In a series of unofficial online games, an updated version of Google's AlphaGo artificial intelligence has compiled a 60-0 record against some of the game's premier players. Among the defeated, according to the Wall Street Journal, were China's Ke Jie, reigning world Go champion. The run follows AlphaGo's defeat of South Korea's Lee Se-dol in March of 2016, in a more official setting and using a previous version of the program. The games were played by the computer through online accounts dubbed Magister and Master--names that proved prophetic. As described by the Journal, the AI's strategies were unconventional and unpredictable, including moves that only revealed their full implications many turns later.
