Today is November 7th. And this, as you probably know, is a very special day for many ex-USSR citizens. Many years ago on this day the Great October Socialist Revolution happened. I still remember red flags and military equipment on the avenue and the feeling of common joy and holiday. But today, in 2011, we have another revolution — the Codeforces revolution of colors and titles. Hooray!
So, over the last few months our community has grown significantly. If we count the users who have participated in the rated contests over the last 9 months at least once, at the beginning of the year they were 4330, and now — 7615. This is a great step forward! Of course, this leads to a dramatic rating inflation. Most of the ELO-like ratings have the same issue. For example, only A. Karpov had Elo chess rating of more than 2700 in 1979; however, there were as much as 15 people with such rating in 1994, and in 2009 they were 33. In 2001 there were less than 10 red players on TopCoder; in 2005 they were about a hundred and now — more than 250.
A similar effect occurred on Codeforces. It is particularly striking as it is accompanied by a marked audience growth. For this reason it was decided to change the color system . In addition, the record shows that not all participants liked the military ranks. Besides, they are quite far from our intellectual and sporting spirit. Today we will disband Codeforces as a military unit and introduce sport titles. We've mostly used the titles from intellectual sport games to work out the following classification:
|2200 - 2599||red||Grandmaster||1|
|2050 - 2199||Orange||International master||1|
|1900 - 2049||Orange||Master||1|
|1700 - 1899||Violet||Candidate master||1|
|1500 - 1699||Blue||Expert||2|
|1350 - 1499||Green||Specialist||2|
|1200 - 1349||Green||Pupil||2|
|0 - 1199||Gray||Newbie||2|
In addition, the rating recalculating formula was slightly fixed to slow down the inflation. Now the sum of ratings will not be the constant, but is likely to be slightly falling. In fact, the changes are cosmetic and will be visible only on a series of contests.
I understand that for some of you it will be hard to say good bye to the favorite color, but let's look ahead with optimism — new victories will bring the lost color back color and help to win the proud title of a Grandmaster!
i think you are chicken
the second division still consists of the rating range from 0 to 1699?
Feeling sorry for the previous titles:They really suited the website's name-codeforces.
Anyways the new titles as you mentioned suites our intellectual sportive theme.
BarakBarack Obama says "Change We Need"
But I think that there is no such title as "International Grandmaster" in chess.
The abbreviation IGM for International Grandmaster can also sometimes be found, particularly in older literature.
But there is alternative. Again, from wikipedia:
The unofficial title, "Super Grandmaster", is often used by players to refer to those with a 2700+ rating to distinguish the most serious world champion contenders.
Just like there are national masters there exist national grandmasters - at least in Russia. Unlike national masters, all but one Grandmasters of USSR were also IGM, but not the other way around. I do not have similar statistics for Russia
.. For me .. I think the color leval is a little bit sharp ... maybe more evidently than it used be ..... the color should from White to Deep Red .. gradually ..? .. after all ... you can't come acroos that purple is a transition period between the Green and the Red at the first glance...
I think Specialist doesn't match with a Coder. Because, a newbie coder is nice, a pupil coder is nice too, an expert coder is awesome, but a specialist coder doesn't match... Specialist match with an Engineer...
.. +1 ... That is what I want to say ..
Anyway, in chess, players could keep their highest title, even after their ELO was dropped. Why does not Codeforces do the same?
I am more motivated now to increase my rating. I want to be candidate master.
I am probably one of the most influential members of the codeforces community from outside Russia. Some time ago the "Problem Set" feature was provided due to one of my posts. Now we get change in the titles as I requested in another.
--- End of self boasting. ----
Thank you CodeForces for all the effort!. Officially there is no other system around the world that takes such a great care to provide its users with exactly what they want.
Only Petr & tourist are International Grandmaster
The gray color and Newbie title is for 0-1199. What color and title will negative-rated coders like worse get?
Pink, antiNewbie, div3.
WTF! negative rating?!!!
How did the old military ranks look like ?
MikeMirzayanov I just noticed that 2600+ is "Red" and 2200-2599 is "red" and there isn't 3000+ Legendary grandmaster title
This post is 9 years old dude. Might have changed a lot now
i thought after looking my message he will update the current one, or add new post
There is the second post regarding your concern, The Second Revolution of Colors and Titles
oh thanks!! i didn't find this one after looking so i decided above conclusion.
I really like the military ranks.
