Evolutionary design of complex functional networks

Abstract:
Complex biological networks are responsible for many fundamental processes in living organisms, including signal transduction and genetic expression in biological cells and signal processing in neural networks. These functional networks, a product of the evolution, are characterized by their robustness against damages, mutations and noise. Functionality and robustness are reflected in their architectures which exhibit structures different from random networks and lattices.
To design functional networks, robust against local damages and noise, and to study, how the requirements of functionality and robustness are reflected in their architecture, are the objectives of this work. Remarkable differences between architectures of the designed networks, depending on the criteria of robustness imposed during their construction, are observed. Particularly, motif distributions of these networks are different. Comparing them with real biological networks, we have found that the networks robust against deletion of links show motif distributions which are very similar to those of some neural systems and to the development transcription and signal transduction networks of biological macroorganisms.
