Cepheus is a computer poker program developed by the University of Alberta’s Computer Poker Research Group. Cepheus has been unbeatable since it was first released in 2015, and its success has led to a new era of artificial intelligence research.
This program is unique in that it uses game theory rather than brute force methods to make decisions about which moves to make during a game. Cepheus evaluates every possible hand combination and computes the optimal move for each one, taking into account both the probability of winning and the expected rewards from each action. In this way, Cepheus is able to accurately predict how an opponent will respond in any given situation and plan accordingly.
What makes Cepheus so impressive is its ability to learn from its past experiences and constantly improve. Cepheus uses a machine learning algorithm known as “counterfactual regret minimization” that allows it to adjust its strategy based on how previous hands have played out. This means Cepheus can quickly adapt when playing against different styles of opponents, making it an incredibly difficult opponent for even the most experienced poker player.
Cepheus has been tested by some of the world’s best poker players and has proven itself to be nearly impossible to beat. It continues to act as an important benchmark in AI research and is likely to remain at the forefront of computer poker development for years to come. If you ever find yourself in an online poker game, it may be Cepheus you are up against. Good luck!
