fuzzy classification program?

Hello,

I am searching for a freely available program for generating
classification rules using fuzzy and/or genetic algorithms. The input
could be a series of records like:

a,    b,           c
1,  blue,        true
0,  white,      true
3,  red,         false

where "a" and "b" are condition attributes and "c" is the decision
attribute. The output could be a series of rules that predict "c" based
on the values of "a" and "b."

Also, does anybody know of any temporal dataset with a format similar to
the above? I mean a sequence of observations of a number of variables,
preferably at regular intervals, over a certain period of time.

Any help is appreciated!
