AM teams met at the DirectiPlex with more food, some table tennis and of course, a 4 hour final on site round of the SnackDown to look forward to!

CodeChef SnackDown Finals29 snackdown 001
CodeChef SnackDown Finals20 CodeChef SnackDown Finals16

And now finally, after multiple rounds, tiresome travel and sleepless nights, we present to you the CodeChef Campus SnackDown Winners!

1st Place: Dream – IIIT Hyderabad

CodeChef SnackDown Finals43

Bhavin and Amit with Yash Kumar (18yrs), Nadeem Moidu (20yrs), and Kunal Jain (19yrs)

Dream is an example of national integration; hailing from Rajasthan, Kerala and Chhattisgarh, these three young programmers met at IIIT Hyderabad. Inspired by their Seniors – The Kings Gambit, they formed their own team – Dream and went on to win the SnackDown!

2nd place: Phoenix – DJ Sanghvi, Mumbai

CodeChef SnackDown Finals42

Ramki and Bhavin with Purav Shah (20yrs), Pratik Tandel (20yrs), Krunal Manik (20yrs)

This team’s friendship goes back to school days. Having started programming in the first year of engineering, they were introduced to algorithms and contests by their friend and mentor Varun Jalan (most of you know him as syco). Under Varun’s guidance team Phoenix was formed and they are soon going to represent India at the ACM ICPC world finals in China.

3rd place: CounterGambit – NIT, Trichy

CodeChef SnackDown Finals40

Bhavin and Yazhini with Akhil Ravidas (20yrs), Abhilash R (20yrs) and Venkatesh Basker (19yrs)

Counter Gambit is formed of three hardcore Southies. Since each of them are from completely different programming backgrounds they have their our own strengths and weaknesses. However, as a team, they are really quick in solving problems which helps them  get a head start in most contests, or so they’d like to think ;) They too are representing India at the ACM ICPC world finals this year.

The rest of our finalists are (in order of ranking):

Team: TheKingsGambit
Institution: IIIT – Hyderabad
Team Members: Anshuman Singh (21yrs), Gaurav Agarwal (22yrs) and Rajat Goel (21yrs)

Team: BruteForce
Institution: IIITM – GwaliorTeam Members: Shilp Gupta (22yrs) Manyata Goyal (21yrs) and Vineet Chaudhary(22yrs)

Team: CKrackers
Institution: Madras Institute of Technology
Team Members: Rajesh Venkatachalam (20yrs) Rajesh Rajagopalan (20yrs) Gokulakrishnan Gopalakrishnan (20yrs)

Team: DareToCode
Institution: IIIT – Allahabad
Team Members: Imran Khan (22yrs) Surendra Kumar Meena (21yrs) and Tasnim Khan (20yrs)

CodeChef SnackDown Finals48

We had a lot of fun with the CodeChef Campus SnackDown and would love to do something like this again. We also have some fun interviews with the rest of these teams so let us know if you want more insiders information. :)

Cheers,
Team CodeChef

Feedback:

We removed the submission limit on the challenge problem this time as the problems were considerably tough compared to the ones in the previous contests. We agree that some of the problems had a very strict time limit and this issue will be addressed in the future contests.

Also, if you have any kind of feedback related to the contest or otherwise, feel free to comment.

Regards,
Aniruddha.
