Re: [Computer-go] Mailing list working?

It has achieved that goal, but the further goal of getting AIs to explain and 
teach is still out there.

I used Firefox on mac/yosemite and it worked fine.

Thanks for the tip. I agree and I have no intention to misbehave.

Thank you Josef for that script.

Point taken, I would not want to spoil the kgs experience for users.
I think a few hundred a day would be easily handled, after all I’ve heard it 
said
that approx 25k games a day are played on it. Clearly if I tried to download
all games from say 2010 onward in one go that would be horrendous and
most uncivilised of me.

[Computer-go] Scraping lower-ranked games from kgs

[Arthur Cater]

Hello,
I would be interested for research purposes in getting lots of game sgfs of
lower-ranked players, to contrast with the high dan and pro games that 
get put into collections. Even kyu games. I was thinking of getting them
from kgs archives.

I wonder if anyone already has a script that could (or could be easily adapted 
to) do this? And would they share?

Thanks,

Arthur

Re: [computer-go] rotate board

[Arthur Cater]

With 8 hashes per position, the chance of two different boards  
producing a different set of hashes but
the same canonical hash is greater than 1/2^64, because there will be  
a bias in the choice of canonical

hashes - toward numerically lower numbers, for instance.

I think.

The idea is that any of the board the can be transformed by mirror

board and the canonical hash represents the class of 8 boards  
produced by mirror/rot.


It is true: Another board in the class - same set of 8 hashes -  
same canonical hash.
It is almost certain (prob = 1/2^64 per check): A different board - 
 a different set

of 8 hashes - different canonical hash.
