By Eddagdeg, history, 9 days ago, In English,

Hello everyone ! I'm fourth year software engineering student.I've been doing CP for three years .I learned many algorithms and I solved many problems but the problem is that I cannot do my best during contests for that I'm going to set myself a 30 day challenge :making virtual participation every day in a contest and upsolve all unsolved problems. so if any one remember a good round (quality of problems,gap of difficulty between problems)please share it with me. I'll update the blog every day to post my rating in the contest and let's see if this challenge gonna make me a junior tourist ^__^.

first contest:round 422 rank:1368

second contest: round 480 rank:1058

third contest: round 353 rank:1398

fourth contest:educational 80 rank:2045

5th contest: round 464 rank:308 (best rank I ever achieved ^___^)

6th contest: round 489 rank :269 :my best rank so far :)

7th contest : educational 42 rank:1002 :(

8th contest: round 476 rank:1449 :(

Good idea! I wish you all the best!

I think Div2 is the best difficulty for us, it has varied levels of difficulty, but maybe consider AtCoder ARCs for more diversity?

I don't think upsolving the entire round every day is reasonable, unless maybe you're doing div3 or ABCs. Maybe set your goal to upsolve 1 unsolved problem from each contest.

(I feel like the final problem from Div2 (or Div1) rounds is hard enough that it'd be tough to do one of those per day.)

Maybe I'm wrong and I should be more ambitious with my own problem-solving. :)

    yeah you are right,I'll focus on problems solved by atleast 300 I'll try to get out of my comfort zone but not getting stuck in very hard problems that won't be helpful .Thanks!

      For a stable expert who doesn't have any progress, I would say 3 to 4 problems in div.2 and Edu round with an "ok" time. For me, It could be A in 2 to 10 mins, B in 20 — 30 mins and C around an hour, probably D in one and a half hours.

    Imo if you have time, you should upsolve all problems from the contest you participate in, as it is your level contest, therefore your level problems.

      solving more B and C problems will help me to become faster and to get enough time for D or E problems

Seeing your graph, i am keen to know what changes did you bring in your practice methods/or any other signifact change in any thing else after Educational Round 46 (27-Jun-18) that led to such a steep rise as i am struggling despite significant amount of practice.. :)

I think Educational Codeforces Round 71 (Rated for Div. 2) is one of the best rounds I attended. Also it has a good quality interactive problem.

Good luck with that. However, setting a goal that is very difficult to achieve can become demotivating. I think that it's better to solve problems that you suffer from usually and to participate frequently in virtual and real contests.

    It depends. It may taken arbitrary amount of time to try to solve a problem without reading the editorial, but if the user decide to read the editorial and implement it then it's feasible.

Although other comment already recommended ARC from Atcoder, I think considering your current codeforces rating ABC might be more reasonable. ARC rounds have very difficult E and F problems, and these might be demotivating or frustrating, especially when a difficult problem you encounter actually turns out to be requiring more knowledge than thinking.

In contrast, ABC rounds have very easy A~C. D (older ABC rounds) and E, F will be somewhat challenging (I feel they are about CF Div.2 D~E) but it would certainly be more achievable goal.

As you wish to upsolve all the problems, Div2 contest might be a bigger challenge than you intended. (There are some 2700~ level problems in today's Div2.) ABC rounds will be in more reasonable difficulty and might help you be keep motivated by some sort of accomplishment.

I personally enjoyed ABC 131, 132, 140, 143, 144, 145. If you haven't tried one, note that Atcoder contest are shorter (100 min) in general, and you can use https://kenkoooo.com/atcoder/#/table/ for checking difficulties. Also Atcoder contest tend to have less story-based problem statements, and problems are more mathematically defined. (Though these varies round to round.)

Wish you all the best :)

Can you provide the link to the contests in your blog as you solve day-wise?
So that, others can also follow along to improve.

to post my rating in the contest

I thought you would post your rating change if you participated in the real contest... (you can use the Virtual Rating Change Calculator for that)

However, because the rating values change over time, it may not be very meaningful.

Without doubt,you will achieve your dream with this challenge.

In my opinion,Educational Codeforces Round 69 (Rated for Div. 2) is a great round,especially the D.(I became an expert in this round)

Best of luck, but upsolving all the problems in a single day might be very difficult, specially when some problems require prerequisite knowledge. If you want you can use this site.

I dont know too much, just enough to do A B and C quickly (if Im also lucky). I dont think my knowledge now can do task D well. As you said before, you had enough knowledge to solve all tasks for a div.2 contest and if you dont care too much about rating, what youve learned is more important, just ignore it, having higher rating doesnt mean that having greater knowledge (as my case). Also my training procedure is trying to do my best for first 3 problems (as fast as possible) and if problem D is not too hard (having diff <= 1900), maybe I can solve it on time (not sure, just 50/50) but if it doesnt happen and the task D is not too tough (having diff below 2100), I will try my best to solve it after the contest. That is my training technique, hope it helpful to you, also I will try my best to get to rating 1700 in next 1 month. Keep going and never give up buddy ^_^ , have a nice day and HAPPY CODING!!!
