How do you define “beating GnuGo”? My bot is a standard MCTS bot that is considerably stronger on 9x9 than it is on 19x19 and it has no problem beating GnuGo on 9x9 but is much weaker than GnuGo on 19x19. Which division should I apply for? Urban On Sat, Oct 1, 2016 at 4:26 PM, Nick Wedd wrote:

[Computer-go] Weak bots to run on CGOS

Hey everyone, I'm currently running Brown (random bot) and GnuGo on CGOS 13x13. Mainly to get a feel for the strength of my own bot. And my bot is really bad. ;) So bad that it looses all games against GnuGo, but wins all games against Brown. So, the rating is a bit useless I assume as there are n

[Computer-go] Observing a game in GoGui that's running on KGS/CGOS

Hey everyone, I'd like to display some statistics from my bot as an overlay for the current board. Using live graphics on GoGui is probably the easiest way to do it. I just need to run the bot in GoGui and emit the proper commands on stderr. Now my question is if there's a way to do that for game

[Computer-go] Chinese vs Tromp-Taylor rules

Hey everyone, I'm still at the early stages of development of my bot . Right now it only supports Tromp-Taylor rules as this is what CGOS uses (well, almost). This is a bit problematic, as for one my bot and GnuGo seldomly agree on a score (even when running Gnu

Re: [Computer-go] cgos.computergo.org down?

Yes, it did move back there. Unfortunately even when your bots can connect there they won't play any games. The 13x13 used to run until the beginning of the month, but sadly that one has stopped working, too. I wonder if there's anything we as the community can do to help? Urban On Sun, Mar 1, 20

Re: [Computer-go] Best resources to get started with UCT?

Hey there, thanks, I'll check out Petr's thesis. That seems like a good overview of the whole topic. And as far as what to implement. Yes, UCT can only be a first step, but as I do this in my free time I have to do it is small chunks. So first UCT, then maybe RAVE, Mogo style patterns, etc. Urban

[Computer-go] Best resources to get started with UCT?

Hey everyone, the playouts of my bot are finally (somewhat) fast enough to start implementing UCT and I wonder what the best resources are. There's the Senseis page as well as the original paper, but I wonder if there are other papers out there that are newer and mayb

BTW, which GTP commands are required for a bot to play on CGOS? The basic commands are probably not quite enough, right? At least time_left and time_settings should be implemented if I remember it correctly. Urban On Wed, Jan 14, 2015 at 10:43 AM, Urban Hafner wrote: > Great! Thank you Jos
