In order to resolve ties, a non-deterministic tiebreaker problem (i.e., scored with a continuous/non-binary) will be released to all competitors with perfect scores in the overall contest on Sunday, May 14th at 12:00 PM. Solutions will be due one week later on Sunday, May 21st at 12:00 PM.
Qualified teams will receive an email by Saturday, May 13th at 4:00 PM EDT to confirm their email address. If you are a team with a perfect score and have not received an email by that time, please email firstname.lastname@example.org.
We have added more prizes! Check out the prizes for more details. Teams with perfect scores in both rounds will be contacted soon to administer a tie breaker for the overall contest. All winners will be officially confirmed after the tie breaker has ended.
We are currently working behind the scenes. Please wait for further updates, which will be posted here later in the week.
