Codeforces Round 1006 (Div. 3)
By IceHydra, 33 hours ago, translation, In English

Hi everyone!

ne_justlm, itz_pabloo and I would like to see you as participants of Codeforces Round 1006 (Div. 3), which starts at Feb/25/2025 17:35 (Moscow time).

The round will be held according to the rules of educational rounds. Thus, during the round, tasks will be tested on preliminary tests, and after the round there will be a 12-hour open hacking phase (we really hope that not too many solutions will fall during it).

How the next announcement is made:

  • this is where copy-paste starts,

here is your text, icpc rules, etc.

  • this is where copy-paste ends.

You will have 2 hours and 15 minutes to solve 7 problems. The penalty for an incorrect submission will be 10 minutes.

We remind you, that only reliable participants of the third division will be included in the official results table. As it is written on the link — this is a necessary measure to combat unsportsmanlike behavior. To qualify as a "trusted" member of the third division, you must:

  • take part in at least two rated rounds (and solve at least one problem in each of them),
  • don't have a point of 1900 or higher in the rating.

Regardless of whether you are a trusted participant of the third division or not, if your rating is less than 1600 (or you are a newcomer/unrated), you may choose to participate rated or unrated.

We would like to thank MikeMirzayanov for the Codeforces and Polygon platforms, and Vladosiya for incredibly cool coordination of round preparation.

As well thank you very much we would like to say to Kirill_Maglysh for his huge help in creating this round.

Also thanks for our testers:

As a tester I tested the first Phystech Lyceum (our school) round. I found some problems interesting, so I recommend participating!

As a tester, I have a proof that upvoting this comment will lead to positive delta. But the proof is too long to fit the margin.

7 problèmes à résoudre en 2h15, avec une pénalité de 10 minutes pour chaque erreur. Si t’as déjà rêvé de rager devant un bug à la dernière seconde, c’est le moment parfait.

Mon objectif ? Réussir au moins un problème, histoire de ne pas pleurer en relisant mon code après coup. Bonus si j'évite de tomber dans un piège bien vicieux.

Que le karma des AC soit avec moi."

    hhhhh, enfin quelqu’un qui comprend la vraie douleur du competitive programming ! Entre les erreurs bêtes, les tests cachés et les cas tordus, ce round promet d’être un grand moment de réflexion… ou de désespoir.

    Mais bon, tant qu’on ne finit pas avec un score de zéro, c’est une victoire. Bonne chance, que ton code compile du premier coup et que les WA t’oublient !

Recently, the use of reasoning LLM models has impacted CF rounds, as more submissions are getting AC than usual due to increased AI-assisted problem-solving. This raises concerns about rating inflation and the integrity of contests. Implementing defensive measures against it is necessary, but not an easy task. Let's see how things unfold.
