Rayon (rn-3.9) is the strongest open source go AI

[Shoreline]

Leela just hit 9d on KGS. Is that stronger or weaker?

Short answer: it's stronger
But why compare between non-open source and open one?

Because I misread the reference to it being free as it being open.

I think comparing strength between leela and RN3.9 is fine. But the result does not change my title here because leela is not open source go program.

Hi,

I've tried looking for any information on the Rayon bot. Do you have a web link to the source code or it's homepage.

Thanks

Home seems to be here:

https://github.com/koban6/Ray

Edit: Ahh it's the zakki branch https://github.com/zakki/Ray, not koban6 branch, as pointed out later in this thread.

KGS 9 dan is only equivalent of DGS 6 dan.

Doesn't it because DGS maximum is 6d? Are all DGS 6 dan users get 9 dan in KGS (if they play on both server)? If not, what's the lowest KGS rank of 6 dan DGF user?

I just saw DGS 7d today. The maximum dan at DGS is not 6 dan.

Yes, there are nine 7d's (currently one of them is active) on DGS.

DGS has a nice way to display all top players and their ranks in real life/on other servers:

It seems that 6d is the maximum rank one can claim without playing a game on DGS.

How to run this bot? I want to test it out.

Why not post the home page here? It is open source right? I'm not so familiar with the dragon server and was lost in finding any info.

Thanks. I'll take a look.

Thanks for the link, I see one 6 dan DGS user is 7d on KGS.

It seems that Rayon runs on cgos with 4 cpu's but no gpu (rn.3.9-4c until 2/19 and rn.3.10-4c since then). Do you have any idea how much impact the gpu makes?

[zakki]

Rn.3.3.1-4c0g doesn't use gpu. http://www.yss-aya.com/cgos/19x19/cross ... -4c0g.html
Other Rn.xx-4c uses i7-2600K (or 6700K) + GTX980ti

I think GPU impact on RN3.9 is quite large. Rayon seems to be able to take advantage of GPU resource fully in my setting.

In DGS turn based go server set up, GPU may not matter because you can make it longer thinking time, say instead of 10 secondes per move, you can strengthen the bot by making 20 seconds or even 1 minute per move. However, in KGS or CGOS, I suppose the rule is much tighter, because the bot may lose by time out.

I took back my words. the difference with GPU is not just "large", it is dramatic. I was using same playout number in CPU only mode
for a couple games, the RN3.9 (CPU only) is quite weak, no where near the 1 GPU version I set up at DGS.
It could be that CGOS was set up by author with 4 CPU who knows how to optimize the parameters. For me with no real understanding of the software, the difference is dramatic.

Were you able to get this compiled for windows? I used MWIN2 with gcc 6.3.0 and CNTK beta 11 but I get tons of segmentation faults. It does rarely run, although even when it does run it just exists to desktop. No interactive gtp prompt like I expected.

I tried using the CNTK "cpu only" version since I don't have an NVidia GPU. Just to see if it'd work.

When I compile this it says it is version 8.0.1, the same as a compile from one year ago.
