How to practice on Luogu?
By Abito, history, 4 hours ago, In English

Hello. If I want to practice on Luogu, is there something similar to rating of problems here? How should I start solving? It's hard to navigate the website so sorry for asking

Register a Luogu account and solve problem using vjudge. Vjudge is in English and it has a translation function based on ChatGPT. So you dont have to learn Chinese.

Here is the difficulty of the problems. Different difficulty has different font color. In short, red < orange < yellow < green < blue < purple < black, while gray stands for the difficulty isn't set.

I think the web translation tool that comes with your browser will be of great help to you.

    Hi, what would be the estimated CF rating equivalent for each problem difficulty color in Luogu?

      Red/Orange: *800 — *1100 Yellow: *1200 — *1500 / *1600 Green: *1600 — *1900 / *2000 Blue: *2000 — *2200 / *2300 Purple: usually >= *2400

      I'm not sure whether it's right enough.

      (However, I feel it a bit hard to strictly distinguish the difficulty in Luogu, because it doesn't have tag in numbers (such as *2500). So it could be a bit ambiguous. For example, a few purple problems are easier than some blue ones. This happened more often among low-difficulty problems.)

      Maybe it is like this:

      洛谷(luogu) 入门(red) 普及-(orange) 普及/提高-(yellow) 普及+/提高(green) 提高+/省选-(blue) 省选/NOI-(purple) NOI/NOI+/CTSC(black)
      CF 800 900-1100 1200-1500 1600-1900 2000-2300 2400-2900 3000-3500
