[Computer-go] CGOS 9x9 draw rate

2018-08-09 Thread Hiroshi Yamashita

Hi,

I have checked CGOS 9x9 black winrate and draw rate.

CGOS 9x9 draw rate
http://www.yss-aya.com/cgos2018_03_07_draw_rate.png

Following table means 1800 range(both player are (1800 <= rate < 1900))
games are 397, and black winrate is 0.460.
I did not plot 1900 - 2100 because few games.

It seems black winrate tends to down for strong players.
Draw rate clearly tends to up.
Maybe over 4300, all games become draw?


CGOS from 2018/03/01 to 2018/07/31, total 130922 games

rate  games   B wins Draw W wins  Black winrate(draw is 0.5)  Draw rate
1800:   397 =(  153/   59/  185) 0.4600.149
1900: 3 =(2/1/0) 0.8330.333
2000: 1 =(0/0/1) 0.0000.000
2100: 6 =(5/0/1) 0.8330.000
2200:81 =(   34/3/   44) 0.4380.037
2300:  1259 =(  587/   77/  595) 0.4970.061
2400:  4923 =( 2346/  409/ 2168) 0.5180.083
2500:   945 =(  391/  128/  426) 0.4810.135
2600:   107 =(   43/   24/   40) 0.5140.224
2700:  1490 =(  518/  253/  719) 0.4330.170
2800:  3354 =(  970/ 1135/ 1249) 0.4580.338
2900:  1375 =(  416/  390/  569) 0.4440.284
3000:   181 =(   60/   31/   90) 0.4170.171
3100:41 =(   11/   16/   14) 0.4630.390


Following are Black first move winrate.
It seems Black tengen (5,5) is not best move anymore for players >= 2800.
Maybe one reason is Leela Zero 9x9(LZ20_128_65_p3000) only plays (4,5)
and never play (5,5).


Black first move winrate

 both player < 2800  both player >= 2800

 games   black winrate   games  black winrate
(5,5) 41929(59.2) 0.554   5072(36.7) 0.398
(4,4) 11349(16.0) 0.548   2510(18.2) 0.388

Actually it is only the updating of the webpage that does not work.  
The programs play as usual.

Ah, OK. I thought because I got the You are already logged in error
and the stats were old the server would be down.

Thanks.

The cgos 9x9 Game Archives have been updated will all the November 2007
games.   Previously the last few days were missing because they were
extracted before the month had ended.

Re: [computer-go] CGOS (9x9) hangs

2007-11-20 Thread Don Dailey
This seems to be one condition that hangs CGOS. 

At any rate, I finally restarted it.  I was actually away from any
computers for almost a week.   I notice that CGOS has been down for a
few days.Sorry about that.

It's back up and running now.
