Hi all, an important announcement about icpc (https://www.amrita.edu/icpc21)

It has been decided to conduct the Asia Amritapuri ICPC Preliminary and Regional Round in the month of June and July respectively because of the current pandemic situation. Registration will end 10 days before the Preliminary Online Round.

Teams can register at two sites as per the rules, if the contest is announced by other sites. Most probably Kanpur & Gwalior sites also will host the contest. that case, there will be one single round of online contest. This will be announced soon~.

Tentative date for the Preliminary Round Online contest: Last week of June 2021.

Duration: 2.5 hours

There is no registration fee to participate in the Preliminary Online Round.

Regional Round: July second week.

Duration: 5 hours

Teams will be promoted after the Preliminary Online Round.

Regional Round will be held online on CODEDRILLS platform.

Amrita will host the regional round in the online mode with the following selection criteria.

Total Slots: 700

Teams solving at least one problem in the Preliminary Online Round are eligible for the Regional Round. Top team from each institution is selected first. Rest of the slots are filled in the rank order.

If any queries related to this or ICPC registration, please ask at CodeDrills Discuss and we will try to get it answered by Amrita staff.

UPD 1: I have collected all information that I could find about the regionals here.

UPD 2: We will be conducting a mock contest for those registered for ICPC Amritapuri (details at https://codedrills.io/contests/icpc-amritapuri-2020-mock-round ). We strongly suggest you get familiar with the platform by participating in the mock contest and ensuring that your login works. Make sure you resolve any issues faced well before the main contest. We won't be able to resolve any login related issues that are reported later.

Balajiganapathi What will be the eligibility criteria in order to participate, keeping in view the students graduating from college in this summer?

    According to rules at https://icpc.global/regionals/rules, it seems you will be eligible as it is ICPC 2020. Relevant quotes from the rules:

    Note: The 2021 World Finals will be held after the 2020 World Finals and announced as soon as the world situation allows.

    Note: If the 2020 regional year is delayed, we still determine the eligibility at the point as if the year was not delayed (normally October 1 2020).

    If you can post in discuss, we can get this confirmed by Amrita staff to be extra sure.

BTW, so this effectively means that all the 700 slots in Amritapuri are now college-reservation based, right? (if not, can someone pull the numbers as to how many unique colleges we had in past years?)

I would really appreciate it if there was atleast a single regional which had 350 ranklist-based + 350 college based — that seems fair to both. Otherwise, basically if you're from a competitive college it's probably harder to qualify from your college than to make wf (consider IIT Roorkee last year, 2 teams made wf) :(

    I think the reason all regionals go for college first is because world finals slots allocation takes # of institutions into account https://icpc.global/regionals/wildcards. So regionals optimize for slots by using this selection scheme.

      I mean when you consider its an online regional in the first place, what would be the harm of making the number of slots variable? Like taking first 400 or so by absolute rank, then taking the first from each remaining college?

      But last year Amrita selected top 70-80 teams on the basis of rank and then the first teams from each college, right? Also I think the number of slots last year was half of this year's, so I don't think selecting even the top 150-200 teams on the basis of rank will significantly reduce the number of unique colleges.

      Btw, a technical detail — the number of participants should be the number of people participating in the online round, and not the regional, right? The number of teams in the regional (i.e, 2nd stage) is a filtered out version. What should be considered is the total participation in that region, which is all the teams who registered for the first round. I'm not sure why this isn't the case here..

    Rev. 3   Vote: I like it +35 Vote: I do not like it

    I had this exact concern, but two things to note is that

    • The number of distinct colleges participating last year was around 400

    • The number of distinct colleges registered for Amritapuri last year was around 300

    So assuming trends hold that should be around 300-400 slots which will be taken by absolute rank.

    But still, it does suck that there is no exact cutoff rank defined in advance, it really should have been something like:

    • Top X by absolute rank

    • First from each college after removing first X

    • Fill rest by absolute rank from the rest

    which would have been more in line with the normal Amritapuri selection process :/

      You need to note that regionals have no entry fees this year, and 0 other associated costs... I do think that will increase the number of distinct colleges significantly.

        Yup, that is a reasonable point, and the major reason why I consider the second system to be far fairer.

        Furthermore, its an online regional where the number of spots aren't tightly constrained by any physical resource. They could always fix the number of teams qualified by absolute rank, and take the first team from each college beyond that.

        I'll probably scrape the registered teams list in a bit and try to get an approximation of how many distinct colleges have registered till now.

You mentioned that

Registration will end 10 days before the Preliminary Online Round

However as of the time of writing this comment, the Upcoming regional page on the ICPC site shows that over 80% of the online round slots have been filled. If the limit of 3000 is reached before this deadline will it be increased to allow more teams to register, or is it a hard cap?

    Some teams will have to deregister themselves to participate in other regionals, I think that will make more empty slots in this.

      That is true, but as long as the number of distinct colleges registered for Amritapuri doesn't get too close to 700, many teams from stronger colleges will favour Amritapuri. Basically its whether you think getting through on absolute rank or defeating nearly every other team in your college is the more feasible option.

      2. As far as I know yes. But please confirm at the above mail address

      I think it's the problem from the coach side. It was occurring because our coach has not updated his icpc profile information. But after he updated that the problem was automatically solved. So you can ask your coach to update his icpc information.

          What the hell? I should not say that but being such a prestigious contest ICPC should check for their scalability and performance issues.

          I know that at the last moment traffic is higher than usual but ICPC should have checked this.

          Their also not responding to mail.

          I hope they extend the deadline by a day or two. Balajiganapathi

          I am afraid, I can't help you. Unfortunately, the last date for registration has passed according to their website. I think you can try mailing them your concern and that you are trying to register for the last few days, maybe attach some screenshots for credibility. They should do something because these are errors on their part.

          P.S. I am not a coordinator nor am I associated with ICPC organizers in any manner.

    Balajiganapathi For Kanpur regionals we are getting the message "has already graduated" showing that our team is ineligible. One of our team members has his graduation set to July 2021. Clicking on "Revalidate" button isn't fixing the issue. What should we do? Can you you look into this, since the deadline for Kanpur regionals is quite near.
    I have also mailed manager@icpc.global about the same

We are forced to postpone the preliminary round due to the problems in the ICPC registration system. We're working on resolving the issues. The dates for the ICPC preliminary contest are yet to be finalized. The team is working towards providing you the best experience and mostly we will be able to organize contest within 10 days. Before that, we will also organize a practice session for you. Participants will soon receive an email with the contest dates.

      Dear Coder,

      Really bad to see this type of comment. Without knowing the real issue, comments like this seems to be really bad. we had to delay the contest because the data in ICPC Registration system was migrated to cloud and most of the teams faced updating the data, missing of data, etc. This was resolved hardly two days back. Wonder how you think and comment like this.

Dear ,

Greetings from ICPC Asia Amritapuri Regional Site!

Hope you are doing well & staying healthy.

We all are going through tough times in our lives. Education & work have been disrupted equally. I was trying to host the ICPC Regional in the month of July but got delayed because of some technical reasons. Now, the decision has been made at ICPC Headquarters to host the world finals at Moscow during the first two weeks of October. Chances are that the teams qualifying in the 2020 Regional (the current contest, to be held in August 2021) may be qualified for the Moscow World Finals. The contest will be held on August 14th 06:00 PM. In that case, we can have only one round of the contest to qualify for the World Finals to be held at Moscow.

Teams interested in participating in other sites in India are free to cancel the registration at Amritapuri site by logging to ICPC Foundation Registration system.

Teams solving at least one problem will receive t-shirt (for each member).

Please write to icpc@am.amrita.edu for any queries.

This is what we recieved. Ahh, one year of ICPC ruined for us.

      First of all, you should have all the facts to comment something bad about anyone.

      Qualifier problems were ready from last one month. If there have been no issue in ICPC global site, qualifier round for Amritapuri Regional would have been finished on 10th July.

      And guess what this would have been more problematic because now all other regionals don't want to have a qualifier given the short time.

      Lastly what do you think, the organising platform have any control over ICPC committee decisions? If you think so, I'm happy but sadly we don't.

      There is no notice till now about other regionals, and it seems like, yes they are merging the WF. But the worst part is that, for Indians, there is either WF or nothing. The regionalist tag was something we were hoping for as someone who has still a begginer compared to the WFinalists. Now its gone. And the worst part is that, all they had to do was organize 2 proper online coding rounds, for which they came up with their own website in order to collect our contact info and then send promotional Emails of their programs every other day, all that, just to end up with not even getting a proper regional round T_T

        What?

        1) ICPC Rounds are generally prepared by ICPC regional setters not the platform setters. Though everyone's ideas are welcome to be considered for ICPC rounds.

        2) Codedrills doesn't belong to Amrita sadly if thats what you meant.

        3) We collect user info only when a user creates an account on our website. Read privacy policy here. If ICPC regional wants the info, they anyhow get it from ICPC global system. Why would they need a new website for it?

        And we haven't added already received emails of few teams from ICPC system to our announcement list. And we won't add others as well which we receive for ICPC rounds. So your comment regarding data collection doesn't mean anything.

        4) I personally wanted to have a qualifier, requested many times but the decision from Indian ICPC committee is NO so can't do anything here.

        Thanks for replying. I'm sorry, but I'm still a little confused. The world finals of the previous year is supposed to be held in October. In the email you said:

        Chances are that the teams qualifying in the 2020 Regional (the current contest, to be held in August 2021) may be qualified for the Moscow World Finals.

        So, this "Moscow World Finals" is separate from the postponed world finals from 2020, but held around the same time? Or is it just that the regional toppers somehow get to participate in the postponed World Finals? It would be helpful if you could explain a bit more clearly.

  3. About the contest date of Kanpur regional?

  • According to this, the date is 16th August 2021.
  • According to this, the date is 13th August 2021.

      Teams who are selected for the onsite round will be charged INR 700.

      What does this mean?

To be honest ICPC India is becoming shit. I think, all the online rounds and regionals should be held on codeforces. I won't be surprised if there is a server error on Codedrills during the actual contest.

    I agree with the last point. Because they have never quite actually handled the amount of traffic equivalent to what will be expected for the Online Round. are you sure Balajiganapathi Vichitr ?

      We did perform extensive load testing on double the amount of expected load and have optimized our servers to handle the load. Do participate in the upcoming mock contest and let us know if there are any issues.

Quick sanity check, now that we're back to a preliminary round + regional round, the previously mentioned slot count (700) and team selection method (first from each college + rest by absolute rank) still applies right?

Also can we expect to have a final list of distinct colleges at some stage? I know there are rough lists people have generated by parsing the site, but some official numbers could give us better clarity on how many absolute rank slots we can expect would be nice.

    • Yes the selection rule which was decided earlier would apply now for Regional team selection.

    • You can send an email to Regional for the list of distinct colleges and absolute rank slots.

      If you do that, ExplodingFreeze then please do share that here too, so we can also know how much the competition is(just for curiosity and not that I fear competition)... Thanks in advance from all of us.

Can you also tell whether Gwalior-Pune and Kanpur-Mathura are holding 2 rounds (Prelims + Regionals) or are they directly going to send teams for the world finals? Also, how many world finals slots are there from each site?

    • First question has been answered already numerous times. Read here.
    • Number of WF slots are allotted only after regionals conclude so we never know until they announce with their weird calculations.

Hi all, we will be conducting a mock contest for those registered for ICPC Amritapuri (details at https://codedrills.io/contests/icpc-amritapuri-2020-mock-round). We strongly suggest you get familiar with the platform by participating in the mock contest and ensuring that your login works. Make sure you resolve any issues faced well before the main contest. We won't be able to resolve any login related issues that are reported later.

    Maybe you should drop an email to Kanpur site instead of asking it here. Find contact here. And also you should consider what their site says as they would update on their site first then ask ICPC global to update.

As problemsetters, what goes into the decision of choosing the allowed error? To me, $$$10^{-9}$$$ is very harsh.

        Rotate the axes by 45 degrees, the question now reduces to finding the minimum side length such that 2 squares of that length cover all the n points.

          Ah then we have the same solution. What makes it so that it must always be a multiple of 0.5 though?

            For at least one of the squares, at least one of its set of opposite sides should each contain a point. It can be proved by contradiction as we could shrink our squares if this property doesn't hold.

                Just take the sorted array from 1 to 100000, and for each index i, replace that position by a 0. Now move that 0 using each gap in the gap sequence by doing i%=g[j] successively, and if it is not able to reach index 0 at the end then count it in the answer.

Why does the form for the Kanpur-Mathura Site ask about "ICPC World Finals 2020 (at Moscow, Russia) in the month of October 2020". By the look of it, several fields are directly copy pasted from the form sent to last years Asia West finals participants.

Why does Gwalior-Pune's website still mention this:

This year because of current covid-19 pandemic there will be only one online contest to finalize the team participation for world final 2020.

World final will be held at Moscow in First week of October, 2021.

It is assumed that probable world final contestant has taken at least 1st dose of covid vaccine by 1st week of August and 2nd dose of covid vaccine by 5th September, 2021. If required Global ICPC organizers can help you to get 2nd dose after 28 days.

The teams that qualify through this year's regionals will participate in the world final in 2022. Teams for the October 2021 world final to be held at Moscow have already qualified. It looks like they are hurriedly hosting only one round instead of two based off of a misunderstanding.

    I think a further delay in hosting the regionals is not possible, as many graduating students might be starting/ have already started grad-school or jobs and it may be inconvenient for them.

      Amritapuri is hosting two rounds with its regional happening before both Kanpur and Gwalior-Pune. And anyway, the part about world finals happening in October 2021 is wrong, which is what I think caused them to keep one round in a hurry. Also I think many (most?) graduates have already started jobs or grad school.
