Large Goban support

[kris-computer-go]

Friday9i — Yesterday at 6:03 PM
For those interested, I compiled Windows versions of KataGo1.9.1 for Large Boards, up to sizes 37x37 and 52x52. There are OpenCL and Eigen AVX2 versions, here they are: lightvector/KataGo#454 (comment)

There is some problem in lizzieyzy with this engines. White passes after few moves and always resigns.

[yzyray]

Can you send your gtp log? Its in the config(shift-x)->other settings->log GTP to file
And the file will be produced at lizzie's folder.
Maybe its not GUI's issue current katago model is trainging at max 19 boardsize,if using at 29 boardsize(which is released in official),it can play well,but i dont think it can also handle as large as 52.

[yzyray]

oh,I've found a bug on 52 boardsize,when parseing coords like 'BA4','BA' should be '25*2+1=51' but misparsed to 25+1...it lead to place wrong stone when receving engine's response like 'play BA4',but it only effect on the last two colum's move and has nothing to do with pass...

[kris-computer-go]

I've managed to configure some 52x52 games. It only works with 20x256 model and preferably 1-3 sec/move.
There is a problem to save sgf, probably is too many moves in the game but parseing coords seems to be OK.

[kris-computer-go]

Oh, yes you're right: the last two columns are empty

[yzyray]

If you comes up saving sgf issue again,can you try to upload your logs,by select this option.(need lasted release)
Or if ctrl-c can work,you can just use ctrl-c and paste result here.

[yzyray]

Is there 'lastErrorLogs.txt'?

[kris-computer-go]

Yes. An empty one. I will try another game then.

I think i caught what's wrong here,a recursion algorithm caused lack of memory.
fix52.zip
And misparse coords is also fixed.

[kris-computer-go]

Thanks a lot. I will try tomorrow.
In my opinion Large Board games are interesting because almost every move is far from the corners and a clear fighting strategy can be observed.

[kris-computer-go]

Coords are OK now but after some 600-800 moves game is freezing

The problem seems to be with displaying board in java when the move time is very short.
Can you compile an exe version please? Also on my 4K display the graphic is better in exe version.

[yzyray]

The exe has bundled java environment to the 'jre' folder in the same path with exe,and version should be JRE15.jar will use your installed java environment ,maybe your installed java environment is a bit older,so it does not support windows scale and lead to display fuzzyment.
Maybe the short move issue relative to your java environment too,error log shows 'OutOfMemoryError'.I guess older jre can use smaller memory than jre15.
Here is the exe file:

[kris-computer-go]

Exe file works properly. Thanks for your efford.

There is still some minor bugs: option save raw branch (Ctrl + Alt + S) not working and no move number above winrate graph.
I think after some improvements LizzieYzy coult be a favourite gui for many.

I ran lizzieyzy on a 63x63 board, KataGo 15b - KataGo 15b!

Yes,there is some minor issue,will be fixed in next release.
And I also create two pr about bigboard to official Lizzie,hope it can work well.

@yzyray
Thank you very much for this wonderful program! it works with KataGo 100x100! can you add save for big boards? any option.

[yzyray]

It can be saved here:

After loaded this engine,board will be turned to 52x52

[cryptsport]

@yzyray
if I use boards larger than 52x52 (lightvector/KataGo#454 (comment)), is there any way to save the game? Could you, for example, make a record of coordinates in sgf for such dimensions? ; W [aa27]
; B [ab26]. saving on boards more than 52x52 does not work for me

[cryptsport]

Katago works on 63x63 and 100x100 https://lifein19x19.com/viewtopic.php?p=267394#p267394
saving does not work

[cryptsport]

@kris-computer-go
you can try q5go https://github.com/bernds/q5Go, there is also a pass on the first move and a quick resign. nets didn't train on such big boards.

[yzyray]

oh,you mean save the game,i think i can make it work some time later.

[yzyray]

I've uploaded a pre-release, support save games for large board,but only itself can read this kind sgf.

These issues should also be fixed.
