Libratus Poker From Zero to Hero in 2 Years 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.
No hard all-ins. When a hand was all-in before the river no more cards were dealt and each player received his equity in chips.
This also reduced the luck factor. This equates to a win rate of All four human players lost over their 30, hands against Libratus.
This is how they performed individually:. While the rules of the challenge were set to reduce the luck factor as much as possible, chance still plays a big role in the results of each hand — even with mirrored hands and even with the elimination of all-in luck.
So maybe, just maybe, the human players are actually better but the AI just got lucky. Let's look at some statistics regarding the results.
The AI won with a win rate of Those are just rough estimates for the variance, but as we'll see they're good enough boundaries.
What's the probability of the humans actually playing better than the AI but losing at a rate of It turns out this probability is very low: Somewhere between 0.
Meaning: It's very, very unlikely the general result of this challenge — the AI plays better than four humans — is due to the AI just getting lucky.
No bad luck. Basically the Libratus AI is just a huge set of strategies which define how to play in a certain situation. Two examples of such strategies not necessarily related to the actual game play of Libratus :.
It quickly becomes obvious that there are almost uncountably many different situations the AI can be in and for each and every situation the AI has a strategy.
The AI effectively rolls a dice to decide what to do but the probabilities and actions are pre-calculated and well balanced.
The computer played for many days against itself, accumulating billions, probably trillions of hands and tried randomly all kinds of different strategies.
Whenever a strategy worked, the likelihood to play this strategy increased; whenever a strategy didn't work, the likelihood decreased.
Basically, generating the strategies was a colossal trial and error run. Prior to this competition, it had only played poker against itself.
It did not learn its strategy from human hand histories. Skip to content. Binaries can be downloaded with this link: sourceforge.

Failed to load latest commit information. Jun 1, Jun 14, Overnight it was perfecting its strategy on its own by analysing the prior gameplay and results of the day, particularly its losses.
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. This is your chance to get your own poker bot to read the other players hands.
Yup It appears so…. Libratus from its roots in Latin means to free, and in this case free us of our money. What does this mean for poker when a super computer wins poker tournaments vs humans?
Are we going to have to worry about bots in the future playing us online to take all our money in cash games?
How will we protect our online play against these super computer machines and bot technology once it becomes available mainstream?
Well for now I do not think we have to worry, although the way tech jumps forward in leaps and bounds you just do not know how long we will be safe from these super computer bots.
The Good News is that this ai best poker bot super computer was only able to win in heads up poker, and for now if your worried or may feel the need to be worried in the future, just avoid heads up poker as much as you can.
A Deep Q-network learns how to play under the reinforcement learning framework, where a single agent interacts with a fixed environment, possibly with imperfect information.
Also in , DeepMind's AlphaGo used similar deep reinforcement learning techniques to beat professionals at Go for the first time in history.
Go is the opposite of Atari games to some extent: while the game has perfect information , the challenge comes from the strategic interaction of multiple agents.
Libratus, on the other hand, is designed to operate in a scenario where multiple decision makers compete under imperfect information.
This makes it unique: poker is harder than games like chess and Go because of the imperfect information available.
At the same time, it's harder than other imperfect information games, like Atari games, because of the complex strategic interactions involved in multi-agent competition.
In Atari games, there may be a fixed strategy to "beat" the game, but as we'll discuss later, there is no fixed strategy to "beat" an opponent at poker.
This combined uncertainty in poker has historically been challenging for AI algorithms to deal with. That is, until Libratus came along.
Libratus used a game-theoretic approach to deal with the unique combination of multiple agents and imperfect information, and it explicitly considers the fact that a poker game involves both parties trying to maximize their own interests.
The poker variant that Libratus can play, no-limit heads up Texas Hold'em poker, is an extensive-form imperfect-information zero-sum game.
We will first briefly introduce these concepts from game theory. For our purposes, we will start with the normal form definition of a game.
The game concludes after a single turn. These games are called normal form because they only involve a single action. An extensive form game , like poker, consists of multiple turns.
Before we delve into that, we need to first have a notion of a good strategy. Multi-agent systems are far more complex than single-agent games.
To account for this, mathematicians use the concept of the Nash equilibrium. A Nash equilibrium is a scenario where none of the game participants can improve their outcome by changing only their own strategy.
This is because a rational player will change their actions to maximize their own game outcome. When the strategies of the players are at a Nash equilibrium, none of them can improve by changing his own.Libratus: The Superhuman AI for No-Limit Poker (Demonstration) Noam Brown Computer Science Department Carnegie Mellon University [email protected] Tuomas Sandholm Computer Science Department Carnegie Mellon University Strategic Machine, Inc.

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. 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. While the first program, Claudico, was summarily beaten by human poker players —“one broke-ass robot,” an observer called it — Libratus has triumphed in a series of one-on-one, or heads-up, matches against some of the best online players in the United States. Libratus relies on three main modules. bspice(through)gobsofgifts.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.
