The three parameters listed at the end of the file are the averaging flag, the
defuzzification parameter, and the summation flag. When the averaging flag is set
to 1, the average of the input membership values ANDed together is output. When
the defuzzification parameter is 1, the “no overlap” method of defuzzification is
used. When the summation flag is set to 1, the maximum value caused by any one
rule firing is the value passed to defuzzification. These three parameters are the
same as those used in the rule generation stage.
The evolutionary fuzzy rule system is a powerful tool for evolving rules and
developing a fuzzy rule system for classification ...
