Computer teaches other computer how to play Pac-Man

Children of the 1980s spent hours perfecting the art of playing Namco’s Pac-Man computer game. And now computers are teaching each other to play the popular game, which sees a player navigating a maze, trying to gobble up pellets while avoiding four colourful enemies. Researchers have managed to develop a method to allow a computer to give advice and teach skills to another computer in a way that mimics how a real teacher and student might interact – and are demonstrating it with video games.
