Die "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. Ist Poker für uns Menschen erledigt? Welchen Einfluss wird der eindrucksvolle Erfolg von Libratus auf das Pokerspiel haben? Dieser Artikel wird.
Poker-KI Pluribus schlägt menschliche Profis im Texas Hold‘em mit sechs SpielernIm 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. Das US-Verteidigungsministerium hat einen Zweijahresvertrag mit den Entwicklern der künstlichen Intelligenz (KI) „Libratus“ abgeschlossen.
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. Click here to see a Video description how to add a new table.
It will be hard for one person alone to beat the world at poker. That's why this repo aims to have a collaborative environment, where models can be added and evaluated.

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.
One of the subteams was playing in the open, while the other subteam was located in a separate room nicknamed 'The Dungeon' where no mobile phones or other external communications were allowed.
The Dungeon subteam got the same sequence of cards as was being dealt in the open, except that the sides were switched: The Dungeon humans got the cards that the AI got in the open and vice versa.
Libratus was well prepared for the challenge but the learning didn't stop there. Each day after the matches against its human counterparts it adjusted its strategies to exploit any weaknesses it found in the human strategies, increasing its leverage.
How can a computer beat seemingly strong poker players? Unlike Chess or Go, poker is a game with incomplete information and lots of randomness involved.
How can a computer excel at such a game? First, one needs to understand that while poker is a very complex game — much more complex than Chess or even Go — its complexity is limited.
There are only so many different ways the cards can be shuffled and only so many possible different distinguishable games to be played.
To put this in numbers: In Heads-Up Limit-Hold'em there are roughly ,,,,, different game situations.
If you played out one of them per second, you'd need 10 billion years to finish them all. That's a lot of game situations.
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.
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.
