71 Computer Chess

In May 1997, IBM's supercomputer, called Deep Blue, beat Gary Kasparov, the great chess player from Russia, in New York. This was the first time a supercomputer had ever beaten a man in traditional chess, although men had often lost to computers when playing speed chess. In traditional chess, players have as much time as they want for their moves, but in speed chess their time is limited.

The IBM computer is able to know between two and three million chess positions every second. It can make 100 billion moves in the time it takes a man to make one.

The first time Kasparov played Deep Blue was in Philadelphia in 1996. Kasparov won that first match. In May 1997 there was a match again, and Deep Blue won. Deep Blue got $700,000 for the game, and Kasparov took home $400,000. Now Kasparov wants to play a third match to decide who is the best player, but IBM says that Deep Blue has "retired?

計算機弈棋

1997年5月，IBM的超級計算機“深藍”在紐約擊敗了俄羅斯偉大的國際象棋大師卡斯帕羅夫。雖然下快棋時人們經常輸給計算機，但這是超級計算機在傳統棋類上第一次擊敗人類。在下傳統棋時，棋手有足夠的時間考慮再出棋，而下快棋時思考時間是有限的。IBM的計算機每秒可以計算200萬到300萬手棋，可以在人走一步棋所需的時間里走1 000億步棋。 1996年，卡斯帕羅夫在費城第一次與“深藍”交手，卡斯帕羅夫贏得了比賽。1997年5月，他們又進行了一次比賽，這次“深藍”贏了。從這場比賽中“深藍”贏得了70萬美元的獎金，而卡斯帕羅夫也將40萬美元收至囊中?，F在卡斯帕羅夫想進行第三次比賽來看誰才是最好的棋手，而IBM說“深藍”已經退休了。
