What is this

This project is an issue tracker for codeforces instance of IOI problems archive.

What should I do here?

• Help with problem materials
  • Pull request with fixing typos in statements
  • Provide missing statements in Russian
  • Provide statements in other languages, if you are ready to commit to doing that for a significant amount of problems
  • Pull request better validators (e.g., validate groups or add them to problems where there are no validators)
    • Most new problems had validators in the archive, but they are not polygon-compatible. Adapting them should be easier than writing new ones.
  • Send generators of better test data to issues
    • Do that only for problems containing validator.
    • Do that only for problems with subtasks, as otherwise, it significantly changes scoring
    • If the test is valid only for some subtasks, the validator should support validating subtasks.
• Report misconfigurations of codeforces problems with issues
  • Inconsistencies between statements and problem materials
  • Missing materials
  • Wrong scoring
  • Wrong subtask for some tests
    • Best way to report this is to provide a validator that supports groups for the problem.

Please, if you plan to make some significant effort, arrange it in advance with me. I can't guarantee that every work will be adopted.

What shouldn't I do here?

• Ask for help with solving problems - use codeforces forum or read editorials instead
