Perhaps Garry Kasparov lost to a computer because of an error in the program

The defeat of Garry Kasparov Deep Blue computer in 1997 could be the result of a failure in the program. About this in his book, The Signal and the Noise writes statisticians and journalists The New York Times, Nate Silver.

For his book Nate Silver interviewed Murray Campbell, one of the creators of Deep Blue. Campbell said that the program of the computer error was detected. The program has been written in such a way that, if the waiting time stroke exceeds a certain threshold, the car turned to a random selection. According to Campbell, this behavior has been observed during the test, but the creators of the computer were confident that fixed the bug.

According to Campbell, the course of the first 44 games and became such a "random" way. In turn it is this move was perceived by Kasparov (and later on chess experts who analyzed the game) as an application for a fine strategy. Moreover, in an interview with Wired in 2001 Grandmaster Yasser Seirawan he called this move is very elegant, cutting off a counter. According Seirawan, this is the course "Kasparov knocked confused».

As a result, Kasparov began to make mistakes, because he was sure that Deep Blue was imprisoned for the game was against it - in 1996 he had already won an earlier version of the machine. Later, it was this move became the foundation for the rumors that the game interfered with the computer people. Those rumors intensified after Garry Kasparov demanded to give him a printout of logs party, and IBM did not do so.
