it is more of a stack actually
Why? , it says in queue
Because, first submission should be evaluated first — "First In First Out". That's a queue.
CF randomly evaluates the first few submissions without strictly following the order.
I think it is because if you are solving mashup you are not in the same queue with others.(but it is just guess)
Idk ;)
Maybe Mike was playing computer game on judgers :)
But I think many useless submissions from bots cause it
In fact, Mike has already banned a lot of bots.
UPD: Well, still some bots left...
Yes, it's very good, but not all of them are banned. Some bots, for example vjudge bots, were useful because I think a lot of people (including me) use vjudge for every virtual judge on the site (this is just my opinion).
UPD: WHY THERE ARE BOTS? WHO CAN WANT THIS?
idk why but I found some new bots now for real: cokwqwjsc21191 tembqvdldx60894 rnhyhd585
They are obvious because of the UUID in their codes.
I don't want to update my old post, becuase I don't want necroposting...

UPD:i ll update it when i see new
UPD2: MikeMirzayanov please ban them.
I think you must ask codeforces permission for banning bots.
Submitting 20 times in 10 days doesn't seem to put a lot of pressure on the evaluate queue.
but if 10 or more bots do it same time then..
Even with 100 same bots, there are only 0.002314 submissions per second.
oke
I didn't say it effect judging queue a lot...
I just want to say there's no bot, but find new bots then...
But the bots before is really crazy, 3~4 submission per minutes.
dequeforces
-_-
sao nộp mà máy không chấm vậy mọi người có bị như vậy ko vậy
olan seylerdi, nevermind
oke
It's going to be Queueforces.
More like a randomized queue
