If fuzzy logic wasn't already an established term, and used in many fields of engineering and programming systems, then I might sound more like a fangirl, but it is established, and used in more applications than I can yet expound upon. Again, the term is new, but the idea is old.
No one told you that it wasn't used for a lof of things. But like every AI system it's a tool. And as with all tools they have specific uses.I wouldn't use Fuzzy logic to solve tic tac toe and i wouldn't use a screwdriver to fell a tree.
second post addressed to me[...]
No they do not assume that. With the rules we explained regarding tic tac toe, what the opponent play doesn't matter. If he play more or less correctly he'll get a draw, if not he'll loose period.
The chess analogy isn't relevant and it's off topic, and you may want to read a bit more about the logic systemS used in chess before jumping to conclusion.
