Abstract

It was in 1990, when I was still studying my degree in Computer Science, when I met Prof. Lotfi Zadeh for the first time, if I do not remember wrongly. It was in a conference I was participating in Barcelona where he gave one of the plenary talks. I remember clearly that he mentioned fuzzy systems and the successful Japanese applications of the late 80es. I have always used the applications of fuzzy systems in class as an example of successful applications of artificial intelligence and related technologies. © 2013 Springer-Verlag Berlin Heidelberg.
