	Has anyone around here used Fuzzy Logic?

	My understanding of it is that, in it, predicates may not only
be "true" or "false" but anywhere in between. If 0 is false and 1 is
true, then the truth-value of a predicate will lie between 0 and 1
inclusive of the two limits.

	It turns out that one can define the operations "not", "and"
and "or"; one can even define several pairs of the latter two
operations.

	It is said to be used extensively in Japan, and it appears to
outperform decision systems based on predicate values being only 0 or
1. For instance a fuzzy-logic train controller is said to give a very
smooth ride there.

	Is this going to be another field in which the Japanese are
going to leave us behind?

	Has anyone thought of developing fuzzy-logic expert systems?
