We propose a new type of multi-population GA, that is the p-fGA (Phenotypic Forking GA), an extension of the previously proposed g-fGA (Genotype Forking GA). We use multi-population schemes ; this includes one parent population with a blocking mode and one or more child populations with a shrinking mode. In the g-fGA, sub-space for each population is defined by the salient schema within the genotypic search space. In contrast to this, the p-fGA defines its sub-space by the neighborhood hypercube around the current best individual in the phenotypic search space. The empirical results show that the p-fGA has a good performance as well as the g-fGA, and the variable resolution p-fGA has a capability of searching with high resolution and can improve the local searching capability in a genetic search.
