  abstract =     "We present Hierarchical Grammatical Evolution (HGE)
                 and its variant Weighted HGE (WHGE), two novel
                 genotype-phenotype mapping procedures to be used in the
                 Grammatical Evolution (GE) framework. HGE/WHGE are
                 designed to exhibit better variational inheritance than
                 standard GE without imposing any constraint on the
                 structure of the genotype nor on the genetic operators.
                 Our proposal considers the phenotype as a hierarchy of
                 non-terminal expansions and is based on two key ideas:
                 (i) the closer the non-terminal to be expanded to the
                 root of the hierarchy the larger the genotype substring
                 determining its expansion, and (ii) upon expansion, a
                 non-terminal divides its genotype sub-string among the
                 resulting non-terminals. We experimentally evaluate our
                 proposals on a set of benchmark problems and show that
                 for the majority of them WHGE outperforms GE (and its
                 variant πGE).",
