Evolution programs evolved

Abstract. Growth grammars in the form of parallel rewrite systems (Lsystems) are used to model morphogenetic processes of plant structures. With the help of evolutionary programming techniques developmental programs are bred which encode plants that exhibit characteristic growth patterns advantageous in competitive environments. Program evolution is demonstrated on the basis of extended genetic programming on symbolic expressions with genetic operators and expression generation strongly relying on templates and pattern matching. 1 Introduction: Wh
