Re: computer-go: Go4++ IGS ranking



A problem for computers on IGS is that most people challenge stronger
players, not weaker, and they often take fewer handicaps than the
ranks would indicate.  So the program has some upsets with weaker players
at the wrong handicap, which drags down the handicap, but no corresponding
upsets with stronger players.  If the programs challenged players 1 or 2 ranks
stronger it would make a  big difference I think.

Following on from the recent discussions about rankings on IGS
I decided to analise my most recent 115 games played there.
The discussions about rank have often been in relation to
the first game so what I have done is to only include one game
from each opponent - the one played earliest (which still may
not be their first ever game, because they might have played
before the 115 I have analysed). I have only monitored results
in the range 14k* to 18k*. I have ingored any games lost on
time by either side because it is too difficult to work out
if this was because of escaping or network problems or problems with
my IGS connection code etc. I have also assumed komi is 5.5 for
all games even if it was played with komi at 0.5 which IGS
sometimes sets (I know this is a bit dodgey but at this level
I don't beleive that so many players are modifying their play
according to such accurate counting). Ther results are as folows:

14k* no games played :-(
15k*  2/4  = 50%
16k*  4/5  = 80%
17k* 11/14 = 79%
18k*  7/9  = 77%

Here are the results in more detail:
