Open-ended evolution to discover analogue circuits for beyond conventional applications

This paper presents a novel solution method combining classical genetic algorithm, substructure reuse and incremental evolution to a well-known problem in EHW community. The method was implemented using C++ and PSpice, as requested by Creative Machines Lab, Cornell University, USA. The approach is based on simulation of analogue circuit for a given graphically described signal. If the problem can be slightly rephrased as the analysis of sound waves for pitch identification, this approach can be successfully applied to completely new problem domains. This work led to an on-going three-year project on Sound Recognition fully sponsored by Scientific-Technical Centre REB, Kazakhstan.
