Abstract:

Texas Hold’empoker is a good research subject in the field of machine games. Different from chess and checkers, it involves many fields such as imperfect information process, multiple competing agents, risk assessment and opponent modeling. Among these areas, the most basic research is imperfect information process, which abstracts useful information for later phases of machine games. We introduce several methods for evaluating Texas Hold’em poker with imperfect information and propose a new method to improve computation speed and decrease the resources consumption. Experimental results show that the new method saves the space and has a faster calculation speed because it abandons the lookup table.
