Evolution of Natural and Artificial Systems - Metaphors and Analogies in Single and Multi-Objective Problems

(GECCO- ENAS- 2007)


GECCO - 07 Workshop on the Evolution of Natural and Artificial Systems - Metaphors and Analogies in Single and Multi-Objective Problems

(GECCO- ENAS- 2007)

!!! Please note the extended deadline for papers and abstracts as detailed below

Background and Motivation:

The aim of this workshop is to understand the similarities and dissimilarities between biological evolution and computational evolution.

Work on evolutionary computation (EC) has made extensive use of concepts from biology such as the notion of "the fittest" or "optimal" solution to an evolutionary problem. Other concepts from biology such as mutation, speciation, and co-evolution, have also been used in work on EC. There are two complementary views about the utility of analogy between natural and artificial systems. The first view is that the study of natural systems can lead to the development of better artificial systems. The second view is that the study of artificial systems can lead to new insights on the evolution of natural systems. While the former view is commonly accepted, especially in the EC community, the latter view has yet to be fully accepted and explored. Design, planning and analyses of man-made systems often involve the use of Pareto-optimality and the notion of non-dominancy. When studying biological systems these are not easily apparent. Computational tools, such as Multi-objective Evolutionary Algorithms, may be particularly useful in attempts to understand the nature of evolutionary tradeoffs and the degree to which evolution involves a "balance" between selection for multiple objectives.


Understanding of applied metaphors and analogies in EC
New metaphors and analogies in EC
Dissimilarities between natural and artificial evolution
The adaptation/optimization debate and its relation to teleology and the notion of objectives
Tradeoffs in natural systems and how these arise
