what exactly is it? i bought a book called 'fuzzy logic' from barnes&noble out of curiosity. (i had heard the term before.) it's about dealing with logical problems realistically, instead of abstracting uncertainty behind a wall of certainty through probability.
what i don't understand is how it differs from normal computer science. it seems to me to be an 'if-then' approach to problem solving instead of using algorithms... but don't computers do that already?
