I wrote this article just after Edu Round #68 ended.
I participated in this contest and the past contest #573,and I was surprised to find that both of the contests contained problems that are related to games(one) another.Will this kind of problems become a trend in codeforces?
These solutions of this kind of problems may be harder to think,however,they are easier to code.Despite these issues,the problems are really interesting.What do you think about them?
I don't know if they will, but if they do, I'm doomed.
I think as long as they are ad-hoc (like in last contest) it's fine, if the problems involve actual game theory like nim game or sprague-grundy theorem I won't be able to solve them because I haven't tried to learn those ideas yet.
my timeline from past 3 days
2 days ago codeforces round #573 div1B game theory-9 wrong submissions.
yesterday facebook hackercup round 2 first Q game theory-source rejected.
today educational round #68 D game theory-6 wrong submissions.
Source rejected?
In Facebook Hackercup the judge gives it's evaluation after the contest has ended and mine was that your source is rejected, inshort WA.
Why would FHC reject a source? I thought they only checked your output for correctness and not the source
This is something even i don't know cause it happened to me last year too and this year also in qualification round and i remember that in qualification round my output was wrong but the verdict was source rejected.
It seems that we share similar experiences.
I only passed the problem in educational round #68 o(╥﹏╥)o
I think problems involving games is kinda fun but it shouldn't be part of competitive scene
Sounds great！
I’m very bad at game problems. I usually skip the round if it have number theory or game problems. I hate number theory problems, but I think game problems are good, I simply suck at it.
That’s why I skim the problems before CF, but in #573 I just participated because I thought my ratings were low enough to cover up one game problems. It turned out that it had two game problems and one number theory problems, so I got a well expected -120 rating.
Also in last FHC Round 2 I struggled to solve the easiest problem which was a game problem. I just guessed the patterns from samples and got AC. I don’t know why it works.
Are you bad all sort of ad-hoc problems or only game?
I think I’m ok with ad-hoc type problems.
