IBM Says It Has Retired Deep Blue

IBM has retired Deep Blue, the supercomputer that made history when it defeated world chess champion Garry Kasparov in May, a company spokeswoman said. “What we told Garry Kasparov is that we do not anticipate a rematch in the foreseeable future,” IBM spokeswoman Melinda McMullen said. “Our scientists said they really did want to move on to other grand challenges and the company wants to.” Russian grandmaster Kasparov, world champion since 1985, said in a statement from his home in Moscow that he was “very disappointed.” He had asked for a winner-take-all rematch.
