Beta Round #5 — csacademy.com
By csacademy, 8 years ago, In English

Hello, Codeforces!

We are happy to announce that we're going to host a new contest at csacademy.com. From now on we're going to have a competition every two weeks, so here we go:

Beta Round #5 will take place on Monday, May/09/2016 16:00 (UTC). If you want to take part in this round you need to register before the contest begins. Just like the previous round, this will be a Div1 + Div2, with 6 tasks of varied difficulty.

Platform changes since Beta Round #4:

  • IMPORTANT: When the contest starts the page will automatically load the tasks and open the first problem for you. Please don't refresh the page, as this will probably overload the server.
  • We fixed the editor buttons bug. Now you can safely compile and run your code in the editor with no fear of the buttons freezing.
  • We changed the contests page to show local times (in addition to UTC).

Contest format:

  • You will have to solve 6 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.

We are curios to know how many of you use the online editor we provide. Let us know in the comment section below. Suggestions and feedback will be highly appreciated.

We still recommend using an updated version of Google Chrome. If you find any bugs please email us at [email protected]

Don't forget to like us on Facebook, VK and follow us on Twitter.

EDIT: The editorial is ready. Congratulations to all the users and we hope you had a great time. We are waiting for you at Beta Round #6 in two weeks.

    I think because it's beta. So they want to make sure everything is going right.

    The contests are authored and prepared by members of the CSA team. As it takes lots of time, work and inspiration for a round we can't afford organising them more often. We would love to host more competitions, but this would mean getting help from external problem authors.

    If you want to help us, participate in large numbers. When the community will be large enough we'll be more than glad to host your contests.

I really liked the problems of the last contest but I would love to have two divisions as the last three tasks were quite hard last time and I wasn't even close to the solutions.

But I think it might overwork you.? Good work. Thanks

    I agree, last time it was too difficult for a 2 hours contest. The tasks will be a bit easier in Beta Round #5.

    Unfortunately, we don't have enough users for two divisions. For a while the format will not change, but we will adjust the difficulty of the tasks.

I like to code in Vim and I find it rather hard to copy-paste into code editor, will you have an upload button?
