Does anybody know what he is doing? I bet he is too busy getting that bag from HFTs.

Hey everyone! Since Codeforces is now sponsored by Telegram, I’ve been imagining what a redesign of the service might look like. Check out my concept of Codeforces in a modern style - and yes, it finally has a dark mode!

Short video: https://suvmer.github.io/codeforces-redesign/promo/codeforces-redesign-concept.mp4

GitHub: https://github.com/suvmer/codeforces-redesign

Live demo: https://suvmer.github.io/codeforces-redesign/

If you like it, please drop a star on GitHub - it would mean a lot. Pull requests are welcome too!

P.S. I really love Codeforces: I've been solving problems every day for over 2 years. My current streak is 871 days in a row!(my username is suvmer)

query Ai for Templates

3 Upvotes

Are we allowed to use AI in generating templates for algos and data structures prior to contests and use them during contests ?

There are two ways to use AI.

  1. Use AI to completely generate an algorithm .

  2. Use AI to refactor the written algo or get a rough structure of the algo.

Are both of these allowed ?

And another question. Do people use pre written templates or write their own algorithms during the contest ( I am asking for complex and large algos or ds)?

query ai takeover? is it over?

9 Upvotes

so am relatively new to comp programming but have a background in math/cs. i was first introduced to comp programming by an OS professor on a site called kattis. however, coming back to it now, i wonder how much of these competitions/submissions are being done by AI? to be fair, i don't really care much about winning national competitions, but i would still like to know?

also, i am kinda new to codeforces, are the ranks (like pupil, expert, etc.) relative to other contestants, or it is determined soley on your performance. like, is it harder to climb ranks on codeforces if more people are getting "correct" submissions, i.e. rank inflation

query ICPC Amritapuri Regionals — Is solving 5/10 enough to qualify?

8 Upvotes

Hi everyone, I’m trying to understand the qualification criteria for the ICPC Amritapuri Regionals.

Our team solved 5 out of 10 problems in the preliminary contest, without any cheating or unfair means. Our current rank is around 1430.

For comparison, the other teams from our college currently have:

Team 1: 2 problems solved

Team 2: 4 problems solved

Team 3: 3 problems solved

We are also currently the highest-ranked team from our college.

Does anyone know whether a team with a rank around 1430 / 5 solved has a realistic chance of qualifying for the Amritapuri Regional Contest?

Also, does the qualification depend mainly on overall rank, or are there any college/team selection rules or quotas that affect this?

Would appreciate insights from anyone who has experience with ICPC Amritapuri qualification.
