Rated External Contest
These are the guidelines to be followed if you want your contest to be Rated:
  • Problem Gradient:
    The contest should have something for all users of the platform. So, you need to ensure that a good spread of the problem difficulties is present.
    • If the contest is for only Division 2 users, there should be:
      • at least 1 Cakewalk problem,
      • at least 1 Simple,
      • at least 1 Easy,
      • at least 1 Easy-Medium, and
      • at least 1 more problems which is Easy-Medium or harder.
    • If the contest is for only Division 1 users, there should be:
      • at least 1 Easy problem,
      • at least 1 Easy-Medium,
      • at least 1 Medium, and
      • at least 1 which is Medium-Hard or harder.
      Note that this is option is not preferred and it better to add a couple of easier problems and make it a combined contest.
    • If the contest is combined for both Division 1 and Division 2 users, there should be:
      • at least 1 Cakewalk problem,
      • at least 1 Simple or Easy,
      • at least 1 Easy-Medium,
      • at least 1 Medium, and
      • at least 1 which is Medium-Hard or harder.
    If you are unsure what the various difficulty levels are, please refer to this.
  • There should be one Point of Contact (PoC) from the organizing team, with whom the CodeChef team can interact and who will take responsibility for the entire contest.
    The PoC should satisfy at least one of these 3 conditions:
    • They should have a Combined Codechef Rating (current) >= 1700 and should have participated in at least 10 CodeChef contests. (OR)
    • Codeforces Rating (current) >= 1900 and should have participated in at least 10 Codeforces contests. (OR)
    • Topcoder Rating (current) >= 1500 and should have participated in at least 10 Topcoder contests.
  • All the problem ideas and solution outlines should be sent to the Codechef team at least 10 days before the contest, for review.
  • Once approved, all the problems should be made ready, at least 7 days before the contest.
    This includes:
    • Problem statements
    • Test-data
    • Editorials: Please look at this for editorial-specific guidelines.
    • Test-data Generators
    • Two solutions for each problem, written independently by two different people.
    • Validators (codes which assert that all the constraints are satisfied in the test-data)
    Only after all these have been submitted and reviewed, will the contest be announced as being Rated and promoted.
  • The organizing team, along with the PoC should be online during the contest and respond to the various comments.
  • Detailed editorials should be published as soon as the contest ends.
  • Plagiarism Test: After the contest, we will share the MOSS results with the organizing team. They will have to go through it and decide the threshold percentages for each problem. This will be sent to us, and we will review this once. Then we will disqualify those participants who fall within this %-age.
