Hello Codeforces!

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 5th.

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 for the Qualification Rounds will be open on March 23rd.
