| Post subject: | Fastest 7 card hand evaluator? |
After trying my hand at writing a hand evaluator in Java and getting some poor results I've been looking around at what other people have done. From what I can make out the Ray W 2+2 algorithm (from years back) is the best. Is this still the case? If it is does anyone have code that shows how it is used? I have the PerformanceTest2 class (viewtopic.php?f=24&t=2390) bundled with the code but it doesn't really show how the hands are created and evaluated. Thanks Leon |

Thanks for the reply. I thought I had but now I see it was a treasuretrove. I've got something up and running now giving several million evaluations a second. I wanted to benchmark against Pokerstove with hero having AA and villian having 100% range. I think this is 2,598,960 * 1,326 ~3.5 billion combinations. Pokertove completes this enumeration in a second claiming several billion games per second. I don't see how I can ever get near this figure, at the moment my program takes several minutes. When Pokerstove switches to Montecarlo it suddenly drops to millions of games per second. I can only assume Pokerstove has some clever way of discounting some of those billion combinations in evaluate mode? Do you know? |

Andrew Prock did vaguely describe it once but I can't find it now. I have a suspicion that you can't use that approach for all possible problems though. The source is out there. |
