Suggestion about rooms
By shevlopmes, history, 17 months ago, In English

Hi Codeforces!

Today I took part in CF Round 882. As you can see, I was the only purple participant in my room, and, as a result, the only one to solve D.

Thus I was not able to see (and, maybe, hack) others' solutions of D. I think this contradicts the idea of hacking on Codeforces, so I suggest making room distribution dependable on participants' ratings. This will allow to see and hack not only submissions on easy problems

How is the room distribution logic right now is ? Is it random or based on the time of registration ?

    I suppose it definitely isn't based on the time of registration, otherwise somebody can make a fake account, register at the same time, get to the same room and hack submissions from a fake account thus make something rooms were created to prevent. I don't know whether it's fully random or not.

Well imagine having a room full of candidate masters and experts who would hack the specialists/pupils right now ? I think having high rated contestants with lower is essential for hacking. I am not saying that the current solution is perfect I don't know how it works (I am guessing randomly, but I don't think your solution is very valid.

    Yes, you're right, I didn't express my idea correctly. So what I suggest is somewhere between fully random and fully rating-based — it's making some rooms with like 2-3 CMs, 5-7 experts, 10-12 specialists and others, while other rooms may not have any CMs or experts. Yes, there would be some newbies or pupils whose solutions of A (and maybe B) would not be reviewed in a proper way, but they would get their FST if made wrong solution anyway, and I think reviewing and understanding solutions of difficult problems, which may be far away from yours, is a lot more fun than checking 30 similar submissions on A

Maybe creating different rooms for each problem will be better. For example, the ratings of the participants gets closer as the problem difficulty gets higher.

There are almost no hacks on codeforces nowadays anyway (which is a good thing).

Same as me in Round 877.

Only I passed D, and only 14 people passed at least one problem.
