Fwd: mental imagery in Go

i'm looking for people with expertise in
​art, ​
computer graphics
​,​
and/or AI software to help me make a video series about mental imagery in Go, partly with a view to expressing mental images in the form of heuristic rules that a program could use to generate and evaluate candidate moves.

any takers?

EGC2015 Events

  Hi!

  There are several Computer Go events on EGC2015.  There was a small
tournament of programs, played out on identical hardware by each,
won by Aya:

	https://www.gokgs.com/tournEntrants.jsp?sort=s&id=981

  Then, one of the games, Aya vs. Many Faces, was reviewed by Lukas
Podpera 6d:

  Right now, Hajin Lee 3p (known for her live commentaries on Youtube
as "Haylee") is playing Aya (giving 5 stones) and commenting live:

Re: Hex is solved ?

Thanks for your feedback.

Yes, it seems the strategy is only for an unrestricted first player.

I looked at the web site more carefully. It seems to present only the 
main result. The full document is not available online, only its table 
of contents:
http://jeudhex.com/?page_id=231

So it looks like 2391+ pages of hand-made proof. I don't feel like 
checking it any more ;-)

Still an impressive result if it is correct.

Re: Hex is solved ?

Being pspace complete would just make the method impracticably slow for a sufficiently large board size.

The searches in such a case will be exponential in board size and not be very interesting.

Perhaps he found a winning strategy for an unrestricted first player?
The game with the usual swap rule doesn't feel to me like it would submit to
an efficiently computable strategy.

That's most unlikely, considering that HEX is PSPACE complete...

Hex is solved ?

Hi,

I have just been told by a colleague that Edouard Rodrigues solved hex mathematically. I was very surprised
because I had never heard about it.

The web site with the proof and optimal strategy is there:
http://jeudhex.com/?page_id=17

I did not look at it in details, but it seems his method can find an optimal move on any position and any board size.

Did the computer-hex people of this list knew about it? I know there was an Hex tournament in Leiden, so I
suppose the computer Hex community might not be aware of this result. Or maybe the mathematical result is wrong?

Please circulate this information to the Hex specialists. I am curious about their opinion.

I'll take time tomorrow to study that web site a little.

Rémi

More data for DNN's?

The Maddison et al, and Clark et. al. papers,
both suffer from a lack of very high skilled games, and thus result to using (possibly blitz) games from lower ranked players on KGS. Has there been any effort to gather data from the Asian Go servers? Presumably there's even more high level games available there. I don't see any mention of this on 

Is anyone aware of other data sets available?

Also has anyone tried fooling around with training their own DNN's? I'm curious if anyone has compared the weight tying method of Clark et al, with the more brute force method of Maddison et al. where they generate additional data by applying random rotations and reflections of the games.
-Justin

Determining the final board state for finished games

Hello!
   I'm new to computer Go, it's nice to find this mailing list! I've downloaded the GoGod dataset of completed professional games, and for the games that been fully played out (no resign) I'd like to determine the final state of the board (i.e. which groups are live/dead and what territory belongs to which players). I've written a simple script which can do this for maybe 75% of the completed games, but I'm a little stuck on how to best do this when the pros end the game in less obvious states. Can anyone recommend some resources on how to best do this? Are there any publicly available scripts which already do this?
Thanks so much and nice to meet everyone!

November KGS bot tournament

I have rescheduled the November KGS bot tournament from Sunday November 15th to Sunday November 29th, to avoid a clash with another, unpublicised, bot tournament which will be taking place on or about 15th.  

Unfortunately this puts it the week immediately before the December KGS bot tournament.   This is unfortunate, but November will be a busy month for computer Go: 
and I am occupied myself on November 1st.

Nick
