  abstract =     "This paper compares two grammar based Evolutionary
                 Automatic Programming methods, Grammatical Evolution
                 (GE) and Chorus. Both systems evolve sequences of
                 derivation rules which can be used to produce computer
                 programs, however, Chorus employs a position
                 independent representation, while GE uses polymorphic
                 codons, the meaning of which depends on the context in
                 which they are used.

                 We consider issues such as the order in which rules
                 appear in individuals, and demonstrate that an order
                 always emerges with Chorus, which is similar to that of
                 GE, but more flexible.

                 The paper also examines the final step of evolution,
                 that is, how perfect individuals are produced, and how
                 they differ from their immediate neighbours.

                 We demonstrate that, although Chorus appears to be more
                 flexible structure-wise, GE tends to produce
                 individuals with a higher neutrality, suggesting that
                 its representation can, in some cases, make finding the
                 perfect solution easier.",
