A horror mood, indeed.

Colin is a motivational speaker orz

I have deep rooted fear of string problems. My fear is more than the lack of knowledge. Irrational fear as you say. But you motivate me man. You are touching other people life in positive way. Keep doing such videos.

The main reason for not growing rating wise is not learning enough from past contests. The sooner you realise this the faster you gain ratings.

Hey, the audio quality is a lot better now.

Hi, thank you for sharing this, I've been sad because of poor performance in recent contests & this video really helped me figure out what I was doing wrong.

This video has a whole different vibe... Motivated , Loved it :)

Thanks for the advice man, I'll try my best to follow it

Thanks for such amazing content!

It was weird listening colin clear, I'm used to his previous voice which was bit unique in that microphone.

if he will lower the lower freq. it will be great. It distort little in 2x. just a suggestion

Wow, this part about removing failed contests made huge impact one me. I never thought, how do they change rating in long run, but now my eyes opened, and I fully understand, that its all about my skill. Becoming better at contest will "instantly" compensate all of rating loss.

Thanks a lot for this. Really helped me.

@Colin, how do you suggest to watch any video series on any programming topics such as yours. Should we solve the problem ahead of time and then listen to your solution videos? I guess my main question is, how can a person learn from by solving few problems and for remaining, read the solutions because one can't solve all problems with so many websites with so many problems on each of them. Or how can I critically listen to any video on programming topics?

Thank You, Bro, I wish I would be able to beat you someday : )

One small question, how did you get that "performance" column under your "contests" page? (The column beside the "rating change" column)

I actually never want to miss contests even though I can solve 1-2 problems in Div2 (I have streaks of 7-8 contests back to back). But on some days I can't join on time(maybe 1hr late because of classes) so should I still participate and submit(which will obviously result in -ve delta) or I should not spoil the problems and virtually participation instead?

@ColinGalen

3 жыл бұрын

I probably should have mentioned this in the video. If you're forced to miss some part of the contest, then it's usually okay to virtual it later, as long as you're able to take it as seriously as a contest. (My argument about rating representing true skill doesn't apply here, because if you're forced to miss part of a contest, you have an inherent disadvantage vs. other people)

How does the performance column work? What does it indicate?

Colin, what if I can't solve past 1-2 problems in Educational rounds? What should I do in that case? Should I stop trying or start practicing on the problems list (easy -> hard)?

Hello galen.Will you make a video of you doing cotext.

How do you learn from a problem ( or editorial / solution ) where you already knew every trick / knowledge needed to solve it but you still couldn't solve it?

Hey colin can you tell if I should upsolve and practice topics of the current contest and then go take part in next contest or should i take part in every contest?

@ColinGalen

I would say that doing every contest can't hurt, as it can give you a lot of information about where you're lacking in

When i watch your videos i feel like every thing is easy and go to CF solve problems 😂 , i need your advice how to practice on topics and how can i prepare for icpc your topics stream really help me so much thanx for your hard work .

Hey,Colin i did 3 contests and i didn't able to solve any question. i don't know what's wrong with me. what should i do right now?

@ColinGalen

3 жыл бұрын

Earlier problems are often heavily based on math and reasoning. I would guess that a strategy would be to spend a lot of time just thinking about problems and pursuing random ideas, even the stupidest ones. If you can rule out all your wrong ideas, then eventually you'll be able to settle for the right ones. Solving other things like math problems may also help with that sort of reasoning.

For me, the majority of the cf contests are in the middle of the day in the middle of the week. Are you guys always taking off?

How did you add performance column in your contest page?

Hi the problem I generally face during div2 rounds is that I get stuck on either B/C and then I just don't feel like skipping a lower problem for a higher problem like D and then I end up not doing either of the problem :(

hey @Colin if you are using java as your cp language,could u please share your template thanks!!

Man, maybe it’s just me, but I feel like participating in contests as a total beginner feels sorta hopeless. You get tunnel-visioned for a single convoluted approach and end up not solving anything because you spent all your time trying to fix trivial errors like runtime exceeding. Also doesn’t help that they don’t even show you the pre test cases that your program failed on.

Oddly, I miss the old microphone :(

My rating graph is 180degree and I'm stuck with ratings like -10 +7 -2 -9+10.

How can we improve our speed 😅

Why you don't do contests anymore?

In your "optimistic rating change" calculations, you ignored contests on which you would have lost rating, not just the ones on which you did lose rating, right (the two are different because a mild +delta in real life could be a -delta optimistically since you have a higher optimistic rating)? So pretty much you were looking at the subset of contests that maximizes your total current rating?

@ColinGalen

3 жыл бұрын

Yes, I calculated each rating change based on the current optimistic rating and made decisions based on that.

Participating in these contests is the reason why people have imposter syndrome. They don't learn real world technologies, instead they learn to participate in contests, and when they get a job, they realize they don't know anything about technologies and they feel stupid.

I recently posted in codeforces about getting upset about being bad and how I should kill myself. Your video has helped me a lot man. Thank... really thanks

I guess you have atleast 70 percent audience from INDIA

Biro please teach comptetive programming from basic
