Libratus Poker Bot vernichtet menschliche Gegner – Der Anfang vom Ende?Poker-Software Libratus "Hätte die Maschine ein Persönlichkeitsprofil, dann Gangster". Eine künstliche Intelligenz hat erfolgreicher gepokert. Die vorgestellten Poker-Programme Libratus (ebenfalls von Sandholm und Brown) [a] und DeepStack [b] konnten zwar erstmals. Das US-Verteidigungsministerium hat einen Zweijahresvertrag mit den Entwicklern der künstlichen Intelligenz (KI) „Libratus“ abgeschlossen.

Libratus Poker - Vielleicht hatte der Bot einfach nur eine Menge Glück?Welche Absicht steckt hinter dem Versuch und wie sollen die zehn Millionen zurück in Blick English Kasse kommen? In a stunning victory completed tonight the Libratus Poker AI, created by Noam Brown et al. at Carnegie Mellon University, has beaten four human professional players at No-Limit Hold'em. For the first time in history, the poker-playing world is facing a future of machines taking over the game of No-Limit Holdem. Libratus emerged as the clear victor after playing more than , hands in a heads-up no-limit Texas hold ’em poker tournament back in February. The machine crushed its meatbag opponents by big blinds per game, drawing in $1,, in prize money. Now, a paper published in Science reveals how Libratus was programmed. The approach taken by its creators Noam Brown, a PhD student, and Tuomas Sandholm, a professor of computer science, both at Carnegie Mellon University in the US. Libratus is an artificial intelligence computer program designed to play poker, specifically heads up no-limit Texas hold 'em. Libratus' creators intend for it to be generalisable to other, non-Poker-specific applications. It was developed at Carnegie Mellon University, Pittsburgh. bspice(through)kulturyayinlari.com Libratus, an artificial intelligence developed by Carnegie Mellon University, made history by defeating four of the world’s best professional poker players in a marathon day poker competition, called “Brains Vs. Artificial Intelligence: Upping the Ante” at Rivers Casino in Pittsburgh. Pitting artificial intelligence (AI) against top human players demonstrates just how far AI has come. Brown and Sandholm built a poker-playing AI called Libratus that decisively beat four leading.
For No-Limit the number is some orders of magnitude higher since you can bet almost arbitrarily large amounts, but the matter of fact is that the total number of different game situations is finite.
A Nash Equilibrium is a strategy which ensures that the player who is using it will, at the very least, not fare worse than a player using any other strategy.
In layman's terms: Playing the Nash equilibrium strategy means you cannot lose against any other player in the long run. The existence of those equilibriums was proven by John Nash in and the proof earned him the Nobel Prize in Economics.
This Nash equilibrium means: Guts, reads and intuition don't matter in the end. There is perfect strategy for poker; we just have to find it.
All you need is a suitable computer which can handle quadrillions of different situations, works on millions of billions of terabyte of memory and is blazingly fast.
Then you put a team of sharp, clever humans in front of it, let them develop a method to utilize the computational power and you're there.
Right now Libratus is just the beginning. The AI still simplifies many different poker situations. For example it might not differentiate between a king-jack high flush-draw and a king-ten high flush-draw.
But Libratus is already close to having developed a perfect strategy — at least close enough to annihilate any human counterpart. Libratus beat humans in No-Limit Heads-Up.
Two years ago the University of Alberta introduced Cepheus to the world -- a bot which, for all intents and purposes, plays a perfect Limit Heads-Up strategy.
It's safe to say that those two variants are practically solved. As a matter of fact the guys from the University of Alberta managed to prove that their bot is at worst 0.
Nash equilibrium strategy. While The No-Limit bot Libratus might be much further away from this perfect strategy, it's only a matter of time before it'll be refined and get closer to it.
What about other poker variants? Poker with more than two players is orders of magnitudes more complex than heads-up.
The same holds true for more difficult variants like Omaha. But a bot like Libratus is still so complex it requires a direct connection to its enormous super computer while playing.
And it still plays remarkably slow. So there's no direct danger of it being used in your local casino or online game.
Mixing up play continuously instead of pounding on perceived weak holes. Who knows. Perhaps that all they could do out of frustration with the ai super computer beating them down continuously.
Because these tournament poker players playing against Libratus were adaptive and winning online poker players and always used huds to win online themselves against other players.
They noticed a big hole in their abilities when they did not have a hud against Libratus to help guide them like they were used to using against other human players.
Yet Libratus is one giant poker player HUD in of itself. It analyzed its own play and found its own holes as well as collecting stats and information on the human Poker players it played against.
Therefore Poker Huds offer an unfair advantage to those that have and use them vs. I felt like I was playing against someone who was cheating, like it could see my cards.
It was just that good. This is considered an exceptionally high winrate in poker and is highly statistically significant.
While Libratus' first application was to play poker, its designers have a much broader mission in mind for the AI. Because of this Sandholm and his colleagues are proposing to apply the system to other, real-world problems as well, including cybersecurity, business negotiations, or medical planning.

In contrast, games like poker are usually studied as extensive form games , a more general formalism where multiple actions take place one after another.
See Figure 1 for an example. All the possible games states are specified in the game tree. The good news about extensive form games is that they reduce to normal form games mathematically.
Since poker is a zero-sum extensive form game, it satisfies the minmax theorem and can be solved in polynomial time.
However, as the tree illustrates, the state space grows quickly as the game goes on. Even worse, while zero-sum games can be solved efficiently, a naive approach to extensive games is polynomial in the number of pure strategies and this number grows exponentially with the size of game tree.
Thus, finding an efficient representation of an extensive form game is a big challenge for game-playing agents. AlphaGo  famously used neural networks to represent the outcome of a subtree of Go.
While Go and poker are both extensive form games, the key difference between the two is that Go is a perfect information game, while poker is an imperfect information game.
In poker however, the state of the game depends on how the cards are dealt, and only some of the relevant cards are observed by every player.
To illustrate the difference, we look at Figure 2, a simplified game tree for poker. Note that players do not have perfect information and cannot see what cards have been dealt to the other player.
Let's suppose that Player 1 decides to bet. 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.
It will then take direct screenshots and move the mouse. If that works, you can try with direct VM control.
The bot may not work with play money as it's optimized on small stakes to read the numbers correctly.
The current version is compatible with Windows. Make sure that you don't use any dpi scaling, Otherwise the tables won't be recognized. Run the bot outside of this virtual machine.
As it works with image recognition make sure to not obstruct the view to the Poker software. Only one table window should be visible.
The decision is made by the Decision class in decisionmaker. A variety of factors are taken into consideration:.
After that regular expressions are used to further filter the results. This is not a satisfactory method and can lead to errors.
Ideally tesseract or any other OCR libary could be trained to recognize the numbers correctly.
