Hello Codeforces!
We (SHZhang, antontrygubO_o, JohnVictor, duality, awang11, 79brue, codetiger927, bensonlzl, popkarsd, flamestorm, ETK., GideonB, kingofpineapples, czhang2718, rqi, eyangch, xGaz_), current students at MIT (and me), are excited to announce our new contest — the MIT Informatics Tournament 2025 Spring Invitational!
The invitational will consist of three individual contests: two Qualification Rounds and one Final Round. The top 400 from Qualification Round 1 will qualify to Qualification Round 2.
Qualification Round 1: 11am-1pm ET on April 6th.
Qualification Round 2: 6:30pm-9pm ET on April 12th.
For the Qualification Rounds, we expect a difficulty distribution roughly ranging from Div. 2 A to Div. 1 E.
The top 16 US and top 8 international contestants will qualify for the Final Round on May 3rd. The day of the Final Round is filled with exciting activities such as fun tours around Boston, a fancy banquet, exclusive meets with our sponsors, and solving super cool (and hard) problems! We will give capped reimbursements for travel and lodging.
Registration is open at https://mitit.org/Registration, and we have started reviewing and accepting participants. For more information, check out our website.









Man only if this was during CPW.....
Seems like Round 1 conflicts with a Div 1+2?
Thanks for bringing this up, we've changed Round 1 to be on April 6th.
Thank you, this is great news!
I tried to register, but it seems the registration page is still saying "Register for the M(IT)^2 2025 Winter Contest".
Thanks.
antontrygubO_o Can you clarify what US and international contestants mean here? E.g.,
Hey it has been few days since I registered still it says your status is in review When I visit my profile page.Can you guys help me out??
I would greatly appreciate it if you could provide more details regarding the maximum reimbursement amount covered for international contestants, thank you!
Hi! These details have not been full made public yet. We intend to reach out to each finalist after the second qualification round and adjust our reimbursements to be the most reasonable for having them come to MIT.
Resolved.
The problems are published on the gym.
Where is the editorial?
Here it is
How to write checker for A?
Maybe using a binary search in Python?
The round 2 problems are now available on the gym.
