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.

    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.

          Look my case was a bit different because:- 1)I was not not using my college's official professor's ID 2)The team made by me was not from a coaches account.So degree info was not coming in my profile 3)I was not filling my institution name properly and degree tab was not appearing

          So what I did was 1) I asked for official ICPC ID of my professor 2) Then I registered the team from that account with a different name. Because that name was not available till then.I don't know why but it worked 3)after I made the team form my professor's official ICPC ID then degree info tab also came and I was able to fill my degree details(which was coming coming earlier).

          Moreover the site is very slow Sometimes various errors appear like 503, object object etc when we save our details. What i did was I kept on pressing that save button again and again.I also logged out few times and logged in again so that my information can get saved. Finally information got saved. In the last my team was declared eligible.Though the status is still Pending right now,but I assume it will get Accepted in few days.

          I don't know whether it is necessary or not to use college professor official email ID or not but it worked for me atleast.

      1. Yes 3 is required from same college. Same stream is not required — I had participated in one of the regionals with team mates from CS while I was not.
      2. As far as I know yes. But please confirm at the above mail address
      3. Yes, I had formed a team with bachelos students when I was doing masters
      4. Yes

      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 think it's a common practice (and rightly so) to do important things early to avoid last moment issues.

          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.

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.

Balajiganapathi Vichitr anandoham I just want certainty on one thing, now that it's certain we are gonna have a single contest and world final spots would be allocated based on that itself, how many World Final spots would be allocated at Amritapuri?

Because there used to be multiple spots till 2018, but last year there was only one spot and others were moved to Asia West Finals last year, but then this year doesn't seem like Asia West is gonna happen either, so can someone please gimme an official number of World Final spots?

Also the mail states the contest would be on 14th of August at 6:00pm, I wanna confirm, it would be an ICPC style 5 hour contest right? (Because most 3 hour contests are just a race)

    Only if you want to register in two other regionals. The rule is: you can register for at most two Regionals. In case you want to participate in Amrita and one another regional then do not cancel.

Some Doubts:

  1. Are there any updates about other regionals, apart then Kanpur and Amritapuri regionals?

  2. Also, is the Kanpur Regional going to happen on CodeDrills?

  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.
  1. Is the contest going to be 3 hours or 5 hours?

  2. What are the setup requirements? (I hope appropriate measures against cheating has been taken)

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.

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.

Balajiganapathi
Vichitr
I wanted to seek help on the following issue.

My team (registered for Asia Amritapuri First Round Online Programming Contest) has been accepted and was eligible up until recently but yesterday (30th July 2021) I found the status as predicted ineligible with the log message saying that I compete for another university this year.

I remember that I registered (on the Codeforces platform) for the ICPC Challenge powered by Huawei held on Codeforces (link) and my Codeforces ID is connected to my ICPC ID, but I am sure that I didn't explicitly register for the contest from icpc.global but I found a new team (name: " lonewolf ", registered for this contest from " ICPC University ") on my ICPC dashboard recently, even though it wasn't there for at least a month after the contest ended (30th May 2021). I have no idea how it automatically selected a different University when I have added my actual University name in both ICPC profile as well as Codeforces profile.

Also, even after I self-cancelled that team which was registered from ICPC University status of my team for ICPC Amritapuri didn't change (it's still showing predicted ineligible).

Please help.

Thanks & Regards

            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 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.

      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.
