  abstract =     "Understanding the relationship between selection,
                 genotype-phenotype map and loss of population diversity
                 represents an important step towards more effective
                 genetic programming (GP) algorithms. This paper
                 describes an approach to capture dynamic changes in
                 this relationship. We analyse the frequency
                 distribution of points in the diversity plane defined
                 by structural and semantic similarity measures. We test
                 our methodology using standard GP (SGP) on a number of
                 test problems, as well as Offspring Selection GP
                 (OS-GP), an algorithmic flavour where selection is
                 explicitly focused towards adaptive change. We end with
                 a discussion about the implications of diversity
                 maintenance for each of the tested algorithms. We
                 conclude that diversity needs to be considered in the
                 context of fitness improvement, and that more diversity
                 is not necessarily beneficial in terms of solution
