It was during SnackDown 2016 that we witnessed the finest programmers from across the globe competing on a single stage for the first time in India. We thoroughly enjoyed watching top school programmers take on the top university and professional programmers. There are many such moments during the previous editions that we cherish. And with all the fond memories in our kitty, we are super excited and eagerly looking forward to the 4th edition of SnackDown. The preparations are up, we began with the first steps for scouting and finalising the best possible dates for the competition. We did a couple of surveys within the community and we present the results below.
A sneak peak through the survey results.
The first survey was taken up by 654 players. Of those, 76.1% were available for the proposed day of online qualifying round (5th May to 7th may) while the rest voted out with primary reasons being end semester exams and summer internship.
Despite a majority percentage of players being available, we had to opt out of the proposed dates since quite a few people could not attend the qualifying round. Thereafter, we have brainstormed further about the dates and rolled out another survey with the new dates and an additional day for the online qualifier.
The second survey received responses from over 1200 players which was very heartening. Of those, 80.1% voted yes for the new dates (20th to 23rd May) while the rest did not. The percentage and participation was higher this time and hence we decided to go ahead with these dates. While this clashes with the ACM ICPC World final dates, we believe that it will be good fun for the finalist teams to take out a few hours to crack the qualifier.
After analyzing both the surveys we have finalized the schedule – Please go through it here:
Now it is time for you to gear up, form a team and prepare for the ultimate battle of brains.
Oh wait! We are yet to discuss the team formation rule that we had in our previous editions. If you are hearing this for the first time or forgot what it was, then you should head over to the following links here and here. Though our intent was to bring a matter of pride for the players to represent their institution/organization at an international level, we realized that there was very little acceptance from the community and that restriction wasn’t well received. After considering all the concerns raised by the community we decided that there would be “no restriction on team formation” in this edition. And finally, here we are presenting to you the CodeChef SnackDown 2017 in a truly open and a global avatar!
Keeping watching the space for more details and surprises about SnackDown 2017!
This is in a series of gifts that we are bringing in to give you as a part of our Birthday treat. After the new goodies, we are super excited to give you a brand new system to calculate the ratings on CodeChef, along with the new rating bands! We are also introducing the combined CodeChef Rating, which takes into account all the rated contests on our platform. Which also implies that we are bringing in more Rated Contests! Read on.
It was more than a year ago, that our then intern and now chef, Vishal Sharma teamed up with our beloved user and intern Surya Kiran to formulate the math behind the system. We took up the task of revamping the rating system because with time the present one started developing issues. Inflation of ratings was a major concern and this resulted in a wide difference in the ratings of users specially at the top, e.g., between rank 1 player and the rank 2 player. Fixing a rating band to reflect the skill of a player was also something that we wanted to incorporate.
The new rating system is a modification of the ELO, tailored for group contests. A very basic idea of how the ELO system works is this: Whenever you participate in a contest, you compete in a duel with all other participating users. Based on your existing rating and the other participating users’ rating, your probability of winning against each of them is calculated. Your actual performance is compared against this expected performance, and correspondingly, you gain or lose some points. The nitty-gritties of the system for the more mathematically inclined can be viewed here.
Some salient features of our new system are mentioned below:
The new combined CodeChef Rating: A major shift in our new rating system is the introduction of the combined CodeChef Rating, so as to have one single rating for the entire platform. This is in addition to the ratings calculated independently for the Long Challenge, the Cook-Off and the LunchTime contests. This combined rating is arrived at, by using the same algorithm for each contest that the user has participated in, in chronological order of participation without discriminating based on contest type. It is important to note that it is not computed by summing up the independently calculated ratings of the Long Challenge, the Cook-Off and the LunchTime contests. Doing this has the advantage that missing out on any one type of contests won’t affect your combined CodeChef Rating. You just end up losing the opportunity to increase your rating in the contests that you miss.
The new rating bands – Time and again, we kept receiving feedback for introducing rating bands. We took this opportunity to introduce this most wanted and a long awaited feature. We brainstormed on how best to represent this, and we zeroed in on two main, but opposing, factors: The coders should be comfortable with the representation, and this meant having colours as in most other platforms; and the other factor being accessibility to outsiders. We would love to see the sport of competitive programming gain traction, not just among participants, but also as a sport suitable for public following. We wanted outsiders to immediately understand how good a person was, and having only colours wouldn’t achieve that. We settled on introducing Stars, as they are universally recognized representations of skill. It also opens the doors for you to brag about your stars.
We present to you our various rating bands and their corresponding stars and colours:
<= 1399 : 1 Star 1 ★ 1400 - 1599 : 2 Stars 2 ★ 1600 - 1799 : 3 Stars 3 ★ 1800 - 1999 : 4 Stars 4 ★ 2000 - 2199 : 5 Stars 5 ★ 2200 - 2499 : 6 Stars 6 ★ >= 2500 : 7 Stars 7 ★
External Rated Contests: Currently, we have numerous contests organized by various colleges and organizations, and hosted on CodeChef. We will curate these contests, and the contests which we find to be good enough will count towards the CodeChef Rating. So, if you are conducting a programming contest for your college fest, this gives you an incentive to make it even better. You get the chance to get the best coders of the world to participate in your contest, as there will be CodeChef Rating points up for grabs! Get in touch with us if you want your contest to be rated.
A new combined Junior CodeChef Rating: For students of middle and high school, we have introduced a new combined Junior Rating system which will calculate the rating of all rated contests considering only the middle and high school students.
A brand new User Profile: We have revamped the existing user profile page to show your performance with swanky new graphs. Play around and we are sure you will love spending hours on it.
Important links: Head over to these pages to get an idea about the new ratings and rankings -
The distribution graph for the new CodeChef Ratings:
* Above is the current state of rating distribution as of 9th March 2017. Visit your profile to check your ratings.
The old ratings: We will keep the old ratings at the below given new URLs to refer your performance in the old system, in case you may have used that anywhere.
Penalties on Plagiarism: Users found cheating will be penalized heavily. The first time they are caught, their ratings will fall by 500 points. The second time, it will fall by 1000, and they will be banned on the third instance. This will be done from now on.
We are so very excited to bring this to you. We have worked very hard to do so. Since the change is big and spread over the entire website, there may be mistakes. We would like you tell us any issues that you find and do send us your feedback.

Birthdays are about sweets, cake, balloons, and lots of fun with your friends. Add presents to that list and suddenly the whole day gets brighter. Make them gifts a surprise and it’s tough to contain the excitement. So, we thought we would include all of that in our month long birthday celebration, for our 8th anniversary.
We started with a cool and calm celebration by devouring cake and pizza with our ever-hungry team members. But as stated, that was just a start. We have planned a whole lot more for you and us all. Some cool new developments on the website, some new developments for you, some new prizes, some new categories, and some surprises which will unveil themselves when the time is right. So, should we get the celebration started? We think we should.
When we say “nothing excites us more than new stuff,” we think we speak for us all. We thought we will introduce some “new goodies” to our collection and offer you an even wider range to redeem your laddus.
So, what are these new goodies that we speak of, you ask? Well, let us list them down for ya.
Head over to https://goodies.codechef.com/ and check out the latest additions to our goodies list in detail.
New Prize Categories:
It’s another “new” for you all. In our attempt to encourage programming talent from a wider pool, we have introduced some new prize categories on top of our existing ones. So now, we will see a lot of new programmers getting their hands on CodeChef goodies for the first time, some even multiple times. Now, let us introduce you to the new categories.
Random Laddus: Every rated contest, 5 participants will be randomly selected, and they will get 200 Laddus.
100% attendance participation reward: If a user participates (ie. solves at least 1 problem; and even partial solutions are counted) in each of CodeChef’s monthly contests (Long Challenge, CookOff, Lunchtime) in any 12 month period, then they will get 1000 Laddus. That is, if at any point, a user has participated in the last 36 CodeChef Monthly contests (ie. all the three contests in each of the last 12 months), then they will get 1000 Laddus.
Contests before March 2017 will not be counted. Once the prize has been claimed, the counter will be reset.
So mark your calendars!
First one to solve each of the problems individually: In each rated contest, the first person to solve each problem (100%) will get 100 Laddus.
Tiebreaker problems are excluded.
If there are at least 100 (and < 200) participants from a particular country (excluding India), then the top 20 from that country will get 40 Laddus.
If there are at least 200 participants from a particular country (excluding India), then the top 30 from that country will get 50 Laddus.
If there are at least 20 (and < 30 ) participants from a particular country (excluding India) who finish in the top 300 in the Global Ranklist, then the top 10 from that country will get 250 Laddus.
If there are at least 30 participants from a particular country (excluding India) who finish in the top 300 in the Global Ranklist, then the top 10 from that country will get 300 Laddus.
So go get all of your friends to participate and enjoy the rewards together!
Note: A user can get Laddus from at most one of the above two events.
The streak will be reset once the prize is claimed.
Note: Users who have been caught cheating will lose 50% of their Laddus, or 500 Laddus, whichever is higher.
So, is that it for the celebration?
Well, not exactly. We have just started. We have a huge star-studded colorful present waiting for you just around the corner. So, keep watching this space and be the first one to get your hands on your presents as and when they are unwrapped.
With that, we will put our party hat back on and head over to where the celebration is: our contests. You too join us there and have fun.

Today is the day when it all began – the day when the cerebration of creating a truly global programming platform, while amending the programming scenario in India, transitioned from our minds to the canvas. And CodeChef was born.
Seven years, thirteen hundred contests, and over nine million submissions later, here we are with you all by our side, standing tall as ever. It has been one joyful ride to say the least. The transition from infancy towards adolescence has taught us some hard lessons and given us a plethora of moments to cheer. And to give credit where it is due, let us start by thanking those who made this happen.
First and foremost, it is you, who constitute the heart and soul of our community. None of this would have been possible without you. You have been there with us through the thick and thin of it. Always.
The conscientious SPOJ team for its constant support through their unwavering and loyal Judge. You’re the engines powering our McLaren.
Our amazing Chefs – the problem setters, editorialists, testers, the translators, and the omnipresent contest admin. They define what we are.
The support team and staff at Directi, for ensuring that CodeChef is up and running 24×7. They are the people whom no one sees or knows but they keep working behind the scenes to help us run the platform.
All our beloved team members, interns, former and current, who worked hard and are consistently working (when not on the foosball table) to take CodeChef to newer heights.
Every single individual above has contributed immensely towards the development of the CodeChef platform and community.
Now that we have thanked all the people involved to take us where we stand today, it is only imperative for us to show you our report card. The effort put in by everyone associated with CodeChef certainly isn’t quantifiable. If anything, it’s an indication of how far we have come from where we were when we started. And it does make us happy today. We hope you like them too.
* All the data mentioned above is from March 2011 – February 2016
If there’s one word to describe our past year, it would be turbulent. We saw some amazing highs and we have been through some crushing lows. And as we embark upon another year, let us take you through some of the highlights of the year gone by. Do share your favorite moment of this year with us.
To start with what pegged us down, it has traditionally been the shorter format of the game. We have been found wanting in handling the load at the start. And this year too has not gone without those hiccups. The load is an indication of your growing love and we were extremely disappointed in not being able to do justice to it on multiple occasions be it the August Cook-Off, Amritapuri Online Round, or the Hindustan University Online Round. We have made plenty of improvements to give you a much better experience at these short contests, and only when we thought that things have improved we were fooled once again in our last CookOff. Are we doing anything about it? Certainly we are. Do read about it here.
With the goof-ups behind us, let the happy times roll in and let us brag about some good things too. What may seem to be contrary to popular belief, most of our engineering team’s time this year went into performance improvements. We hope you will see and experience the benefits soon. However, there are also some other moments/feats/features that we have achieved in past one year, that bring smiles to us.
We brought back our annual onsite event SnackDown after a hiatus of 5 years. With participation of over 8K teams from across the globe in the SnackDown 2015, this was clearly our biggest event of last few years! We only hope that this continues to be a more regular annual event from now on.
For our little friends in schools, we introduced the beginner category in our practice section.
We added a tad more security to our kitchen as we moved to “https://” from “http://”.
Coming to the performance fixes, we changed our caching layer and contest page loading logic.
To add a pinch of excitement to our contests, we introduced the feature to freeze rank list, hide time and memory of submissions in a running contest.
Our online IDE “CODE, COMPILE & RUN” became more flexible with the introduction of multiple tabs and code saving features. What was even more exciting was to make submissions to problems through it!
Our comment page got a facelift, becoming even more interactive and secure.
We feel great about the fact that we could be of help in hosting the ACM ICPC Amritapuri Regionals onsite round, when things went bad. It was a moment of huge test for us to be able to make sure that nothing gets goofed up in transitioning a running contest, something that we had never done before. We are happy that we were able to do it as we have been ourselves been a victim of load failures many times in the past. This undoubtedly tops our list of feats we are/was/were/will be proud of.
We ended up hosting all the rounds (including online and onsite) of all there ACM ICPC 2015 – 2016 India regionals. This was the first time we hosted an onsite round for any ICPC regionals.
And finally, the effort that we have been putting in with CodeChef for Schools. Now into its second year, the initiative has seen a slow start but it has started finding firm steps amidst the programming fraternity. We have seen a constantly increasing presence of school students not only in our monthly contests but also across all other programming contests/workshops in the country, which is an indication of brighter things to come in the future. We also have many schools, colleges, students, professors and professionals from around the country joining hands with us in promoting programming among the schools.
Most of these features and changes, which we introduced in the past year, were all result of your feedback and suggestions from our community members and we will continue to follow the process. Keep sending your requests and choke our pipelines – it keeps us busy and helps us make the platform more suited to your needs.
And now, it is gifting time. Yes, what is a birthday without some giveaways? So, here a small gift that we hope you will like. There is a lot more exciting stuff that has been keeping our Chefs up till late nights and you can expect them soon. Very soon.
There is a new “Laddu Accrual System”. Yes, it’s as sweet as it sounds. We are sure this will bring a lot of smiles to the community. We are aslo running a small contest on our facebook stream. The first one to find out the correct URL for our newly launched Laddu Accrual System, gets 300 laddus. So, what are you waiting for? Let the website scrapping begin?
Now, while we take a dip in the pool of accolades accumulated in the past one year and use the critiques towards enhancing the platform, you go search your closets for your party hats and bugles. Because no matter how clichéd it sounds, there can never be a party without you.
That will be all from us for our 7th anniversary blog. It has been quite a ride with you all, and we hope to have many many more. With that it’s time now to start the celebrations of our 7th anniversary and we hope to find you all by our side.
In anticipation of yet another exciting year ahead, let’s set the ball rolling.

The floods in Chennai that engulfed the city have passed and the city is coming out from its state of disarray and wreckage. Our empathies are with all those it affected. The spirit of the individuals and organizations that helped out during Chennai’s time of need was truly inspiring.
As everything came to a halt, the ICPC regionals were naturally rescheduled. In the aftermath of the floods, the Chennai ICPC Regionals will now be held on the 23rd of January and undoubtedly, enormous efforts were put in to resurrect this contest. Team CodeChef will visit the regional site to support the teams, help out with registrations, and most importantly see the contest go superbly for everyone.
The CodeChef kitchen is already emptying once again as we leave for the Regionals in anticipation of a great contest and a rejuvenated Chennai.
We hope that with all the combined efforts going into the contest, the teams will have a good environment to code in, and will make this chance to go to the World Finals really count. That being said, our heartiest congratulations to all the teams for making it to the onsite contest. And all the very best for #ICPC2016 regionals.
That’s all from Team CodeChef for now, we will be in with more news from #ICPC2016 soon. Till then, keep coding!
It is morning and people are on their way to work, nursing their Monday blues. While the repetitive nature of the work-week waits to unfold for many, things are not quite the same for the students gathered at the ACM ICPC 2015 Amritapuri Regionals sites. The air is singing with enthusiasm and anxiety all at the same time. The participants have entered the contest arena and the next few hours will decide who goes to the ACM ICPC 2015-2016 finals at Songkla University Phuket, Thailand.

doped_ducks in a tangle of balloons:
2:13pm: The rank table has bitbees, angle, Nullstellensatz, doped_ducks leading with maximum scores in this order. Changing rank tables have us waiting on the sidelines, but we will keep you posted on the happenings at the ICPC Regionals. Hold your breath
2:45 pm: Coins, Coprimes and Magical Matrix seem to have stumped most teams. let’s wait to see who gets them first!
While the ranklist decides who is beating whom, lets sidestep and go see the jury room!
The Rank list can only tell you so much Last few minutes of the contest and nobody knows what will happen. Cross your fingers and wait a while.
It is that time of the year again – when we at CodeChef pack up our backpacks and travel to the sites of the ACM ICPC regionals. Needless to say, we are stoked! Our office has become a makeshift inventory shed with all the cool goodies taking up a lot, and we can’t stress on the word LOT enough, of space! For weeks we have been prepping for this yearly encounter with all those brainiacs at the ICPC Regionals and we are all set to go see them.
We will be there interacting with the participants during registration where we will definitely see everyone putting their poser face on for #myicpcselfie and will catch up with them later during the practice round too.
It has been a chaotic week back at the kitchen, with all the goodies being designed and redesigned till they are absolutely perfect! We hope you like them as much as we do.
Also, a shout out to all those who have qualified for the #icpc2015 regionals, congratulations and all the very best! We are hoping for some exciting contests among the teams, an amazing event, and lots of fun getting to know all the enthusiastic coders. That’s all for now, we have flights to catch!
PS: To all candidates eligible for the travel reimbursement, come with your documents, find one of our team members ( you will find us at the registration desk on Day 1) and hand them over to us.
