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: [ext] http://www.gokgs.com/tournInfo.jsp?id=600 [ext] 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

[172] - It's clear that the intention of the first table is to record the highest rank ever achieved, but is this the intention of the second table, as well? If so, we should re-label it: "current ranking" is unambiguous.

mschribr - Are Zen19qq and Zen19bs versions of Zen? Should we add Zen19qq and Zen19bs to the charts? Zen19qq is in the top 100 kgs players. Zen19bs was a kgs 6 dan since August 2011. August 25, 2013

mschribr - I see Zen19qq and Zen19bs are not computers. September 17, 2013

hogweed: Note that you can see a robot icon for computer players on KGS, if it is not there, the account is not connecting via KGS-GTP protocol.
mschribr: Where on KGS are these robot icons for computer players? September 21, 2013
hogweed: Do you actually log into KGS? If so, you should see a monitor icon beside the name of a robot player. See the KGS Help pages for more details.
mschribr: I see a robot icon when I am looking at the game board or challenge a player.

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.
