- Setup
- Grab the server from https://github.com/theaigames/poker-engine (i.e. git clone https://github.com/theaigames/poker-engine.git)
- Follow build instructions
- For non-Java people: make sure your JDK and JRE are the same or compatible versions (may be out of sync if your java packages on linux were just pulled in as dependencies any old way, like me)
java -versionandjavac -version
chmod 755 multibot.py- Test run, something like:
java -classpath /home/nick/projects/pokerbot/theaigames/poker-engine/bin nl.starapple.backend.RunPoker 2000 ./multibot.py ./multibot.py
- Details
- The engine exec()s the supplied commands as the 2 players and communicates via simple protocol on stdin/stdout. So you can use any language you want
- Protocol here http://theaigames.com/competitions/heads-up-omaha/getting-started#
- Engine does the second most popular variant of poker, PLO, by default (http://en.wikipedia.org/wiki/Omaha_hold_%27em), because it is a less solved game than the more popular No Limit Texas Holdem. Depending on what people want, we could go either way
- apply the seed_rng.patch to the theaigames engine to add RNG seed and game type commandline options (so you can have repeatable games for testing, and switch to NLH without recompiling all the time)
- With that patch, you can run for eg. java -classpath /home/nick/projects/pokerbot/theaigames/poker-engine/bin nl.starapple.backend.RunPoker 2000 "./pbots/multibot.py --game=NLH --bot-name=ExampleBot" "./pbots/multibot.py --game=NLH --bot-name=PairBot" 123 13 (123 being the RNG seed and 13 being the NLH game type)
- Evaluation
- Does the "score" say how many hands the match took? That's not a very good metric.
- % of games won over a large sample would be better
- Haven't decided how best for bot writers to compare their results without sharing code. % won against an agreed set of dumber bots?
- Visualisation
- eg. Create a log from player2's point of view that is readable by http://universal-replayer.net/ . Not using "special messages" feature (Have a bot print tagged messages for each hand to stderr for inclusion in the converted hand history, for debugging purposes)
