AI victory over pro poker players hailed as milestone as computer learns to successfully trick humans

Artificial intelligence has reached a new milestone, with a program beating four professional players in a poker tournament lasting 20 days. Libratus, an AI program developed by a team of researchers at Carnegie Mellon University, took on Dong Kim, Jimmy Chou, Daniel McAulay and Jason Les at no-limit Texas Hold'em in a Pittsburgh casino, eventually taking $1.76 million (£1.4 million) in chips. It's been hailed as a milestone for AI, with Libratus co-creator Tuomas Sandholm declaring, "The best AI's ability to do strategic reasoning with imperfect information has now surpassed that of the best humans." Boston Dynamics describes itself as'building dynamic robots and software for human simulation'. It has created robots for DARPA, the US' military research company Deep Blue, a computer created by IBM, won a match against world champion Garry Kasparov in 1997. Apple's virtual assistant for iPhone, Siri, uses artificial intelligence technology to anticipate users' needs and give cheeky reactions Xbox's Kinect uses artificial intelligence to predict where players are likely to go, an track their movement more accurately Its human opponents had been sharing notes in an effort to expose Libratus' weaknesses, but the AI grew stronger as the tournament went on.
