Ke Jie has reached the limit, and AlphaGo is still rising, how can this be enough? On May 23, the second season of the much-anticipated human-machine war began, in the first game of Ke Jie and AlphaGo's three-game chess match, the black Ke Jie fought with 289 hands, and finally lost with the smallest gap of a quarter, and the first master of human Go is still difficult to climb the mountain of artificial intelligence. It seems to be the smallest gap, but in terms of content, it is the process of AlphaGo's victory. Ke Jie has been struggling to support after falling into passivity in the first half of the game, he played well in the second half of the game, so that the chess game was once confusing, but AlphaGo's control ability was too strong, and in the end Ke Jie was still unable to break through the thick wall.
