So the software must go through every possible move before it decides.Īlso, although Cepheus is unbeatable, it’s not the best player in the world. For example, you wouldn’t move your king early in the game unless it becomes absolutely necessary. Humans can rule out the vast majority of moves as they are obviously wrong. However, that’s also where one of the software’s weaknesses lies. Did you see the number above? That’s 316 quadrillion! Just like Deep Blue, Cepheus is way superior to the ordinary human mind when it comes to calculations.Ĭomputer software can go through a myriad of situations at ridiculous speed. Cepheus: Way Superior to Ordinary Human Mind

But in the long run, nobody should be able to beat it. It will get bad beats just as anyone else. Of course, Cepheus doesn’t win all the time. That makes the software as unpredictable as a human player. Instead, theory will tell you that in a specific situation you should call 70% of the times and fold in 30%, for example.Ĭepheus doesn’t make a decision here its action is determined by the random generator. The reason why it's mimicking human play so well is because it’s using a random generator for certain situations.Īs you know, in poker, there is often no single right answer. The machine went from making completely arbitrary decisions to playing reasonably and then, eventually, perfect. 200 processors took 70 days of calculations and generated a data base of 11 terabytes. They saved every single possible situation of a poker game – in a heads-up game, that’s 316.000.000.000.000.000 different situations (!) - and then had the machine play against a copy of itself. Project leader Mike Howling and his team have used adaptive software. Is Cepheus poker's Deep Blue? Not really.
