	abstract = {Most practical electrical circuits contain modular
                 substructures that are repeatedly used to create the
                 overall circuit. Genetic programming with automatically
                 defined functions and architecture-altering operations
                 successfully evolved a design for a two-band crossover
                 (woofer and tweeter) filter with a crossover frequency
                 of 2,512 Hz. Both the topology and the sizing
                 (numerical values) for each component of a the circuit
                 were evolved. In the evolved circuit, three different
                 electrical substructures were used; one was invoked
                 five times; and one was invoked as part of a hierarchy;
                 and one substructure was invoked with different
                 Numerical arguments so that different numerical
                 component values were assigned to the substructure's
                 components.},
