Let's hold an ARC Lockout Tournament. The idea is inspired by ecnerwala's Lockout tournaments and kenkoooo's ABC tournaments. This is not an official tournament, so there will be no prize; the winner gets the honor as the champion of the lockout tournament.
The rule is basically the same as ecnerwala's.
- I use the actual points in the contest (like 300-400-500-600-700-800) to judge the winner.
- Only the user with the earlier AC time gets the assigned score (tie-break by submission ID)
- The time penalty doesn't matter.
- In case of tie, the winner is the first one who reached that score (again the tie penalty doesn't matter).
- In case both participants skip the round, the winner is the one with the higher rating at that time.
I don't want to mess up the results of rated participants with this format, so you need to be a red or above on AtCoder. If you want to participate, please reply this thread with your AtCoder handle by November 21st, 0:00, JST (that is 21 hours before the start of ARC 108). After that, the tournament bracket will be made in the 18452736 manner by ratings.
The first round is ARC 108, the second round is ARC 109, and so on.
UPD: I don't want to decrease writers because of this; if a match involves a writer or a tester, the result of the match is determined by the next ARC.
UPD: Thank you for the registration! Now the registration closed. Bracket You can add predictions now!
So, tomorrow is the match between Anadi and Golovanov399.
Um_nik (not red on AtCoder but I think it's fine)
Not red but I'd love to use this as motivation to wake up early and maybe get red :(
If you are an orange, of course, you are welcomed to participate in ARCs in a standard way!
Once you reach red, ARCs will be unrated for you and the problems maybe be a bit too standard for you, and you have less motivation to participate in them. Lockout looks like a very nice way to solve this issue. You can still play a very strategic sport.
Please stream!
The point is that it would be during real ARC, right?
Actually, this format combats cheating very well, so maybe AtCoder could sponsor some prizes?
Oh, indeed it apparently will be parallel to the ARC. Then I (not really seriously) suggest streaming with tremendous delay :)
For finals and semifinals, I suggest making ARCs unrated and streaming live.

Yo, long time ago I made a handy script so people can see which problems are locked in real-time, which might be useful for this kind of competition, but I need to submit a request to AtCoder every x second to be able to update it and I believe I shouldn't DDOS your platform during normal contests. Can you provide any kind of API?
My proudest moment in CP. It all goes downhill from there :)
Egor (just red again)
You look a lot like Eugene from Walking dead. That guy's character was also smart

Let's try, Swistakk
What happens if some contestant drops to below red after the start of the tournament?

I would love to participate, but I also don't want to solve another contest this Saturday a few hours before the TopCoder Open finals. In case I don't get a bye for the first round, would it be possible to designate me (and other TCO finalists if they so desire) as a "writer or tester" for the purposes of lockout tournament?
Yes, I will handle you as a "writer or tester". Good luck in Finals!

Fuck it I'm in.
Will there be instructions for how to do this?
Submit solutions as usual, and you can get the opponent's status in https://atcoder.jp/contests/arc108/vs?p1=Anadi&p2=Golovanov399.
It is allowed to look at opponent's submission list.
Please ask me if you need further clarifications.
In AtCoder, it's impossible to see other user's submission list during a contest.
All information you can see during a contest are standings and your submissions. (lockout page is based on standings data)
I'm not sure about seeing list of other user's submissions, never wanted to until now, but for sure we can see (-1) in standings which is almost as good. If you say that we are allowed to look at the standings does it mean that we are allowed to look at this (-1)?
Are we allowed to cooperate with opponent and write each other if we have got AC? It would be better to make notifications from ongoing match, but I don't know if it can be implemented.
Yes I meant (-1). You are allowed to do whatever usual contestants are allowed to do.
For lockout participants this is allowed too.
Are we allowed to use template and copy code from library?
Yes.

lockout page was born in AtCoder.
you can watch the first match here. https://atcoder.jp/contests/arc108/vs?p1=Anadi&p2=Golovanov399
there are reload button and auto reload button. auto reload interval:
problems will appear after the contest starts. sample
This is awesome
Can AtCoder stop being so awesome? You are making other platforms look bad.
Seems like they both missed it
I beg to differ
Interesting, because for me it shows 0:0
It started working after the end of the contest though
So it turns out that only registered users can see this during the contest
UPD:
Notification is implemented.
click "Customize".

There were some tensions about it in recent Lockout tournament so I'll ask: are we allowed to look at opponent's submission list?
Lemme answer how it'll actually work with a famous movie quote:
2nd round tomorrow?
Yes. 8 matches in parallel. Reminder:
Seems like we have "even" sum today, In case of draw first to reach that score advances?
Disregard this, I cannot read, apparently
Any explanations on how to compete? Do I just reguster for regular contest and solve some problems? Where do I see page for my match?
https://codeforces.net/blog/entry/84506?#comment-724245
You can just register and compete. You'll see the match here (enter usernames and click OK, then you'll see scores after the contest starts).
Is it one match per ARC or is it gonna be many lockout matches in parallel? In particular, should I participate tomorrow?
Okay
Okay

No really, if this is what an ordinary ARC is like, I guess they are certainly not below my level, and I should actually do them instead of AGCs. Like was problem F really for 0-2799 guys, if my opponent (who is, I'd say, far from being stupid) didn't solve it in 50 mins?
That being said, thank you guys for a nice and hard contest! I was suffering, but I kinda liked it
This time we misjudged the difficulty level of the problems and the contest was harder than usual. I'm sorry if the underestimated scores ruined someone's strategy.
Anyway, thanks for your participation, and we're looking forward to seeing you at the next match.
I don't do all the ARC but I think half of the time F is solved by ~5 participants (to be fair, usually the number of high rated participants are low in ARC), so, F being very hard is pretty much normal thing for ARC. This time I wasn't able to solve D in 20 minutes which is less usual :)
20? I spent an hour on it and still have no idea how to solve it.
Yeah, I decided to switch to E but then Golovanov399 sniped it from me :) I don't know how to solve it either.
Neither do I, I've reverse-berlekamped the samples
Thanks for the round, I've enjoyed it a lot (even though I can't really solve problems...)
ARC 110 ends 30 minutes before the start of Hacker Cup finals. Would it be possible to move it to Sunday (which has CF Global Round 12, but at least for me it's not as important as Hacker Cup finals) and/or postpone the Facebook finalists' matches until ARC 111?
I'm sorry for the second request of the same kind from me.
Since the next ARC is sponsored, we can't move it, sorry.
Please reply this if you want your match to be postponed.
postpone list: Petr
same situation
But you both are in the same match anyway
Good. Disqualify both.
same situation too
So, there will be two matches tomorrow. Reminder:
So sad for being able to participate this match :(
and lost :)
Hi, is it true that there will be an ABC tomorrow and therefore the next lockout round is no earlier than in a week?
thanks for uploading screencasts they're very cool !!
Reminder: Tomorrow we have an ARC and the matches will be
By the way, we have a sponsored contest with ARC quality and difficulty next week, but it doesn't have ARC in the name. Should we hold an "ARC" lockout next week? If you have a particular opinion about this, please tell me. (Now I'm planning to hold a match next week.)
Thanks for the round!
I'm happy to participate next week.
rng_58 please update the result of the last match.
Reminder: today we have a match Petr VS gamegame.
Reminder; tomorrow we have the Final Round: Golovanov399 vs Petr, and the Bronze Match: Merkurev vs gamegame.
Good game
gg!
Who won?
Petr 1700 : 800 Golovanov399
Merkurev 700 : 1800 gamegame
Congratulations to all and specially to Petr for winning . :) .
