By playing itself over and over again, AlphaGo Zero (AGZ) trained itself to play Go from scratch in just three days and soundly defeated the original AlphaGo 100 games to 0.

Not content to rest on its laurels, AlphaGo got a major upgrade last year, becoming capable of teaching itself winning strategies with no need for human intervention. AdvertisementĪlphaZero is a direct descendent of DeepMind's AlphaGo, which made headlines worldwide in 2016 by defeating Lee Sedol, the reigning (human) world champion in Go.
That makes it an ideal testing ground for AI. It's a surprisingly complicated game, much more difficult than chess, despite only involving two players with a fairly simple set of ground rules. So AI researchers turned their attention in recent years to creating programs that can master the game of Go, a hugely popular board game in East Asia that dates back more than 2,500 years. Many other computer chess programs followed, each a little better than the last, until IBM's Deep Blue computer defeated chess grand master Garry Kasparov in May 1997.Īs Kasparov points out in an accompanying editorial in Science, these days your average smartphone chess playing app is far more powerful than Deep Blue. Greenblatt's Mac Hack IV program was the first to play in a human chess tournament-and to win against a human in tournament play. The very first chess computer program was written in the 1950s at Los Alamos National Laboratory, and in the late 1960s, Richard D.

"In that sense, it is free from the constraints of the way humans think about the game."Ĭhess has long been an ideal testing ground for game-playing computers and the development of AI. Dubbed AlphaZero, this program taught itself to play three different board games (chess, Go, and shogi, a Japanese form of chess) in just three days, with no human intervention.Ī paper describing the achievement was just published in Science. "Starting from totally random play, AlphaZero gradually learns what good play looks like and forms its own evaluations about the game," said Demis Hassabis, CEO and co-founder of DeepMind. Google's DeepMind-the group that brought you the champion game-playing AIs AlphaGo and AlphaGoZero-is back with a new, improved, and more-generalized version.
