Abstract:
In their study of artificial intelligence methodologies and specifically of complex systems, Hofstadter and Mitchell over the years established a computational model and a micro-domain that combined lead to high-level perception. Their ideas are showcased in Copycat – a model of mental fluidity and emergent deliberation. Lewis developed a generic framework based on ideas of the Copycat model to be used as a springboard for building complex adaptive systems called Starcat.

This paper discusses the Copycat and Starcat architectures and presents the results of experimenting with the architecture. A toy problem of discovering palindromes in random strings is discussed along with its implementation as a complex system using Starcat. Tests are run to explore various aspects of the framework including pressures, the Slipnet update algorithm and the effect of the Coderack on the computation. Future research suggestions are presented based on the results of the tests.
