Question: Where can I find more GGP domains (kif files) ?

[guicho271828]

Dear GGP community,

I am Masataro Asai, a researcher specialized in heuristic search and PDDL-based planning.
Generally speaking, what is the best way to interact with people in this community?

I am looking for a centralized repository of the GGP domains (GDL / kif file database).
Competition servers only seem to provide game specifications through some HTTP interactions,
and this base repository seems to have only three domains (connect4, tic-tac-toe, maze).

Thank you,
Masataro

Hi Masataro,

There used to be an active GGP community that used forums including these bulletin boards and (briefly) this Slack channel, but around 2017 the critical mass of interest and activity was lost -- at least for the hobbyists. There's also a mailing list used mostly for infrequent academic announcements (e.g. calls for papers) at general-game-playing@lists.stanford.edu.

That said, the game collection that was hosted on Tiltyard (ggp.org) is still intact here: https://github.com/ggp-org/ggp-repository/tree/master/war/root/games

I tried to find the "Stanford" and "Dresden" collections, but their servers (https://ggp.stanford.edu/ and http://ggpserver.general-game-playing.de/) seem to be unusable. The ggp.org collection was the largest of the three, in any case.

You may also want to check out the Ludii project that was founded more recently.

Hope that helps,
Alex

Thanks for the answers.
I wonder how much academic focus is currently on Ludii ...
I should read the paper more deeply (esp. re: generality section),
but the module system doesn't quite sound like making a theoretical difference from GDL and
I get a (again, probably not well-founded) impression that it is a casual and educational modeling environment.
