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. %8 "7-8 " # oct %9 inproceedings %@ 3-540-63173-9
