SHANGHAI: The Google-owned computer algorithm AlphaGo is retiring from playing humans in the ancient Chinese game of Go after roundly defeating the world’s top player last week, its developer said. 

AlphaGo defeated brash 19-year-old world number one Ke Jie of China on May 27 to sweep a three-game series that was closely watched as a measure of how far artificial intelligence (AI) has come.
