Hello CODEFORCES! I'm finding a problem with improving(I want to higher my rate) while keeping up with my life(studying ,sport , hanging out...). I started to use USACO GUIDE , I know It's helpful ,but I someti
Also,I know that this graph doesn't by any means affect my problem solving skills or my rating. But it still looks much much better and much more self-convincing. Especially when I solve a higher rated problem, come back to my profile to see the graph improve. If I have 200, 800R ...
I start my intuition byimaginingthe problem in my head with something I am familiar with (a plot). Because this all happened in my head, you will see thatthere is almost no formula in my head. Or, as I would like to put it, ...
Hello, I am Gustavo from Brazil. I would like some tips to help me improve. Currently, I can solve problems rated around 800 in Div. 4. I can solve problems A, B, and C in Div. 4 contests, but no more than that. In Div. 3, I can sometimes solve problem A, but I don’t ...
Open AI's new model claims to achieve 1800+ rating. I would assume in the near future, AI could achieve 4000+ rating and beattourist. Although I'll mark this day as the day when AGI comes, it will pose an existential threat to Codeforces!
+ If it's an ACM contest, you have to reach a rank that low enough. If your rating is so low that it's increasing even you just solve one problem, then you should finish it in a score of 0. + Or it's an CF contest, you could finish the contest without any AC. But if you...
In short, mostly you only need to use codeforces (no matter what contest you're training for), find a rating range where you can solve around ~30-40% of the time on your own, and just grind down the problem set tab in reverse order of id (the default sorting). Also take part in...
Yesterday some guy posted a blog about accidentally submitting a solution to a problem in the most recent round meaning to do it after the contest ends. He entered a competition, lost 233 rating and then requested to make the contest unrated to him. As it is already clear to probably every...
I see a lot of newcomers struggling to use the website to it's fullest, so I decided to write a blog that has all important information about how to use Codeforces in a single place. I will update it with time, so feel free to write your suggestions/questions in case I missed someth...
Can someone help me by giving me feedback on how to improve my rating? I am feeling stuck, I am unable to improve myslef, which results in making me stuck in Grey. This is also making me a bit frustrated. What I do for practice -> I am solving thisSheetcurrently. I am currently ...
