(strong) Causality

property of a system, that small variations in the cause only provoke small variations in the effect. In EAs variations of the cause correspond to changes of the genotype and variations of the effect to changes of the phenotype or of the respective objective function value (fitness). Although strong causality remarkably increases the efficiency of EAs, it is not always a prerequisite for their successful application.
