Life In 19x19

About the ko - I don't understand exactly what ko is being referred to. It looks like all the kos on the board involve groups that are dead (and so there's no need to play them - and the side that owns the territory doesn't want to play them). What am I missing?

I recently noticed that Electron-based GUIs such as Sabaki, LizGoban, and my own Ogatak have lower KataGo performance on my machine if they are configured to use hardware acceleration. While this makes some sense (because it could mean the GUI and the engine are fighting for the GPU) I am certain ...

v1.5.1 adds automatic font size adjustments for the board, which was one of the most obvious missing features.

Ogatak does this rather easily (well, as long as you stick within "normal" komi range of 0-7.5) you can just left-click or right-click the komi on the fly.

I'm in the process of writing a simple game database app for my own purposes. It can search by things like player names, event, date, but not position. You can see what it looks like at:

It's currently good enough for me, but not really usable by the masses in ...

Hi, this seems interesting, thanks. Audio is OK for me.

Alright, I added the ability to edit root properties such as player names, so afaik it's now a fully functioning SGF editor. I didn't really intend to make a fully functioning SGF editor, it just happened by accident, and I suppose if that's all one wants, there's not much to recommend it over ...

Done some more work on it and one can now edit board positions and basic markup, among some other improvements.

Since I made the original post, I've made a series of incremental improvements, to the point where I'm actually fairly happy with it now. It handles most weird SGF stuff, it handles GIB and NGF, it draws the game tree, it can draw marks (like triangles etc) and labels and comments (though not edit ...

The graph immediately to the right of the board shows the winrate and score estimates (for positions the engine has actually run on). You can switch between which one is prominently displayed using the Display --> Graph menu items.

You can generate a graph for the entire game by going to the start ...

By the way, does Ogatak use KataGo's analytics engine? If so, what is the difference between a GTP engine and an analytics engine?
Yes, it does. I'd say it's easier for the GUI developer to use. For one thing, it's stateless, in the sense that, when making a new query to KataGo, the GUI supplies ...

Hello
I got an error when I set KataGo 1.9.0. Do I always have to use KataGo 1.9.1?

KataGo 1.9.0 had a serious bug which can cause crashes, so yes.


Also, does the configuration file need to be analysis_example.cfg? Is default_gtp.cfg not possible?

Uh, I don't know to be honest. I personally ...

Hello all -

I've lately been attempting to write a Lizzie-ish GUI (for KataGo only) and it's reached the point where I'm no longer entirely ashamed of it, so if anyone wants to try it out, see:

Comments welcome.
