The term ‘soft computing’ means the final result of computation based on imperfect
information is tolerant to imprecision, uncertainty and partial truth. The final result of
computation, which is usually represented by a fuzzy set, can be flexibly interpreted
(depending upon the process of defuzzification) as per the need of the problem at
hand. The basic feature ‘tolerance’ is the hallmark of the method of soft computing
by which it is different from the existing approach to computing (the so-called hard
computing), which is essentially based on the data/information of perfect measure-
ment and whose semantic is either true or false. The topic ...
