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. In 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.

    Amrita college changed the dates (with some input from me) :)

    Sad to hear about the situation, hope things improve soon.

    Take care and stay safe everyone!

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..

    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 :/

      Probably a silly question, but how did you estimate the number of distinct colleges that participated last year?

      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.

Balajiganapathi can you create an option to give virtuals on codedrills so that those who have missed a practice contest can still give?

Balajiganapathi, can you please tell us how do we register our team for Amritapuri Regionals? Because on ICPC Website the last date for registration was 10 June 2021, which conflicts with the last date of registration given on this link which is 20 June 2021. Please help us. Our coach's screen while doing registration is like this.Image

      No, on the contrary they fixed it ASAP as soon as I contacted them on Codedrills Discuss Platform too. Coordination between them and ICPC must be nice to do this quickly. Thanks.
