IBM announces improved chess-playing supercomputer
After its Deep Blue chess-playing computer defeated human world chess champion Gary Kasparov in a closely watched match in May, the pioneering computer company decided to make the machine even faster and stronger. On September 2, IBM announced that its RS/6000 SP model, a parallel supercomputer, was now 58 percent faster thanks to a new microprocessor and some software refinements. Kasparov was not available for comment.
