Hello Codeforces!

Different people will have different preference and style of making new problems. So maybe there is somebody whose problems are somehow to your appetite.

So Let's discuss some about problemsetters. Who is the best problemsetter in your mind? Why? Which kind of problems are prone to be made by him/her? Feel free to comment below and recommend innovative problems at the same time.

For me, My choice is Errichto. I think some of his are really creative and full of ingenuity like 573C,611H. (Maybe it is one of the reason he can be the topest contributor:P)

I like contests made by amd, his problems are more about thinking rather than typing

Errichto is the best. He sets so many problems on different platforms and almost all of his problems are beautiful and unusual in many ways. It even makes me jealous (in a good way): I can come up with 10-20 not bad problems in a year and he does it in a month or two. And his problems are still better than mine!

There are some problemsetters who set many problems but their problems all look the same. Errichto is the opposite.

I really enjoy old Warsaw U contests and Errichto keeps his university tradition of very interesting high quality problems.

My favorite is rng_58. His problems are both creative and unusual. If they use a technique, it seems natural to the problem and not a problem written around that technique. Most of his problems have an analytical or ad-hoc element to them. This makes them very fun to solve.

My favorite is Xellos. He writes really nice and non-trolling problems, good editorials without unnecessary dank memes, and he even honored Rudolf Lipschitz in one of his problems, although he made an unfortunate typo, making his surname sound like shit.

Arpa had conducted only one round but the quality of questions and editorial was really good.

      actually, "Arpa’s letter-marked tree and Mehrdad’s Dokhtar-kosh paths(Hard)" is the longest problem name in codeforces.

In general, I appreciate the problems from CSA Rounds. Link They don't publish their problemsetters. Consequently, I don't know who are the authors of most of the problems. However, somebody told me that this problem was written by Wefgef. I really enjoyed solving it and other tasks from the same author.

    Agree, I sometimes enjoy a lot when solving problems in CSA, they are really concise and interesting, I recommend it to lots of my friends:)

sugim48. He sets many problems in "Atcoder Grand Contest" and Topcoder, and his problem's quality is always high (Implementation < Concept).
My favorite problem of sugim48 is, AGC 004 C — And Grid and AGC 006 C — Rabbit Exercise.

    I think in Atcoder, many Japanese problemsetters made many unusual creative problems which require more thinking but implementation. And including your contests:)

Lewin since my best performance so far was on one of his contests. His problems tend to be quite mathematical which I like.

I will go with Petr and Marcin_Smu (though he only set problems on Polish contests). And once again, hats off to andrewzta :). Few others that are not at my very top, but I am always sure about problem's high quality when they are problemsetters are Arterm, Endagorion, Errichto, lewin, cgy4ever, guys setting at AtCoder and probably few others that slipped my mind. I also really like my own problems xD.

      Yeah, I am also looking forward to that event ;p. I got some ideas that could suffice to create contest, but I can't find sufficient will and time to prepare everything :P.

    I would like to ask you about the strategy I have followed , that I have been practicing on Div2-D,E ??

    1-practice in order of level in general. 2-practice in order of level but for the best problem setters only.

    Do the second step Will improve my thinking better,faster and save time What is your opinion for this point ??

      no. i think you should practice some classic problems, while good problemsetter is making unique and not classic tasks.

I love Errichto's problems. He has made me fall in love with bears! I find Endagorion's problems quite interesting. Besides them, I also like Sereja and KAN's problems.
