I believe a system which preserves the mean will be inflationary: as Codeforces becomes more popular, it's likely to welcome a lot of weaker members, so we should want the average rating to decrease. Perhaps the top should be allowed to increase very slowly, as the state of the art ...
Hello Codeforces! I got some interesting tricks to share with you. 1. a_i := (a_i + x)%mod Range Updates, Max Range Queries Apply usual range addition, but after each update run the following code:void normalize(int l, int r) { while(getmax(l, r).max >= mod) { set(getmax...

beforemasters) will be able to register for such rounds to participate officially, their rating will be updated based on the results of the round. We do not plan to increase the complexity of Div. 2 rounds. Practice shows
but what does it mean1300 or 1400 rating problem`` ~~~ what is the difference when we increase a 100 rating point ~~~ I am asking this because many time many old problem rating is very high but actually the solution they contain is very standard <: Atlast...
What can be a better approach to increase my knowledge and problem solving skills? What are your suggestions? Should I try practicing on other judges too as I only give contests on them till now? Though I see most of the problems on 1000~ solutions in problemset are Div2D yet I sometime...
Update: I got now as well the right solution for Problem D, after explicitly asking GPT to optimize the code for speed. https://codeforces.com/contest/1791/submission/197627585 → Reply ivan100sic 23 months ago, # | +54 I don't think LLMs will ever beat humans because they learn...
If you half-solved 3 problems but still wouldn't be able to do it on your own because you simply relied on the editorial, then in my opinion you're better off struggling on one problem and really getting it.
Hi guys! As I mentioned on previous contest I'm working on tool that predicts rating changes. I'm happy to present it now! A huge amount of your nerve cells die every time when you wait for a rating update on Codeforces. Stop this! From now you could use this service, it calculates...
Firstly, I think Codeforces should not increase div2 upper limit. The demerit is obvious: if only 2% of active user is div1, many people will lose hope to go into div1. Many people think "In div1, we cannot solve many problems, risk of getting 0-points". I can understand. That's...
