Cool work. Do you plan to support large games, such as Texas Hold'em? about open_spiel HOT 8 CLOSED

Cool work ！The ACPC code ([http://www.computerpokercompetition.org/downloads/code/competition_server/project_acpc_server_v1.0.42.tar.bz2]) is pretty good for poker engine

Hey all!

Thank you very much for your interest in OpenSpiel. I lead the Swift for TensorFlow project in Google Brain and collaborated with @lanctot and many others across both Brain and DeepMind to help make OpenSpiel. When I saw the recent research results coming out using Texas Hold'em, I built a game implementation for OpenSpiel. Unfortunately, I had some edge cases in the game engine that we discovered late, so we held it back from the initial release. Earlier this week, I fixed it up and so @lanctot has now open sourced it at https://github.com/deepmind/open_spiel/blob/master/swift/Sources/OpenSpiel/TexasHoldem.swift (I also spent some time last night and optimized the game engine a bit, dropping the time to play a round from 8.4 usec down to 4.7 usec.) :-)

I and others will be discussing the design of the Swift OpenSpiel port at the Swift for TensorFlow Open Design Review this Friday (tomorrow). Please do join if you're able and ask us questions! (A recording will be made and posted later.) To get the invite, join [email protected].

All the best,

Thanks! I would say that Chess, Go, and Backgammon are large :)

Actually, we currently have a Swift implementation of Texas Hold'em in the works.

There is nothing preventing large imperfect information games, in general, though. We just didn't have anyone (other than Brennan!) volunteer to write any. A C++ Texas Hold'em implementation would be very welcome!

wow, that's great. I plan to use this toolbox and do some experiments.

Writing Texas Hold'em solver in pure C/C++ needs a lot of effort. Looking forward.

from open_spiel.

True. I am hoping someone already has one they are willing to adapt and share.

Perhaps our good friend Noam Brown? ;-)

from open_spiel.

Yes, Noam Brown implemented Texas Hold'em solver in pure C/C++. I meet him in IJCAI 2019.

It can imagine there are a lot of codes in his solver. Reimplementation of such difficult game needs a lot time.

Hi all!

I have an implementation of a Poker gameengine based on the ACPC-Server with a very similar API to open_spiel.

I think I'll be able to contribute it as a pull request.

Are there any style guidelines and rules for contribution? How can I contact you in case of questions?

Geetings,

Now implemeted an adapter for my previous code and made everything compile. Game unit tests are running, but no observations and information sets.

Code is incubating here

Feedback and contributions welcome :-)
