CERUTO-CORDOVES*, Taymi; LAPEIRA-MENA, Orenia; ROSETE-SUAREZ, Alejandro  y  ESPIN-ANDRADE, Rafael. Comparison of metaheuristics for obtaining fuzzy predicates: a curious case. Rev cuba cienc informat [online]. 2014, vol.8, n.2, pp.69-84. ISSN 2227-1899.

This paper presents acomparative study of threemetaheuristicson the problem of obtaining fuzzy predicateswithhigh truth value. According to theNo Free LunchTheorem(NFL) cannotestablishanygeneral superiority of any metaheuristic over the others. This work demonstrates thateven within the sametype of problemcanbe difficult to establishthe superiority of ametaheuristic. In this case, eachmetaheuristicis the bestat leastinone of the fourvariantsoffuzzy operatoremployedand normal formof the obtained predicate. This curiouscasereveals the importance oftheexperimentalcomparison ofmetaheuristics, before assuming thesuperiority of oneover the other.

Palabras clave : Metaheuristic; fuzzy logic operators; normal forms; fuzzy predicates.
