Cepheus (poker bot)

Cepheus is the first poker playing program that "weakly solved" the game of heads-up limit Texas hold 'em.[1][2][3]. It was developed by the Computer Poker Research Group (CPRG) at the University of Alberta and it was introduced in January 2015 in the paper written entitled "Heads-up limit hold’em poker is solved", published in Science[4]. Michael Bowling, Neil Burch, Michael Johanson, and Oskari Tammelin are the authors of such paper.

Cepheus' strategy is very close to a Nash equilibrium strategy for heads-up limit Texas hold'em, as an optimal counter-strategy to Cepheus can only win 0.000986 big blinds per game on expectation (to go from "weakly" solving the game to just "solving" the game one has to transform 0.000986 in 0.0000000 big blinds per game on expectation). However, 0.000986 big blinds per game on expectation means that even if someone plays against Cepheus for a lifetime this person will not be able to say, with statistical significance, that s/he has won.

Public web access to observe and play against Cepheus is available.[5]
