Teams Going to the 2023 ICPC North America Championship
By IanDeHaan, history, 22 months ago, In English

Most North America ICPC regionals have been held. While we don't yet know who is going to NAC, it's reasonable to guess that the slot distribution will be similar to last year. So here is a list of teams who qualified for NAC assuming the same distribution. Note that all regions are guaranteed at least 3 slots, and I would be relatively surprised if any region received less than 4.

Update: It looks like an official list has been posted here. I've updated the tables below in accordance, with the exception of Pacific Northwest, which has some irregularities.

Update 2: UC Davis now appears on the list, so everything seems normal now. 48 total teams invited.

Update 3: Stony Brook University and Northeastern University have been added to the list, for a total of 50 teams. I expect there will be no more additions beyond this.

If you know the codeforces handles of any team that is not yet filled in, please let me know so I can add them.

    I am actually curious that if school can choose which team to advance in NAC. Base on NENA board, MIT3 actually beats Mex Foundation. So now it seems to be ok?

    The ICPC website now says that MIT3 has qualified, not Mex Foundation, so I've removed these usernames from the list. If this is in error (the ICPC site is wrong), please let me know.

Regarding the remark on the slot distribution at the top, I was told that the rules for US South were as follows:

  • Each region's top three teams advance
  • Next three teams from the US South combined combined scoreboard advance

I do not know how it is being done elsewhere.

    Very interesting. Hopefully there will be wildcards in addition to this, or else South will end up with less slots than last year.

How did you derive that UNC CH was going? Having 6 slots for the midatlantic seems like a lot.

    Because it had 6 last year, and the post says it is based off last year's distribution.

    This is assuming the same number of teams are being invited as last year. Last year, there were six teams invited from MAUSA and fourteen total from the South; inviting all first teams that solved five or more problems, which includes UNC, leads to six MAUSA teams and fourteen South teams in total. That said, these slots are not guaranteed--we were promised three teams from each region plus three wild cards from the overall scoreboard, and while ICPC has been known to add extra wild card slots frequently, this guarantees qualification only for the top three teams from each region and Lafayette, Rice, and Lehigh, with UNC and FIU's slots not confirmed.

      Out of curiosity, what happened to Swarthmore? We (the unc team) were sort of expecting yall to come in first place given your history of domination lol

        My teammates and I all ran out of eligibility, so the current Swarthmore teams have no overlap with the team that made WF for the last three years.

        Hope NAC qualification works out for y'all!

    "There will be no NADC this year, and I doubt it'll resurface in the future. Teams will advance from Regionals to the NAC, with no intermediate contest. Many regions are discussing merging into conferences similar to the NADC divisions, but they will be entry-level contests." -David Van Brackle (director SEUSA) on Discord

    Haha, that was my whole team last year too.

    I hope y'all try out codeforces contests a bit before NAC. Last year at NAC I was somewhat intimidated by how much codeforces was discussed.

    Last year almost every night after dinner a lot of people played something called "lockout" on some discord bot, basically, it picks around 5 random codeforces problems and the two participants race to solve them first. Codeforces problems are kinda different from a lot of ICPC problems so if you have not done codeforces it is pretty difficult. Last year I tried to play one round but it was entirely one-sided.

    I say this to say, you may have more fun at NAC if you give CF a try.

    Personally, I am hoping this means two more teams have yet to be added. For context, in both ECNA and NENA regions, problem L had a typo where during the contest, the problem said $$$n \leq 1000$$$ instead of $$$n\leq 100$$$. My team (Northeastern) placed fifth in the NENA regionals due to not being able to solve problem L because of the accidentally-too-hard constraints in the problem (

    we had this solution

    but did not submit until the very end due to the fact that our solution was over 3 seconds when tested on a random $$$n=m=1000$$$ case), so I am hoping the fact that there are only 48 teams on the list means we still have a chance to be added.

Congratulations to all the teams that made it. It does suck that only 3 three teams qualify from SER. I was hoping they would add one more team from the South region, was really hopping that we'll make it this year. (FIU)
