  abstract =     "This article illustrates an artificial developmental
                 system that is a computationally efficient technique
                 for the automatic generation of complex artificial
                 neural networks (ANNs). The artificial developmental
                 system can develop a graph grammar into a modular ANN
                 made of a combination of simpler subnetworks. A genetic
                 algorithm is used to evolve coded grammars that
                 generate ANNs for controlling six-legged robot
                 locomotion. A mechanism for the automatic definition of
                 neural subnetworks is incorporated. Using this
                 mechanism, the genetic algorithm can automatically
                 decompose a problem into subproblems, generate a subANN
                 for solving the subproblem, and instantiate copies of
                 this subANN to build a higher-level ANN that solves the
                 problem. We report some simulation results showing that
                 the same problem cannot be solved if the mechanism for
                 automatic definition of subnetworks is suppressed. We
                 support our argument with pictures that describe the
                 steps of development, how ANN structures are evolved,
                 and how the ANNs compute.",
