Dear Colleagues,

The invited book chapter on Automatically Defined Functions in GEP is now
available online both in pdf format and html at:

http://www.gene-expression-programming.com/webpapers/abstracts.asp#13

Ferreira, C., Automatically Defined Functions in Gene Expression
Programming. In N. Nedjah, L. de M. Mourelle, A. Abraham, eds., Genetic
Systems Programming: Theory and Experiences, Studies in Computational
Intelligence, Vol. 13, pp. 21-56, Springer-Verlag, 2006.

ABSTRACT: In this chapter it is shown how Automatically Defined Functions
are encoded in the genotype/phenotype system of Gene Expression Programming.
As an introduction, the fundamental differences between Gene Expression
Programming and its predecessors, Genetic Algorithms and Genetic
Programming, are briefly summarized so that the evolutionary advantages of
Gene Expression Programming are better understood. The introduction proceeds
with a detailed description of the architecture of the main players of Gene
Expression Programming (chromosomes and expression trees), focusing mainly
on the interactions between them and how the simple, yet revolutionary,
structure of the chromosomes allows the efficient, unconstrained exploration
of the search space. The work proceeds with an introduction to Automatically
Defined Functions and how they are implemented in Gene Expression
Programming. Furthermore, the importance of Automatically Defined Functions
in Evolutionary Computation is thoroughly analyzed by comparing the
performance of sophisticated learning systems with Automatically Defined
Functions with much simpler ones on the sextic polynomial problem. 

Best wishes,
Candida
