Die Mechanismen hinter dem KI-Bot, der ein Team aus Pokerpros vor knapp einem Jahr alt aussehen ließ, wurden nun in einem. Das US-Verteidigungsministerium hat einen Zweijahresvertrag mit den Entwicklern der künstlichen Intelligenz (KI) „Libratus“ abgeschlossen. Tuomas Sandholm und seine Mitstreiter haben Details zu ihrer Poker-KI Libratus veröffentlicht, die jüngst vier Profispieler deutlich geschlagen.
Künstliche Intelligenz: Poker-KI Libratus kennt kein Deep Learning, ist aber ein MultitalentDie "Brains Vs. Artificial Intelligence: Upping the Ante" Challenge im Rivers Casino in Pittsburgh ist beendet. Poker-Bot Libratus hat sich nach. Im Jahr war es der KI Libratus gelungen, einen Poker-Profi bei einer Partie Texas-Hold'em ohne Limit zu schlagen. Diese Spielform gilt. Tuomas Sandholm und seine Mitstreiter haben Details zu ihrer Poker-KI Libratus veröffentlicht, die jüngst vier Profispieler deutlich geschlagen.

Get Poker Tracker 4 and start using it to win, then add on to it for your niche, like sit n goes, tournaments, cash games… Do it seriously.
As Libratus shows computer software analyzing play is the way to get a jump on your opponents like this computer did against the non software using human opponents.
We like em both, Poker Tracker and Holdem Manager. The Poker Hand Man picks Poker Tracker 4 but you may also be able to beat him using Holdem Manager, but you wont beat him or anyone else consistently and profitably without one of them.
Although we may be okay in online poker vs machines for now if you are however getting the least bit nervous about Libratus and Poker Bots like it, and do not want to invest the small amount required for a HUD, then Switch to Live Poker Tournaments.
Remember that the next time you wonder why you are getting raised and bet off of hands, losing hands on turn and river cards, and not getting max value from your monster hands, its probably because your opponent is like Libratus and knows all about your play from a PokerTracker Best Poker Hud.
Nobody in their right mind will agree to play a game of chess for a significant amount of money online. It's possible and probable to be up against some unbeatable AI.
Online Chess for fun? Sure thing! For money? But online poker is currently all about money and at some point in the future it is very likely that even the best security measures by the operators will no longer ensure a bot-free environment.
It's only a matter of time before online poker will have to evolve to a new form if it doesn't want to perish. And we're not talking about decades here, but years.
I'm no rocket scientist but I assume that anything with computers grows exponentially. Play Here. The victors - Brown left and Sandholm right.
Kim by far most successful. It was decisive. Powered by Bridges. Is our Deep Blue found? Just the beginning.
Deep Blue. Can already play this thing. Still OK for now. Comment on that Cancel reply Message. Your Name. Your message is awaiting approval.
Player 2 sees the bet but does not know what cards player 1 has. In the game tree, this is denoted by the information set , or the dashed line between the two states.
An information set is a collection of game states that a player cannot distinguish between when making decisions, so by definition a player must have the same strategy among states within each information set.
Thus, imperfect information makes a crucial difference in the decision-making process. To decide their next action, player 2 needs to evaluate the possibility of all possible underlying states which means all possible hands of player 1.
Because the player 1 is making decisions as well, if player 2 changes strategy, player 1 may change as well, and player 2 needs to update their beliefs about what player 1 would do.
Heads up means that there are only two players playing against each other, making the game a two-player zero sum game.
No-limit means that there are no restrictions on the bets you are allowed to make, meaning that the number of possible actions is enormous. In contrast, limit poker forces players to bet in fixed increments and was solved in .
Nevertheless, it is quite costly and wasteful to construct a new betting strategy for a single-dollar difference in the bet.
Libratus abstracts the game state by grouping the bets and other similar actions using an abstraction called a blueprint. In a blueprint, similar bets are be treated as the same and so are similar card combinations e.
Ace and 6 vs. Ace and 5. The blueprint is orders of magnitude smaller than the possible number of states in a game.
Libratus solves the blueprint using counterfactual regret minimization CFR , an iterative, linear time algorithm that solves for Nash equilibria in extensive form games.
Libratus uses a Monte Carlo-based variant that samples the game tree to get an approximate return for the subgame rather than enumerating every leaf node of the game tree.
It expands the game tree in real time and solves that subgame, going off the blueprint if the search finds a better action. Solving the subgame is more difficult than it may appear at first since different subtrees in the game state are not independent in an imperfect information game, preventing the subgame from being solved in isolation.
This decouples the problem and allows one to compute a best strategy for the subgame independently. In short, this ensures that for any possible situation, the opponent is no better-off reaching the subgame after the new strategy is computed.
Thus, it is guaranteed that the new strategy is no worse than the current strategy. Like its predecessor, its name is a Latin expression and means 'balanced'.
Libratus was built with more than 15 million core hours of computation as compared to million for Claudico. The computations were carried out on the new 'Bridges' supercomputer at the Pittsburgh Supercomputing Center.
According to one of Libratus' creators, Professor Tuomas Sandholm, Libratus does not have a fixed built-in strategy, but an algorithm that computes the strategy.
Their new method gets rid of the prior de facto standard in Poker programming, called "action mapping". As Libratus plays only against one other human or computer player, the special 'heads up' rules for two-player Texas hold 'em are enforced.
To manage the extra volume, the duration of the tournament was increased from 13 to 20 days. The four players were grouped into two subteams of two players each.
