In March 2016 a Google computer program beat the best Go players in the world. Go is believed to be the most complex board game ever created. Is this computer program smarter than a person? Well, it did beat the South Korean Go master Lee Se-dol, and Lee was surprised by the result. He acknowledged defeat after three and a half hours of play. Demis Hassabis, who made the Google program, called it an important moment in history, because a machine beat the best person in the world in an intelligent game. Such computer programs rely on what is called artificial intelligence. Go is a two-player game of strategy said to have had an origin in China perhaps around 3,000 [three thousand] years ago. Players compete to win more territory by placing black and white “stones” on a board made up of 19 [nineteen] lines by 19 [nineteen] lines.
