INCREASING LENGTH GENOTYPES IN EVOLUTIONARY ELECTRONICS Ricardo Salem Zebulum

We investigate the use of Artificial Evolution with increasing length genotypes in Evolutionary Electronics. We demonstrate the need of using variable size genotypes in Evolutionary Electronics. After giving a brief description of our evolutionary methodology, we present a case study, consisting of the evolution of a combinational function. Finally, we make general observations about the methodology, addressing the problems of controlling the genotypes growth and selecting the genetic material used to increase the chromosomes. 1 Introduction Our work investigates the use of increasing length genotypes in the area of Evolutionary Electronics (Evolelec), which studies applications of Artificial Evolution in the design of electronic circuits. The use of increasing length genotypes seems to be the most natural evolutionary algorithm approach in Evolelec. Nevertheless, many problems arise when we apply this evolutionary approach, such as the genotypes growth control. Moreover, we have to r..
