Re: [computer-go] Just for fun
I've written a small program to estimate the rank of players based on
their 9x9 game records in the kgs archive. Here's a few results based
on games with < 2 stones hcp against players without '?'.
Handle Games Rank
-----------------------------
gnugo3pt6 108 9.35k
go81 241 17.7k
viking4 90 17.9k
viking5 431 18.3k
botnoid 115 19.3k
tlsbottest 38 19.9k
dumbbot 229 27.7k
nio 18 29.9k
Remember that these are only estimates. It does not account for undos
or incorrect scoring. I repeat once again that these are ESTIMATES. ;)
