AAAI-18 Workshop on AI for Imperfect-Information Games: Call for Papers

The AAAI-18 Workshop on AI for Imperfect-Information Games will be held at AAAI-18 in New Orleans in February 2018. We invite you to come attend the workshop and welcome paper submissions (on computational poker or on any other topic related to imperfect-information games). Every year researchers and hobbyists interested in computational poker gather at this workshop to discuss in person the latest research and results. The deadline for paper submissions is October 13th. More details about the event can be found on the workshop web page: http://www.cs.cmu.edu/~noamb/aaai18/workshop.html.

 

Best, 

Noam Brown

2018 Call for Participation

The Annual Computer Poker Competition will be held again in February 2018. Noam Brown will be the incoming chair of the competition and Martin Schmid will be returning as the outgoing chairs. This time there will be a heads-up (two-player) no-limit Texas hold'em competition, and for the first time there will be a six-player no-limit Texas hold'em competition.

The plan is to use Amazon EC2 instances again this year, with a final submission deadline of December 20th 2017. Note that these machines are quite a bit less powerful than many desktop machines, so if computing resources are a significant issue for you, please check that this is adequate. The maximum submission size will remain the same at 250 GB this year for both the two-player and six-player competitions. The remaining technical specifications for the two-player competition remain the same as last year. The technical specifications for the six-player competition will be identical to the two-player competition, except that only 2 seconds per hand will be allowed rather than 7 (since each player will likely be involved in fewer hands). See http://aws.amazon.com/ec2/instance-types/ for details on Amazon instance types. It is possible to get access to a smaller testing instance through Amazon for free by creating an EC2 account, and all competitors will get access to a full sized competition machine for final testing at least one week prior to the final submission deadline.

Any individuals or teams that wish to participate should send an email by December 1, 2017 to This email address is being protected from spambots.

If you require any special software - anything that is not installed by default on an Amazon EC2 instance - please let us know by December 1, so we can try to make sure your requirements are met. Your expression of interest email is not a formal commitment, but allows us to plan for the time and resources required to run the competition.

2017 Call for Participation

The Annual Computer Poker Competition will be held again in 2017, during the month of January.  Martin Schmid will be the incoming chair of the competition for this year and Kevin Waugh will be returning as the outgoing chair.  This time, only the heads-up (two player) no-limit Texas Hold'em competition will be held.

The plan is to use Amazon EC2 instances again this year, with a final submission deadline of Friday January 13, 2017.  Note that these machines are quite a bit less powerful than many desktop machines, so if computing resources are a significant issue for you, please check that this is adequate.  We have increase the maximum submission size to 250 GB this year.  The remaining technical specifications remain the same as last year.  See http://aws.amazon.com/ec2/instance-types/ for details on Amazon instance types. It is possible to get access to a smaller testing instance through Amazon for free by creating an EC2 account, and all competitors will get access to a full sized competition machine for final testing at least one week prior to the final submission deadline.

AAAI-17 Workshop on Computer Poker and Imperfect Information: Call for Papers

I would like to invite you to attend and consider submitting papers for the AAAI-17 Workshop on Computer Poker and Imperfect Information Games. As you probably know, it is the main forum where people interested in computational poker regularly meet in person and discuss their research. The deadline for paper submissions is November 4 and more details about the event can be found on the workshop web page: https://sites.google.com/a/ualberta.ca/cpw2017/. Thank you for considering your participation.

Best regards,

2016 Results Amendment

Unfortunately, the results announced at AAAI 2016 workshop were erroneous.  In particular, the additional matches that were run to separate the top four agents, seeds 100 and higher, were biased as all these matches used the same sequence of cards.  We gratefully thank Vahe Hagopian who brought this to our attention.

This introduced bias invalidates the previously posted results for the Bankroll Instant Runoff competition, where in a sense it resulted in an effective sample size of two between the top agents.

To correct this error, additional matches between the top four, and subsequently the top two agents, were run.  The log files, crosstable and ordering have been corrected on the results page; an errata has been added; and measures to prevent this particular error from occurring again have been implemented.

The Bankroll Instant Runoff winners are:

  1. Baby Tartanian8 (Noam Brown and Tuomas Sandholm, CMU)
  2. Slumbot (Eric Jackson, Independent)
  3. Act1 (Tim Reiff, Independent)
