LizGoban 0.6.0-pre1

ladder detection & auto-continuation

• Upgrade KataGo to 1.8.0.
• Indicate inevitability of each move by its font size in suggested variations (KataGo only).
• Improve loading of nested SGFs, e.g. AlphaGo Games, so that we can read them conveniently:
  • Push the corresponding key (d, e, ...) for each branch (d, e, ... in dotted squares) to preview its sequence with comments.
  • Click one of branches (or hit Enter key in the above preview) to watch it in another trial board.
  • Click "x" mark at the right top of the board to close it and return to the main branch.
• Implement side by side comparisons of the principal variation and the actual succeeding moves, etc.
• Add stars to personal exercise book. Starred exercises will appear more often.
• Support restriction of analysis region by Alt+drag like KaTrain.
• Slightly improve Tsumego frame (boundary, analysis region).
• Insert/delete moves in the middle of the game by Ctrl+Shift+click.
• Insert a black (white) stone by b(w)+click.
• Automatically mark ladder breakers as "=" and show the continuation of the ladder by "=" key (experimental).
• Experimentally support external control of LizGoban from another program.

Incompatibilities:

• Upgrade libraries (Electron 11, etc.). So you may need to do "npm install" again.

To use it on 64bit Windows immediately

Just download the all-in-one package (LizGoban-*_win_*.zip), extract it, and double-click LizGoban *.exe. You do not need installation, configuration, additional downloads, and so on. Its file size is due to the built-in engine:

• KataGo 1.8.0 (eigen, eigenavx2, opencl) + 15 blocks network (g170e-b15c192-s1672 from KataGo 1.4.5)

You can switch KataGo versions (CPU, modern CPU, GPU) by [Preset] menu in LizGoban. The first run of the GPU version may take a long time (1 hour on a low-spec machine, for example) for its initial tuning.

To customize it on 64bit Windows

If you want to use other engines, network files, options, ...

1. Prepare engines (Leela Zero and/or KataGo) and their network files (aka. weights, models) by yourself, if necessary.
2. Download and extract the same all-in-one package as above.
3. Copy sample/config.json to the same folder as LizGoban *.exe and edit it. See README for its format.

To use it on other platforms (Mac, Linux, ...) or Windows with more flexible configuration

Download the source code and see README.md.
