Rising-coder's blog

I've started solving 1400-Rated problems about 10 days ago but I'm really struggling with them.
Most of them I needed to read the editorial to solve or I ended up not solving them at all.

Should I just keep going or should I go back to easier problems(1300-1200-etc) ?

Start solving from 1000 then step by step increase the level.

      Don't have some sort of a quota like "Once I solve x problems of this difficulty I can move up." Just solve problems that you find interesting for yourself and that you can solve, but not immediately. So if after 10 problems you feel like raiting is too easy for you, go up. If after 100 problems that raiting is still interesting for you, then keep doing it.

Return back to 1300 a bit, if you find yourself good at it, then go to 1400 problems and forget that they are harder problems. The biggest issue about upgrading is thinking that "OK this is a problem from a higher level, it's harder to solve so I will see the editorial", thinking like this is bad bro :(

Sometimes official problem rating doesn't represent their difficulty FOR YOU. For example, today I solved a 2900 rating problem 189217482 by just finding pattern for small cases.

Official rating of a problem is decided by how much people solved it during the contest (and the rating of who solved it), so some problems (like 1775E - The Human Equation) has a high rating just because it's letter E or F (whose solution can be implemented by any beginner).

Rising-coder, most of the times its just the lack of patience. I also stop putting energy into a problem if it is a little too hard, requires a bit of thinking and go watch youtube shorts or tik tok because it takes less energy.

Honestly thinking on a hard problem is not as entertaining to me. I'd rather go do something else.

what suprises me is that , you after 13months were still consistant and reached almost 1900+ rating, proud of you man, you are crazy good

In my opinion, the rating serves merely as an indicator and nothing more. Often, not all problems receive an appropriate rating, which usually depends on several factors:

  1. The number of people participating.
  2. Some problems involve cheating, leading to their rating being lowered.
  3. The arrangement of problems in the competition. It's possible for someone to struggle with a seemingly simple problem due to a lack of idea, preventing them from progressing to the next problem. Additionally, there's a psychological aspect where some people believe a problem's difficulty is tied to the number of participants.

Furthermore, one's percentage of solving any problem at a given rating won't always be 100%. Mistakes by even Legendary Grandmasters (LGM) can occur, such as in problem B or even C(wait um nik says fuck you).

Ultimately, progress in solving problems at a higher rating often contains ideas that also apply to problems at a lower rating, albeit with some variations. This allows for encountering new ideas while reinforcing older ones. It's uncertain what's possible, but as "pupil" says to candidate master, it might hold true.
