Well, if 19x19 go is solved, how was it solved? Surely by the best network...


Isn't this a step too far? How would any net "solve" Go? I thought that the magic of nets is that they are able to play as strongly as they can despite (because?) being non-deterministic. So how will you ever be able to determine that you have solved Go if you are using a net?

I meant to imagine, assume that go 19x19 solved

I assumed that by "best network" Dragon meant the best program. I guess I should have said, "best program", myself.

What shape future programs will take, who knows? I doubt if 19x19 go will ever be solved, anyway. However, if it is, and however it may be solved, the solution can be checked with a weaker program than that solved it.

I believe that go can be resolved. and not only 19x19. modern programs learn the "network". neural network (?). If someone comes up with a program that will learn and change themselves! then I’m pretty sure that after a while she will solve go! and provide a solution and evidence :tmbup:

Finally got round to installing the new version, after genconfig it's twice as fast as before (probably I didn't tune / adjust numthreads before), nice!

Can someone please hint me - how can I play it 13x13 or 9x9 - I'm using Sabaki. Different command line and obviously different neural net files? Thx

Post subject:  Re: KataGo v1.4

Have you tried just changing the board size in sabaki?

KataGo uses one neural net for all sizes.

Kim Yoonyoung 8p (https://www.twitch.tv/kimyoonyoung) is playing a variable handicap series against KataGo running on beefy V100 hardware. She lost 2 games on 2 stones and 6.5 reverse komi and just now one on 3 stones, the "this group won't die" died after a very nice not working ladder KataGo played out to get some helper stones in sente. 2nd 3 stone starting now.

Edit: she won the 2nd on 3 stones by 8.5 points.

PS. In another 30 game test between these two nets, the score was 16-14, but I had forgotten to use -alternate, so the new net was 30 times W... :sad:

would now be made 30 times black, there would be 60 games :)

Is there anyway to play the nonzero version of katago on ogs? Thanks for the test matches!
