Andre, David 1997 Evolution of tri-state Frequency Discriminator for the Source Identification Problem using Genetic Programming Paul P. Wang International Conference of Information Sciences 1 95--99 genetic algorithms, genetic programming Automated synthesis of analog electronic circuits is recognized as a difficult problem. Genetic programming was used to evolve both the topology and the sizing (numerical values) for each component of a circuit that can perform source identification by correctly classify an incoming signal into categories. http://www.genetic-programming.com/jkpdf/fea1997.pdf
