How to not get sleep deprived after playing a codeforces round?
By culver0412, history, 2 years ago, In English

I am a purple coder, who desperately want to get to orange in order to write a CF round. Sadly, despite my attempts, I still haven’t succeeded.

During summer, or if the next day does not have school, I can stay up late (my time zone is GMT+8) and participate in the round. But as I become increasingly desperate, I want to find a way to participate Round 821 also, which is on a Monday, and not get sleep deprived for the next day at school. The more rounds I participate, (hopefully) the quicker I can become orange.

Now, I want some suggestions for me to be able to participate a CF round and still be able to wake up early for the next day of school and not doze off during lessons. Can anyone give any suggestions?

I'm at GMT+9 and I had to start choosing the rounds I want to participate carefully. If it's not a problem for you to be a little sleepy the next day, then take the round, if it's going to be a problem or you've been doing too often then skip the round. It's also important to take into account what you did before the contest, many times I joined a round being very tired after a busy day and I can tell you those didn't go very well...

I am assuming you can get 4-5 hrs to sleep if that day has a contest in cf. You can take a flux with tea to your school and drink a cup of it when sleep comes. I have tried it (with 0 hrs of sleep) several times but not for a contest.

There is another good way you can try is to sleep more than 9 hrs on the previous day of cf contest day and sleep fewer hrs as you need after the contest.

Believe me, I am not an expert in cp but an expert at "how to not get sleep and concentrate on work" in emergency cases :)

As a UTC+9 student,

  • Take a nap before the round
  • Sleep before systest, and do the upsolving next morning
  • Eat or drink something after the round, and at least go to bed and take a rest (then you'll fall asleep)
  • Hope unusual earlier timeslot
  • 100% avoid of dozing off is impossible (especially joining night CF Rounds), so well-preparation for your class is necessary.
  • At last, not to waste your classes like me!

    Take a nap before the round

    this would almost definitely not work if you're concerned that your solution might get FST. (by concerned here I really mean scared af for several reasons such as when your solution passed by only a small margin away from TL)

    I usually don’t wait for systest so it’ll be fine for me about the systest part

    I do think I should try napping before the round, ty for advice

    The comment above yours says about drinking tea, I do think it will help

    All in all I’ve gotten quite a few good advices, ty guys!

I may try to stay up a bit late the day before contest, so I will feel a little tired before the contest, so I can take a one-hour nap and have a good status at contest.

If you want to ensure your sleep, the most important thing is to forget the round as soon as it ends. Then you will be able to sleep for 6-7 hours. Check the systest result and upsolve the problems after you wake up. (Well, this is difficult to me because I always want to insist on solving the problems until I solve it. But some of my friends just do so and I think it is theoretically much useful)
