According to an article about the DB match (linked elsewhere on this board),

"Now that the match is over, a few pieces of information about Deep Blue's
preparations are beginning to emerge. Besides Grandmaster Joel Benjamin, Deep
Blue was tested by several New York-based grandmasters as well as Spanish
Grandmaster Miguel Illescas. Other researchers at IBM's T.J. Watson facility
were apparently brought into the project. ** For example, Gerry Tesauro, best
known for his program TD-Gammon (playing at a level on par with the best
backgammon players), used his neural net technology to help tune Deep Blue's
evaluation function. ** The biggest strides forward seemed to be in the
evaluation function, where extensive efforts were spent trying to improve the
program's play in positions where computers have a reputation for playing weakly
in. As far as we can tell from a small sample of six games, the Deep Blue team
have made significant strides here."

** emphasis added.  In principle I didn't see any reason why the evolutionary
neural net approach wouldn't work for evaluation tuning, and according to this
article this approach had been used to some extent for DB.
