Game programs for boards more than 19x19

[Amigo]

are there any such programs?

Just for fun, a version of KataGo that should work for larger board sizes:

https://github.com/lightvector/KataGo/r ... 3.5%2Bbs29

KataGo works very well on large boards indeed: I'm 1k KGS and was crushed on 25x25 by KataGo (1000 visits IIRC) despite 13 stones of handicap... ;-(((. But I won with 17 stones

Note: KataGo is not trained at all on boards above 19x19, the selfplay is done on all board sizes between 7x7 and 19x19 (with few games on small boards and more on 19x19), and no games above, but it seems it can extrapolate well up to at least 25x25 and apparently quite well up to 29x29. If you compile it by yourself, it can play up to 37x37 (but unsure if it still extrapolates well or if the level of play is drastically weaker).

[And]

Friday9i I will be very grateful if you compile the version up 37x37! I will do any tests for you!
who can it, make a version up to 37x37!!!
Please

which network did you use? and what GUI?

The new version of q5go 1.1 works great on 29x29!

Unfortunately I did not manage to compile it when I tried a few months ago... So, no, I cannot help, sorry

[And]

Friday9i Have you tried compiling this version?

Well, maybe. SGF has long supported large board sizes, so any full-featured GUI that simply conforms to the spec may have no problem opening big board game records. It's GTP (the basically universally used bot<->GUI protocol) that is the issue and that if you conform to the spec, only goes up to 25x25.

[And]

Friday9i Do you have plans to make a network trained on boards up to 29x29? maybe she will play in a completely different way? and if there is such a network, maybe lightvector will release a KataGo up to 37x37?

[And]

who wants to save q5go (up to 29x29) game and then view sgf without errors - in sgf in a text editor, you need to replace "{", "|", "}" with "A", "B", "C". The resulting sgf opens without errors in MultiGo, CGoban, and Sabaki!
with AkelPad it took me less than a minute http://akelpad.sourceforge.net/en/index.php

It would very probably take a lot of time and many GPUs: current KataGo's net trained by lightvector is extremely strong up to 19x19 (significantly stronger than LZ now) and apparently very strong up to 25x25 and probably up to 29x29 or more: it's very probable that taking the same GPU power to train a net on sizes from 7x7 to 29x29 than the time he used from 7x7 to 19x19 would lead to a net better on large board sizes (and unclear for smaller sizes, probably weaker due to the much longer time to generate selfplay). But it's months of training with many GPUs, so clearly not easily feasible ;-(.
The best hope is if there is a collaborative project using KataGo and training on sizes from small boards to (very) large boards, and if possible on rectangular boards too . We'll see!

I don’t know how good the last nets are on big boards. there is nothing to compare. you play stronger than me. Your opinion about the game of these networks on 25x25 - 29x29 is very interesting!
