周四，谷歌人工智能程序AlphaGo在与韩国围棋高手李世石的最后一场比赛中获胜，最终以4-1的比分赢得这场总计五局的人机大赛。

Lee Se-dol, one of the world's top Go players, won just one of the matches against the AlphaGo program, missing out on the $1m prize up for grabs. Demis Hassabis, founder of DeepMind, said the match had been the "most exciting and stressful" for his team.

世界顶级围棋选手之一的李世石，在与AlphaGo程序的较量中只赢了一场，从而与100万美元的奖金失之交臂。DeepMind创始人戴密斯·哈萨比斯则称这一系列赛对于他的团队来说是“最令人激动和紧张”的。

Lee said he felt "regrettable" about the result of the contest after the game.

赛后，李世石表示对比赛结果感到"遗憾"。

AlphaGo击败李世石被授名誉九段

At a press conference held after the final match, Mr Lee said he did not necessarily think AlphaGo was superior to humans. But he said he had more studying to do, and admitted the matches had challenged some of his ideas about the game Go.

在最后一场比赛结束之后的新闻发布会中，李世石表示，他并不认为AlphaGo优于人类。但他也表示自己有很多功课要做，并承认这次比赛改变了他对围棋的一些想法。

One South Korean newspaper complained that the contest was "lopsided" with the single Korean pitted against the corporate might of Google and its "army of super-smart people armed with unfathomable computing power".

一家韩国报纸对此抱怨称，这场比赛是一个孤军奋战的韩国人来和整个谷歌公司的力量以及“一群有着深不可测的计算机实力的超级聪明人”的较量，而这显然是不公平的。

In a spirit of magnanimity, however, the Korea Baduk Association - which governs the game of Go - has decided to give an honorary ninth-dan ranking to AlphaGo.

然而，秉持着大度的精神，管理围棋的韩国棋院决定授予AlphaGo名誉职业九段的排名。

The 4-1 mechanical victory has also made some Go players doubt themselves. Go was invented about 2,500 years or so ago in China. Until now, it has always had a human best player. Not any more.

这场4比1的机械性胜利也让一些围棋选手产生自我怀疑。围棋在大约2500年前起源于中国。之前，最好的棋手都是人类。但再也不是了。

AlphaGo's win over Lee is significant because it marks the first time an AI program has beaten a top-ranked Go professional, a victory experts had predicted was still years away.

AlphaGo战胜李世石一役意义重大，因为这标志着人工智能程序首次击败顶尖围棋职业选手。此前专家预计数年后才会出现这样的结果。
