Discussion

Mschribr - It would be great if we can add a graph of the Historical Bot Rankings chart. How do I add a graph? March 16, 2012 04:45

yoyoma - You would have to make one, save the image on the internet somewhere, and link to it from here.

GoRoGoRo - Missed the game info for Zen19S. In July Zen19S scored second place in both these 21x21 tournaments: http://www.gokgs.com/tournInfo.jsp?id=600 http://www.gokgs.com/tournInfo.jsp?id=601 -- Rainer Rosenthal, July 22, 2011

What are the time limits used in these games? -- Mark Schreiber, June 12, 2011

yoyoma - Most of the highest rated bots use fast time settings, Zen19D 5d uses 9x:15s overtimes. Typically they lose about 1 stone when using more normal times such as 20+5x:30.

Is 9x15s close to 20+5x:30? Is there a standard time used in amateur tournaments? mschribr 14/6/2011 21:52

yoyoma - Eh? Not close. 9x:15s is considered blitz or almost blitz. 20+5x:30 is close to what KGS calls "medium". Many small tournament would typically be a little longer, maybe 45+5x:30, maybe longer for a serious tournament. But for the purpose of this page, 20+5x:30 is about as slow as you will typically get on KGS.

Does KGS give a rating for each different time limit? Are the fastest games on KGS typically 9x:15s? mschribr 15/6/2011 12:26

yoyoma - Only one rating per account. That's why many bot owners make different accounts for different time limits. Many people play with :10s byoyomi. The fastest KGS allows for rated is 1:47 + :06s byoyomi.

Do we know which programs use slower time limits? Can we add the information on slower time limits to this programs in the table? mschribr 17/6/2011 19:26

Thanks for adding the table “Current KGS Bot Ratings”. Maybe we should split the top table, “Historical KGS Ratings of a few bots”, into 2 tables. 1 table for computers that play at 20+5x:30 or slower. A 2nd table for computers that play faster than 20+5x:30. mschribr 1/7/2011 12:46

notes

^[1] For this table to get a rating R, the bot must have a solid rating of R or better for 20 rated games in a row. If the bot gets a ?-mark the count is reset. As of 2008-7, CS and mogo have both been 1d for a few games, but couldn't hold it. Leela has been 2k for a few games.

In 2011-04, bonobot aka CrazyStone reached solid 5d and held it for a short time. It quit playing games and it's rating drifted down to 4d. The same bot came back on the CrazyStone account and is holding a 4d rating as of 2011-05.
