So Fuzzy Wuzzy wasn't very fuzzy. I t would be unfortunate if one only regarded fuzzy logic about as seriously as he or she regards the above children's poem. Though it sports an unconventional name, fuzzy logic is a field that has risen to the forefront of modern technology. Fuzzy technology was first developed in the United States, but it has truly bloomed into a billion dollar industry in Japan. The U.S., by some estimates, trails Japan by ten years in developing fuzzy logic applications.
Fuzzy logic is a mathematical approach to problem solving.
It excels in producing exact results from imprecise data, and is especially useful in computers and electronic applications. Fuzzy logic differs from classical logic in that statements are no longer black or white, true or false, on or off. The human brain can reason with uncertainties, vagueness, and judgments. Computers can only manipulate precise valuations. Fuzzy logic is an attempt to combine the two techniques.
