I think you need to elaborate on your needs/requirements to get any substantial help. 

Yes, as Mr. Mellin suggests - rule-based classification of what? There are many metaheuristic algorithms, and they may need to be adapted to the problem being solved. For example, in forestry we often deal with integer decision variables and spatial (related to land, and non-linear) constraints. Some of the basic metaheuristics need to be modified to handle these issues.

Thanks Jonas Mellin and Pete Bettinger. Actually, metaheuristics have been used for rule mining to solve classification problems - just like the one mentioned below. I have already gone through the methodology mentioned in such few papers, but I need some implementation code to strengthen my understanding of the mater. Hope it clarifies my concerns.
