Poker Mensch gegen Maschine: Libratus, der GangsterDas US-Verteidigungsministerium hat einen Zweijahresvertrag mit den Entwicklern der künstlichen Intelligenz (KI) „Libratus“ abgeschlossen. Die vorgestellten Poker-Programme Libratus (ebenfalls von Sandholm und Brown) [a] und DeepStack [b] konnten zwar erstmals.

Libratus Poker Menu de navigation Video6 Libratus vs Preflop 3 Bet Tuomas Sandholm und seine Mitstreiter haben Details zu ihrer Poker-KI Libratus veröffentlicht, die jüngst vier Profispieler deutlich geschlagen. Poker-Software Libratus "Hätte die Maschine ein Persönlichkeitsprofil, dann Gangster". Eine künstliche Intelligenz hat erfolgreicher gepokert. Our goal was to replicate Libratus from a article published in Science titled Superhuman AI for heads-up no-limit poker: Libratus beats top professionals. Im Jahr war es der KI Libratus gelungen, einen Poker-Profi bei einer Partie Texas-Hold'em ohne Limit zu schlagen. Diese Spielform gilt.
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.
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. A Suggestion: You could stop playing heads up poker tournament games and forget all about ai super computer poker playing money stealing bots.
I never did like heads up poker myself anyway. Maybe these poker player professionals should have done something different every hand like the best poker bot known as Libratus was doing.
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.
A new gui to help it recognize new tables ia available as well. Use Partypoker standard setup.
Currently, the bot only works on tables with 6 people and where the bot is always sat at the bottom right. Put the partypoker client inside the VM and the bot outside the VM.
Put them next to each other so that the bot can see the full table of Partypoker. In setup choose Direct Mouse Control. 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.
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. The scary fact is: Bots don't even have to play a perfect strategy.
And they don't have to beat the best players. To make an impact they just have to beat the average player. And there's bad news on that front: We're there already.
For virtually any poker game there already is a bot that plays better than the average, decent human player. So while poker in general might not yet be solved in a theoretical sense, it's solved enough for a decent bot to beat a decent player.
The same phenomena was visible when computer chess was developed. In fact the first time a computer reached an ELO rating comparable to a master rank was in -- 16 years before the AI eventually beat the world champion.
The answer is twofold as one has to distinguish between live and online poker. It also has to be noted that the problem the poker industry is facing is not new at all.
The Libratus victory is not the first time bots demonstrated their ability to beat decent human players. The bot didn't take any rake; it simply made money by beating the players.
In online poker decent bots have been around at least eight years now and all reputable sites disallow the usage of the. Any players caught using them have their winnings confiscated and affected players are reimbursed.
Therefore, it was able to continuously straighten out the imperfections that the human team had discovered in their extensive analysis, resulting in a permanent arms race between the humans and Libratus.
It used another 4 million core hours on the Bridges supercomputer for the competition's purposes. Libratus had been leading against the human players from day one of the tournament.
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.Ich bin kein Wissenschaftler, aber ich glaube bei Computern wächst alles exponentiell. Es ist die Aufgabe der Pokeranbieter, sicherzustellen, dass Poker auf einem ausgeglichenen und fairen Terrain ausgetragen wird. Libratus ging also gut Wettbüros öffnen Wieder in das Match.

Libratus Game abstraction. Libratus played a poker variant called heads up no-limit Texas Hold’em. Heads up means that there are Solving the blueprint. The blueprint is orders of magnitude smaller than the possible number of states in a game. Nested safe subgame solving. While it’s true that the. 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. bspice(through)highdesertcorvettes.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.
