About this site
Impressum

A Django site.
Kombilo is a go database program. Its main purpose is to search for games in which a given pattern or position occurs. You can also search for other criteria (like time period, players, events). This program does not come with any game records, but you can import games in SGF format, so for example you can use one of the game collections which are freely available for download. The GoGod database by John Fairbairn and T Mark Hall is also an excellent choice (by the way: Kombilo is now included on the GoGoD CD).

Libkombilo in Drago 3.0

About two weeks ago, Gilles Arcas published the new version of Drago, an SGF editor with lots of features (exercise go problems, print diagrams ...). The new version includes the libkombilo library and can do pattern searches and searches for game information (players, etc.). In my opinion, Gilles succeeded in creating a very intuitive user interface for the pattern search. Drago is freeware for Windows.

Review of Kombilo on Alejo's Tenuki

A few weeks ago, Alejo put up a video review of Kombilo on his blog.

References to commentaries updated

Kombilo includes a list of references to commentaries in the English go literature (most notably to commented games in Go World). I have now updated this list to include all Go World issues up to volume 109. Altogether there are now more than 1500 references to game commentaries.

Center patterns

Currently I am working on a hashing algorithm for center patterns for libkombilo. See also this related discussion on Sensei's about this topic. Here I just want to share some observations (there are similar observations on the Sensei's page, but based on smaller database). The numbers given below are based on a database of around 50.000 high-dan games from KGS.

Trac spam

I installed the newest version of Trac which supplies methods to block spam contributions to the Wiki and the Ticket system. (I am now going with the Akismet filter. I would actually prefer a captcha solution like the one I did for the blog here, but it seems to be non-trivial to implement that within Trac, and I do not want to spend a lot of time on this.)

svn import libkombilo

I just imported the first version of the new Kombilo pattern search engine into the source code repository. There are also some notes what this could be used for right now (and what does not yet work). All of this will eventually be integrated into a new Kombilo version, but for now is directed at programmers who want to use the pattern search engine in their own scripts or programs.

Kombilo 0.6 is approaching

I have been working intensely on the next Kombilo version, and although it is not yet done, I think I am pretty close to presenting something useful. The first priority now is to get the new pattern search engine finished. It will have the form of a "library", accessible from Python scripts, and later also from other programming languages.

It will take me some more time to adapt the graphical user interface and to create a Windows installer for the new version, but eventually this will of course come as well.

Kombilo patches ... my apologies

Apologies are due to Aloril and to Marcel GrĂ¼nauer, both of whom have sent me patches for Kombilo a long time ago. Whereas I had promised to at least put them on the Kombilo website I had not got around to actually doing so... Now they are available, at long last.
