  abstract =     "The relation between diversity and genotype to
                 phenotype mapping has been the focus of several
                 studies. In those Evolutionary Algorithms (EAs) where
                 the genotype is a sequence of symbols, the contribution
                 of each of those symbols in determining the phenotype
                 may vary greatly possibly being null. In the latter
                 case, the unused portions of the genotype may host a
                 large amount of the population diversity. However,
                 reasoning on coarse-grained measures makes it hard to
                 validate such a claim and, more in general, to gain
                 insights into the interactions between
                 genotype-phenotype mapping and diversity. In this
                 paper, we propose a novel visualization which
                 summarizes in a single, compact heat map (the DU map),
                 three kinds of information: (a) how diverse are the
                 genotypes in the population at the level of single
                 symbols; (b) if and to what degree each individual
                 symbol in the genotype contributes to the phenotype;
                 (c) how the two previous measures vary during the
                 evolution. We experimentally verify the usefulness of
                 the DU map w.r.t. its primary goal and, more broadly,
                 when used to analyse different EA design options. We
                 apply it to Grammatical Evolution (GE) as it
                 constitutes an ideal test bed for the DU map, due to
                 the availability of different mapping functions.",
