Re: Computer-go Digest, Vol 64, Issue 18

Dear Alexis,

Actually, there are quite a number of groups that would be interested.
I know of Ingo Althofer, Jena University, 
Ulf Lorenz, Siegen,
Mark Winands, Maastricht,
and our own group in Leiden (lead by Jaap van den Herik, we moved from Tilburg to Leiden about a year ago).
If you are self-funded, that would certainly help, but we also regularly have open PhD positions, of which some are definitely related to Go.  
With one of my current PhD students we are working very hard on parallelizing MCTS.
We have a sizable games group with PhD’s, postdocs, and MSc students.

Actually, in July we are organizing the Computer Olympiad, and the Advances in Computer Games Conference. You might want to check these out.


Kind regards,

Hi Leandro,

Thanks a lot for your answer!

I'm going to look at the links you gave me.

Best regards,
Alexis Audran-Reiss

Hi, Alexis,

You may also want to take a look at Alberta University (Martin Muller) or
Université Paris-Dauphine (Tristan Cazenave). Overall, you could take a
look on some volumes of the *IEEE Transactions on Computational
Intelligence and AI in Games *(
http://ieeexplore.ieee.org/xpl/RecentIssue.jsp?punumber=4804728) and see
who publishes on the topic. You can also check survey papers about Go or
Monte Carlo Tree Search, etc. I would imagine that any researcher that
works with games or board games could be interested in advising about
Computer Go.

I myself have been using Go a lot during my PhD (
http://teamcore.usc.edu/people/sorianom/). So you may also be able to use
Go as a domain to research about some other topic (in my case, voting and
teams, for example).

Best,
Leandro

Hi Alexis.

Tilburg University in the Netherlands is doing a fair bit of research of
computer go, and they occasionally have PhD positions on this.

Cheers

Hello all,

I have been in the loop for two months now and I find it really
interesting.
I wonder if it's possible to accomplish a PhD in this topic? It would be
an amazing subject, but I don't if some universities do that.

It would perfectly match my love for go game and my interest in
mathematics & computer science. (I'm graduated from a french university,
specialized in probability (& finance but it's useless for our
conversation)).

Hi,

I was curious if a board shown in a different way would give new
insights. My first experiment can be seen here:
http://vps001.vanheusden.com/~folkert/go-hon45_09.mpg What I did is
update a board each move and then for each board draw it next to the
previous board. So if you put a stone on a1, then you will eventually
see a line from it. I did not remove dead stones here. Black is green,
white is red.

michi-c a recoding in C of Petr Baudis's michi

Hello !

End of March, Petr Baudis released his "Minimalist Pachi" called michi 
(thread Michi - "15x15 ~6k KGS in 540 lines of Python code"). I found 
the goals of his project (see the README at 
https://github.com/pasky/michi) very attractive.

So, I decided to recode michi in C following Petr's suggestion
  "One of the things I would hope to inspire is rewrite of the same 
algorithm in different, faster programming languages".

I tried to keep C code very simple and translated michi python in a 
straightforward manner when this was possible (almost everywhere).

The result is available at https://github.com/db3108/michi-c. (after 
some discussion by email with Petr, we decided that it would be better 
to make separate projects on GitHub)

Obviously the code got fatter (1300 executable lines of C instead of 540 
of python). But it also got faster, almost a 10x acceleration, even if 
it is yet single threaded.

Here is an extract of the results obtained against gnugo. More results 
can be found in the perfs.txt attached file.

michi vs gnugo-3.7.10 level 10 (400 games 13x13)
------------------------------------------------
          nsimulations/move          1400      4000     12000
python   winrate (%)                36.5
  code    time per game (sec)       430.6
    C     winrate (%)                37.8      66.5       80.8
  code    time per game (sec)        44.2     123.4      340.7

michi vs gnugo-3.8 level 10 (400 games 13x13)
---------------------------------------------
          nsimulations/move          1400      4000     12000
python   winrate (%)                41.8
  code    time per game (sec)       419.5
    C     winrate (%)                38.8      66.5
  code    time per game (sec)        44.9     124.6

Uncertainty on winrates is between 2 and 2.4 %.

There is still a lot of room for improvements. As the speed of the 
program is concerned, the 2 main ones are :
- parallelization
- fast board implementation with incremental update of blocks and liberties,

I have plans to continue to work on it with the priority of implementing 
the fast board. Adapting existing and well tested code that I already 
have, this should not take too long, I hope.

Meanwhile, if someone would like to try his hands on parallelization, 
his efforts would be much apreciated. Some kind of coordination should 
certainly be necessary, as I used for simplicity some constructs that 
could prevent easy parallelization. But I hope this could be manageable.

For the above modifications we must relax the objective of brevity. So 
this will be the right time to include some functionalities that will 
increase the usability of the program (time management, variable 
parameters modifiable by gtp commands for CLOP tuning, variable 
boardsize, "intelligent" early passing, etc.)

I believe that these new developments should not be detrimental to the 
clarity and the brevity of the original michi and I would like to let 
michi-c unchanged (except for bug corrections and/or modifications to 
make it clearer and shorter).
Therefore, I have setup another project for the new developments at   
https://github.com/db3108/michi-c2

Any thoughts ?

PS. If someone can understand and help to correct the spurious message 
got from gogui-regress when running make test, I would be very grateful. ;-)

topological go & gtp

hi, i am writing a go program in java that will let you play on a torus like little golem and on a board with holes in it.

i need to be able to somehow play with someone over the net.

so i guess i need a version of gtp in java.

i think there is one in orego and a few other places.

does anyone have any recommendations?

thanks
