Snackdowners,
We understand that there were some problems with the contest this weekend. For those who missed it:
- Despite a few days of frantic optimizing, we still experienced some issues in the first half hour of the contest due to heavy load on the server (about 300 teams registered in the last 3 days – doubling our expected amount). There were multiple complaints of people not being able to access the site at the contest’s kickoff.
- The test data and the sample input/output was wrong for the problem SUM12. Some of you figured out our mistake and were able to still get the solution accepted… well done. For others, this seemingly easy problem led to a lot of frustration.
We’ve evaluated all the options and here’s what we are going to do (brace yourself)… Re-Snackdown: Sunday December 20th 4-7pm – only teams who solved at least 1 problem in the original Snackdown are eligible for the finals/prize money. Some of you are screaming at your monitors (especially those in the current top 5)…this isn’t fair… we hear you but there is no way to make everyone happy. We screwed up, we’re sorry. Here’s the other options and an explanation of why we are taking this approach:
- Do nothing – Everyone had access to the same set of questions, good or bad, 7 teams were able to solve three problems. Invite them all to the finals. We almost did this, the reason why this doesn’t work is mainly the placement of people from 7-20. A lot of people solved 2 problems, and since we are giving out money, it depends how long you spent on and how many wrong answers you submitted for SUM12. Didn’t seem fair to distribute money based on this.
- Rejudge SUM12 with the correct test data and eliminate penalties for this problem – While this approach seems logical at first, it doesn’t help the people who spent a lot of time on this problem. We’re still stuck with the same issue as above (doing nothing) except add to that the complication of multiple people now having solved three problems. We think a lot of people will end up not liking the results.
- Re-Snackdown – We considered leaving it open to anyone, or allowing anyone who solved a problem or attempted SUM12 to participate. We are limiting it to those who solved one problem and treating this like an elimination round. This may seem unfair to those who spent all their time attempting SUM12 (without solving any other problems correctly). We believe that there were enough comments to indicate there was an issue with the problem and at least one other relatively easy problem that could have been solved in the time limit. By limiting the participants, we are also decreasing the load on the server for the next round (though we are working on fixing this). The next contest is on a Sunday afternoon post exams (Dec 20th), and last 3 hours (4-7pm).
Some people will undoubtably feel like we should’ve taken one of the approaches listed above (especially those in the original top 5). We’re sorry, don’t hate us… feel free to comment and let us know what you think… try to be nice.

Here is why SnackDown should not be rescheduled -1. Because we were in Top 5.. :)2. Our Holidays will be going on and I DON'T WANT TO RUIN IT.3. My team mates will not be together. How can you expect us to participate in a team contest without having team members around, and perform well.Everyone had the similar problem. All the Participants were equal. Nothing was biased in the contest. The rank list that was there was the final one, where everyone was equal whatever be the case.And about not hating you, after your decision you make me hate you more….

Second option should have been implemented bcoz we feel teams are experienced enough to move on next problem if they are getting continuous wrong answer on the same problem.I dont think teams had spent all time trying to debug this problem alone.

I agree. Many regionals also have wrong problems and their result is never changed. What makes this worse is the fact that there were only 5 problems with 2 of them proving to be very hard and almost unsolvable.I think ideally there should've been atleast 7-8 problems for 5 hours. Please do your research well. And what happened with SUM12 was really shameful. What are the admins doing and what are they paid for to let such an error go through and being inactive about it throughout the contest?

Yes.. most of the colleges have winter break whole december.. and its not possible for all team members to get together in middle of it, just for the contest.

How I find the current situation :1. You conduct the contest on Dec 21.2. There were some server problems and the test data and sample input for 1 question, SUM12 were wrong. 3. Some teams spent all their time on SUM12, while some others concentrated on the others. Some were lucky to find out the mistake in the judge.4. You give FULL advantage to those who spent all their time on SUM12 and COMPLETELY neglect the ones who did the others. There is no decision that is completely fair. But you can atleast give some advantage to the ones who solved 3 questions, rather than simply making this an elimination round.

Sorry, I meant Nov 21st.

Hmm.. this seems to be fair enough now. The main objective of these contests is, ” Test Algo + Programming skills by giving unambiguous problems “, and nothing else.. like.. move to other problems (unless they broadcast everyone the same to everyone in beginning of contest), do some guess, get lucky.. etc., The objective is not fulfilled.. so there is no unfairness in having a re-match. ..and using this one as elimination seems fair in many ways. Thank you !

plzz move the contest to january atleast …we will be having our exam on dec 20..Better put a poll about the 3 options..and lets see what majority is looking for

It is fair enough…although the snackdown is in dec. now , but it is good to see a decision that Fair to all i think .The opposing things>>>1)the first reason is exams but many institute having end-sem currently running.so it is a general problem Nov and dec are like so .2) The second is winter break so for a Good contest we can arrange ourselves so that we can compete in.. But both are general things there will be always some reason like this.in jan placement season.so it is the best.
ok u are one of people who continuously try same problem even getting wrong answers whether other problems are easy or not.

I agree with kunaljain and idivyanshu And also I am from bits goa and i am eligible for the prize money but my end semester exams end on 23th Dec .. Now what do i do ?? According to me either option 1 or 2 would make more sense !!!

Better option will be as some one said
1) Select top 7 teams for final
2)give equal prize to all those teams who solved 2 problems
It is really unfair to give undue advantage to those teams who salved only one problem and didn't have any idea about the 2nd problem

Scheduling a rematch seems the best option. It is also true that contestants will be having their holidays in december and the team members might not be able to meet up for the event. What I prefer is doing a kind of poll as to what the eligible teams prefer : A match in December or in January ?For CodeChef Guys : Mistakes can happen by anyone π . Seeing that you guys made a mistake unintentionally, we(at least I) wouldn't hate you for it. I already appreciate a lot that you guys are doing :-). Helping the country make better programmers, providing tutorials, practice problems, and videos, and giving out huge prizes every month and yet ask for nothing in return is way much more than to accomplish for a small mistake :-).

Hmmm … I would say this is a better alternative:Take the teams which are in current top 5 (union) teams who will be in top 5 if problem SUM12 was cancelled. There will probably only be 7 teams in this manner of allocation, of which 1 team (phoenix) will not require flight tickets. So, you will need to pay flight fare for only 1 team extra. The onsite contest can be played with the same prize structure for the top 7 teams as it is currently and hence, i guess it will not be a big loss. Even this alternative has minor flaws but i am sure they are far lesser than the flaws in the current idea implemented.And of course, errors happen almost everywhere, and it is not a big thing to feel about :)Best RegardsVenkatesh (CounterGambit)

I agree, there was no solution to this problem which would have pleased everyone. Regarding the problem that it is unfair to the top five teams, then probably had there not been an issue with the SUM12 problem, other teams who got a lot of penalties on that problem could have made to the top five. So what you have decided looks quite fair.And these issues happen with ALL famous programming competitions, so the question of hating you does not arise. π

” other teams who got a lot of penalties on that problem could have made to the top five “There are only two more teams that could have made a place in top 5 if the penalties were removed, otherwise there were no teams that could have done..as you don't need around 3hours to solve a problem…:PI agree with Venkatesh that the top 7 teams should be called to the Finals…

I second Venkatesh's proposal, which puts no(or may be 1 or 2) teams at disadvantage. I see the present proposal as completely ignoring the efforts of those in top 5. I hope codechef takes into account about this, before deciding anything.

I don't see how giving away equal prizes to all teams that solved two questions seems fair to you. Probably your team solved two questions and hasn't really got a nice rank. Could you please tell me your team handle even if your team hasn't got a bad rank or what I mentioned was not your contention.

In real world, you can never measure absolute skills :). Any contest even if it has unambiguous problem statements etc, can always give unfair advantage to some contestants just because they have seen a similar problem before.So the purpose of programming contest is, to find out how contestants fair on a particular day in a particular problemset and conditions. Its unfair when some teams are provided with favourable condition and others are not, which is definitely not the case here. Everyone has the same condition you know ;).I dont like the idea of a re-contest, but then again its codechef's decition.

I'll support your thinking only if you can prove that the amount of time wasted on SUM12 for each team that could solve it but after getting moderate penalties and solved exactly two questions, added to the time required for them to think about the third one could not have helped them get it accepted under the time constraints of the programming contest.

How could you say that “1 or 2 teams would be at a disadvantage” ? Probably the teams that wasted their time on finding the faults in the problem SUM12 and yet be able to solve it after getting penalties and still having got only two accepted in total, could have solved the third one had there been no ambiguity in the problem statement.

@ajaysomaniIn a contest few teams solves a question and then problem statement is changed suddenly while judge data doesn't changes making the sample I/O test case completely different from what judge I/O is.Some teams take their luck , submits solution based on first sample test case which they have seen and got AC. while those who are absolutely sure that they has correct solution and passes given sample I/O ,continuosly get WA.how can you call this a fair(if i get correctly this is what you are saying) and equal contest for everyone.It will be like judges are simply ignoring there responsibility in organizing a contest.If it happens in future again then they will not care about it and call it a fair contest again.had problem with sum12 not happened ranking will surely be completely different.Now for those who opts for taking first 7 rankers in final. I agree with you but one simple question how will you line up the ranking of team 8…20. Ofcourse they have also participated in the contest whole-heartedly for 5 hours so you simply cannot divide equal amount of money among them and run away from your responsibilites.These ranking are equally important as first 7 spots.So ,if you think of cancelling out problem SUM12 and then arrange these rank , then why not let it be done for entire teams participating in snackdown and take the first five spot to final instead of seven.Surely except re-match, for every decision you take it will be unfair to some team and you simply cannot ignore it because it was fault of organizer not that team.

How much time do you think one needs to code if he has already figured out that the the solution to SUM12 was to jst find out the Fibonacci Numbers in O(log N) ?Around 1 hrs will be ok for any person who even has no idea how to calculate Fibonacci Numbers in O(log N). Even it did not accept atleast the team had the code ready..While for the question Rational Numbers The maximum time took for any team that solved atleast two problems was 02:57:23. While the average was 1 hr 10 mins..So I think that gives enuf time for someone to solve the Matrix Games Problem..I think you u got the explanation π

@somani: “which is definitely not the case here…” , I think it is the case here. As teams submitted initially based on sample cases given ( though they might have known it is wrong logic .. ) , and sample cases have been changed just some time after the contest began.

Just think about this, There is a problem in the contest, uses some theorem X, a team sees the question, realizes that theorem X is to be used, lets just solve. Some other team keeps trying, they dont know about theorem X. Ultimately they dont win the contest. Would you consider this fair?By fair and equal contest, I mean everyone had identical conditions. Its not that some team saw different sample input output than another team. They all saw the same input output. Some realized its wrong and they went through with their submission. Some didnt.

IMHO this only effects time penalty and not the fact that some teams solved the problem and others didn't. So the idea of calling the top 7 teams to the finals is better according to me.Its of course unfortunate that some mistake happened, but Re-contest is not the solution.

“Its not that some team saw different sample input output than another team. They all saw the same input output. Some realized its wrong and they went through with their submission. Some didnt”Problem is that sample input output is not wrong but master input output

I don't understand how people can simply forget that there was a question named “matrix game” and take decisions solely on the basis of the question “SUM12”. Does this mean that all those who did the matrix game were doing something useless? Why don't you give any credit at all for that question?? And what about the time taken to do the question rational numbers? I don't blame codechef for making a mistake. No one is perfect and these kind of problems are normal for programming contests.

So many teams..so many opinions π
However every body have a valid point
I hope the admins create a opinion poll here where top 20 teams can participate to choose the most preferred options
All the top 20 teams worked real hard Saturday ..so all of their opinions should be valued before taking final decision

The problem is with ranking of top 20 team and almost every team knew that theoram X. Infact team at 21 ,22 and 23 knew that theoram X too.So, has these teams made some mistake in not realizing that judge data is wrong and they must submit solution based on first sample input / output which they had seen which was again logically wrong too.Do you expect them to submit solution which they obviously knew is wrong and has no reason to be AC.and even if you assume it be correct then what lesson will you want to give teams participating in Codechef. Don't believe in Codechef's judge data ,submit what you feel is correct.

Your thinking might be wrong.

My point is that “the whole point that judge input/output of SUM12 was wrong hence can't solve other problems is wrong” . Time was enough to do other problems

Perhaps the time was enough for you. You can't say that it was enough for all the teams unless each team says it out here explicitly.

Guest who ever you are, I dont think that you are an idiot to not understand the point that If a solution which you think is Correct and still getting wrong answer and you think that no other changes can be done to it…Will stick to the same problem for the next 4 hrs jst to get the damn question accepted…If you think it was wrong and you commented, maybe you'll wait for the reply to it while try some other question which you think is suitable for you to solve..I think you didn't find anything suitable to solve yourself and you wanted some position in top 20, and thats why you tried the question SUM12 for the rest 4 hrs….:P

Really I totally agree to what neel said…There are lots of opinions which are very much valid from their own standpoints….which nobody cant simply ignore…so i hope before Codechef admin decides upon something they should create a poll with all the options which have been cited and raised here…and then they should accordingly decide..As on that very day everybody had put their effort for something productive and big…Codechef admin should reconsider their involvement…programming contests of this stature is very different from any other …here people code with major expectations…So i too feel the final decision should be based on the basis of a poll that Codechef Admin should create..

Ya.. true.. decision should have favored those who did rationals and matrix game ( 7 teams (?) ), but time should not be considered in that case.

How do you think that poll will give a fair result.every team will take the decision that best suits them and you know there are many teams after first 20 spot , and for each of them re-match is the only option.

I know judges have already taken their decision…but may be there is a need for reconsideration as so many people have problems..just think about it …i have exam on 21st dec…nyway i dont want to take only my interest into account.Thats why i suggested a pole..where every one can give their preference..i believe that will be the fairest choice

And i personally feel that the poll should only be accessible to those who have solved atleast 2..because those who have done 1 are always going to want a rematch…

This is the best way of saying that the top 5 teams should not be given any preference π

There is nothing clear , once the result are obvious.Having a poll will just meant you don't aggree with current codechef decision taken.As they have already mentioned , they looked at entire point and then have come to this conclusion.It wasn't easy for them either.So, why not instead of just shouting and replying in this blog, we respect codechef decision and wish a best of luck to codechef for next contest.

And probably the best that could have been or can be done which i already mentioned at the end of SUM12…which is if Codechef keeps every submission of all the teams then they could rejudge their submissions for problem SUM12 offline and based on their first successful submission they could be ranked and keeping all other as they are now…

you all know that SRM 453 was canceled .SO on “25th” all of you giving the SRM 453.5 .don't you have problem in that.so it is the most common solution of any site. Reply to:neel8986you know india is second largest population in world.so there are many problem on each day .so if codechef want to consider everyone's problem then it will be the 367's day of yearthat is appropriate for contest.Don't take it wrong it is the matter of adjustment so just schedule your time.there can be shifting of time of contest but don't talk about Date . there as many colleges so all having

Do you know how many colleges are having their endsems right now ? Even on the day of competition, we had our exam due to which I had to give the competition alone since my team mates couldn't make it due to their exams. That wasn't fair, was it ? So, please stop being so desperate. Thanks

Thats exactly what i am saying .. why repeat the same mistake again ?? Schedule it properly … but again there might be 100 other problems which we may not expect ..Whatever decision codechef takes we should respect it !

even we had our exam on 21st and 22nd november. Actually entire team that participated from IIIT Allahabad had there end-semester exam on that particular date(that includes 3 team in top 20).Date can be fare to some team and not for others. Particularly I wouldn't mind if they change the date for re-snackdown but what if new date which they select doesn't suits me.Should I come here and complain them to change the date again.

Why is the next contest of 3 hours? Isnt ICPC traditionally meant to be a 5 hour contest?Please keep more than 5 problems and if possible invite more teams to the onsites. 5 teams to the onsite really calls for heartbreaks more than anything else. Hope teams which were qualifying this time dont have to go out because of this decision.

We wanted to create less of a time commitment for your team. We will include more then 5 problems. We will consider inviting more the 5 teams.

I think that is a good idea of not disregarding the efforts of the top five teams, as well as giving an opportunity to the others.

Almost 1 month has passed for the Snackdown and Re-Snackdown is just 2 days ahead, yet there has been no notification to the students regarding the overall decisions made mentioned in this BLOG.Students have registered for the event through their email-ids and they deserve to know about all the things mentioned here through email. Atleast provide them the blog link.

There are no changes to the decisions outlined in the blog post above. We appreciate all the feedback. We may choose to include additional invitations based on performance on the first snackdown but that decision will only be made after the resnackdown. You can assume that the top 5 teams from the resnackdown will be invited to the finals, if we choose to expand that we will make an announcement after the contest. Thank you.
