Round #37 (Div. 2) + Special Prizes
By csacademy, 7 years ago, In English

Hello, Codeforces!

We are going to host a new contest at csacademy.com. Round #37 will take place on Wednesday, July/12/2017 15:00 (UTC). This round will be a Div. 2, meaning that the rating change will only affect users with a rating below 1675.

Special prizes

This round will have 3 special prizes consisting of private coaching lessons with our contest coordinator, wefgef. Each lesson will be conducted on Skype and will last for 1 hour and 30 minutes. You can find out more details on the contest page.

Contest format:

  • You will have to solve 5 tasks in 2 hours.
  • There will be full feedback throughout the entire contest.
  • Tasks will not have partial scoring, so you need to pass all test cases for a solution to count (ACM-ICPC-style).
  • Tasks will have dynamic scores. According to the number of users that solve a problem the score will vary between 100 and 1000.
  • Besides the score, each user will also get a penalty that is going to be used as a tie breaker.

About the penalty system:

  • Computed using the following formula: the minute of the last accepted solution + the penalty for each solved task. The penalty for a solved task is equal to log2 (no_of_submissions) * 5.
  • Solutions that don't compile or don't pass the example test cases are ignored.
  • Once you solve a task you can still resubmit. All the following solutions will be ignored for both the score and the penalty.

Hey guys,

We had our first wrong problem in a round today, sorry about that.

We're sorry to not reward the people that did well in this round, but making it rated would be unfair to contestant that lost a lot of time because of the broken problem.

We want to propose a freeroll rating round, that goes like this: The broken problem is removed from the contest. We then see what rating everyone would have had. If your rating would have increased, we give you the extra rating. If your rating would have decreased, it might be because you spent too much time on a broken problem, and you keep the same rating as before.

Please let us know what you think about this approach here and especially on our forum if you were a competitor and feel this would be unfair.
