  abstract =     "Recent research has considered the role of locality in
                 GP representations. We use a modified statistical
                 technique drawn from numerical ecology, the Mantel
                 test, to measure the locality of integer-encoded GP.
                 Weak locality is identified in a case study on
                 Cartesian Genetic Programming (CGP), a directed acyclic
                 graph representation. A method of varying syntactic
                 program locality continuously through the application
                 of a biased mutation operator is demonstrated. The
                 impact of varying locality under the new measure is
                 assessed over a randomly generated set of polynomial
                 symbolic regression problems. We observe that enforcing
                 higher levels of locality in CGP is associated with
                 poorer performance on the problem set and discuss
                 implications in the context of existing models of GP
                 genotype-phenotype maps.",
