The success of Evolutionary Algorithms (EAs) on a wide range of 
otherwise intractable problems has promoted its use. As EAs are 
applied to increasingly difficult problems that require increasingly 
complex solutions, they face a number of problems: premature convergence 
to suboptimal solutions, stagnation of search in large search spaces, 
negative epistatic effects, disruption of large building blocks, and 
scalability, among others. Nature evolves instructions in the form of 
genes that are used to specify the construction of organisms using a 
highly non-linear process: development. 
Self-organization is fundamental to the developmental process at all 
levels: molecular, genetic, and cellular. With new reports of the 
number of genes in the human genome being revised downwards, the role 
of self-organization in complex webs of gene regulation is all the 
more salient. Given these new findings, perhaps the self-organization 
of genotypic instructions that transform genotype to phenotype is a 
key missing ingredient necessary for unleashing the evolution of complex 
and scalable solutions with emergent phenomena such as: scale-free-ness, 
adaptability, innovation, evolvability, and robustness. This workshop will 
focus on domain-independent methods for representing complex solutions 
with self-organizable building blocks, and on developmental principles 
for specifying the construction of complex systems. This workshop welcomes 
submissions from computer science and engineering, as well as from 
biologists on relevant topics that may help shed light on self-organizing 
principles for evolutionary computation.

Topics of interest include:

* Models of complexity building using self-organization
* Emergent behavior in representations
* Methods of design and evaluation of self-organizable representational 
  building blocks
* Scalability of self-organizational processes to high complexities
* Self-organization theoretical approaches: complexity, chaos, synergetics, 
  self-organized criticality, non-equilibrium thermodynamics, etc.
* Self-organized development
* Genotype-phenotype mappings for self-organization and single & multicellular 
* Pattern formation, morphogenesis, cellular differentiation, and growth
* Models of genetic regulatory networks, modularity, segmentation, and 
* Scalability & Evolvability of developmental processes
* Robustness, self-repair and regeneration in developmental processes
* Real world applications of developmental principles

Workshop Format: 

This workshop seeks to bring together researchers from diverse problem domains 
to informally discuss issues related to the representation of complex solutions 
using self-organization of simple building blocks for evolutionary algorithms 
in particular, and the issue of building complexity from simplicity in general. 
We welcome technical papers describing completed or on-going research as well 
as position papers outlining current research issues, approaches or research 
agendas. We also welcome suggestions to panel discussions. Preprints will be 
circulated by email prior to the meeting. 

Workshop Submission Instructions:

The style of the paper should follow the GECCO 2005 Workshops guidelines. 
Authors are requested to submit their papers in electronic form (postscript 
or PDF) via email to: igaribay at cs.ucf.edu. Accepted papers will be published 
in the GECCO-2005 CD-ROM.
