recognizing games

It is quite easy to avoid duplicates using a signature.
For full games, where one only wants to defend against
reflection/rotation, use the minimum of the eight md5sums
of the sequences of moves obtained by rotating and/or reflecting
the board. For possibly truncated games, use the same idea with
as basis a Dyer-type signature on six or eight moves.
Software like sgfinfo computes such signatures.

Best resources to get started with UCT?

Hey everyone,

the playouts of my bot are finally (somewhat) fast enough to start implementing UCT and I wonder what the best resources are. There's the Senseis page as well as the original paper, but I wonder if there are other papers out there that are newer and maybe can give me an overview on what has happened in the mean time.

Cheers,

Urban

CGOS back online

CGOS is back on boardspace.net and running.  Please feel free to try
and connect like you use to and let me know. I'll be monitoring it.
It's just as it was when it was taken down after Mr. Daileys passing.

I'm grateful for  Dave Dyer for hosting it in the past, and for
keeping a clean copy of the system as Don originally wrote it.

Originally I wanted to host it myself but the code is rather delicate
and I never could get it running properly.  I'll still be maintaining
it and keep track of it's ups and downs but for all intent and
purposes it "just worked"  back then so that's why I asked to use
boardspace again to get things rolling again.

Thank you for your understanding,
-Josh

What's a good playout speed?

Hey everyone,

I'm currently in the early stages of writing my own Go engine and right now I'm trying to make my playouts reasonably fast. I've come a long way in the past few days. Probably not because the payouts are really fast right now, but because they were just so slow before. :) Right now I'm at ~2000pps on 9x9 and ~1000pps on 19x19. This is for playouts with simple ko and suicide checks and no concurrency. Now I wonder if this is fast enough to even start thinking about implementing a UCT/MCTS player and also if there's something I'm missing with the playouts, e.g. is the suicide check necessary?

Thanks for your input!

Urban

CGOS anchor engines

Anyone have a list of stable, freely downloadable Go engines that I
could use as anchors?
Name/download/ELO rating would be appreciated.

Figured worse case I'd use gnugo for an anchor but would like to have
a couple of varying strength.
They can run on Windows or Linux.

Re: alternative for cgos


I think hosted is a bad idea - anyone developing a bot has a computer
and a development environment, and it may not be linux, and the extra
step of updating and installing on the host is just sand in the gears.
And of course, hosting is not free.

Congratulations to Zen!

Congratulations to Zen19S, undefeated winner of yesterday's 19x19 KGS 
bot tournament!

As usual, I hope you will report any errors or comments to me.

Nick

P.S. I am now using gmail as my mail client, and it refuses to show me 
any email which I wrote (like this one).  So I hope that at least one person 
will respond to this, and let me know that it has reached the mailing list.
