Abstract

Evolutionary mechanisms as observed in nature are successfully used in evo- lutionary algorithms (EA) in order to solve complex optimization tasks or to mimick natural evolution processes. We present a collection of evolutionary algorithms which we have implemented in Mathematica together with some visualization examples and applications. The three major EA-classes are dis- cussed: Evolution Strategies (ES), Genetic Algorithms (GA), and Genetic Programming (GP). Interactive evolution is demonstrated by the breeding of biomorphs, recursively branched line drawings. Multi-modal ES- and GA- experiments are demonstrated for a parameter optimization task. The evolu- tion of robot control programs shows a simple GP-application. The article concludes with a more sophisticated GP-example: the breeding o
