Ataxx

[Ferdy]

Do you have an exe compile of Sashaxxx? or any other engine that will run on acraps?

Hi,

Compiling for windows was not very complex, so: https://vanheusden.com/Sashaxxx/ <= there you can find a zip-file with exe of Sashaxxx.

Unfortunately it does not run, I am using an old 64bit processor.

Are you aware of the Ataxx-server running on the ataxx.org website? See https://www.ataxx.org/#server
Basically if your program speaks UAI (like your program does), then you can use https://github.com/flok99/waxx/blob/master/client.py to interface your program to the server. On http://server.ataxx.org/ you can see statistics.
The program requires a username and password: you can choose anything you like; a new account will automatically be created.

Yes I am aware of it. I could not run client.py because of
import fcntl
it seems like this is for unix only and I am on windows 7.

Can you give the new version a try? This version does not use fcntl.

I've also updated the exe version.

On Sashaxxx.exe, still does not run. There is cygwin_exception.

Will try the client.py later.

Thanks.

client.py is working.

[flok]

client.py is working.

Is your program Atakador? Plays very well! (ignore the neural nets because they always win)

Yes.

Tried viewing some games of ataxxzero, below is interesting, ataxxzero as black (white dots) just played a7. It does not try to gain material but seemed trying to allow its opponent to expand in the center.



FEN: 1oxx3/oxxx3/oxx4/7/7/1x3o1/x5o o 0 11

Here is Atakador's analysis, its a python engine. Just curious what it thinks.

How deep are these other engines are searching?

It is fun implementing different ideas even with this slow searcher
nullmove is ok
lmr is ok
hashtable just even (remove it for a moment)
qsearch is ok
move ordering with static board evaluation is ok
move ordering from pv is ok

Will release it once it is stable and other improvement ideas are tried.

Found a nice article on ataxx at http://www.linuxonly.nl/docs/4/0_Ataxx.html#page96
Perhaps it is better if you add this link on your website, something like programming resources section.

Looking forward! Especially is noon has succeeded in qs for ataxx yet that i know.

It has an interestijng idea about eval.

Perhaps it is better if you add this link on your website, something like programming resources section.

Will do.

Have you seen that the server-page has a live-viewer now?

Just saw it. I like the stone count info. One improvement is to highlight the last move
and show the fen. Also indicate that first player is handling black-colored pieces.

Done!

qsearch is ok

Definitely interested in what you've come up with for that - everything I've tried so far has failed.
