  abstract =     "One of the main limitations of scalability in
                 body-brain evolution systems is the representation
                 chosen for encoding creatures. This paper defines a
                 class of representations called generative
                 representations, which are identified by their ability
                 to reuse elements of the genotype in the translation to
                 the phenotype. This paper presents an example of a
                 generative representation for the concurrent evolution
                 of the morphology and neural controller of simulated
                 robots, and also introduces GENRE, an evolutionary
                 system for evolving designs using this representation.
                 Applying GENRE to the task of evolving robots for
                 locomotion and comparing it against a non-generative
                 (direct) representation shows that the generative
                 representation system rapidly produces robots with
                 significantly greater fitness. Analyzing these results
                 shows that the generative representation system
                 achieves better performance by capturing useful bias
                 from the design space and by allowing viable large
                 scale mutations in the phenotype. Generative
                 representations thereby enable the encapsulation,
                 coordination, and reuse of assemblies of parts.",
