abstract = "In this paper, I describe how to use Grammatical
Evolution to implement a parametrised Lindenmayer
System (L-System), where the number of production rules
of the L-System is determined by the genome of the
individual, rather than being determined by the user
before hand. This leaves the number of production rules
as a free parameter and allows the underlying topology
of the system to be optimised by the evolutionary
algorithm.",
