Hello, Codeforces!
We are going to host a new contest at csacademy.com. Round #68 will take place on Wednesday, February/07/2018 15:05 (UTC). This round will be a Div. 2, affecting users with a rating below 1800.
Facebook event
Recently, Facebook has reintroduced the possibility of recurring events. If you choose "Interested" here, you will be notified before each round we organise from now on.
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.

CSA Round#68 is partially overlapping with CF round#461. I like contests on both the platforms. But this time I can participate in only one :(
As far as I know, the round of CS was declared earlier. :/
We would appreciate it if Codeforces would respect our established time and day, Wednesday at 15:05 UTC. Thank you.
I have moved today's round 40 minutes later. Though it would be helpful if you can schedule the contests beforehand if you want some specific time, because I can't keep in mind established time for every platform. I check clist.by each time before scheduling contests, and make sure it is not occupied yet.
@csacademy, How about it, there are so many people who wants to take part in both the contest,,,
Usual timings for contest are between (14:00 UTC to 19:00 UTC), but timings on CSA are bit inconvenient for other platforms,
How about changing timings for CSA USUAL contests on Wednesday to 14:00 UTC ?
Allow me to disagree.
There are not nearly as many platforms so that the contests are held every single day of the week. There's always a free day for each platform.
CSAcademy already surrenders the best days (Saturday and Sunday) to other platforms, I don't see why it's necessary to also surrender the best time slot (this slot was decided to be the most convenient to most participants by public polls on CSA).
Also, as a side note, I understand that 14:00 may be better for you and some other people. But there's a nice example we have, topcoder, that tries to hold contests in different time slots. While commendable, it just doesn't seem to work (take a look especially at contests held at 1am UTC, it's just a waste of problems at this point, literally 0 people participate).
Is it really good to turn the programming contest into math course ? problem Sliding Product Sum
