Complex systems: Network thinking

摘要

In this article, I discuss some recent ideas in complex systems on the topic of networks, contained in or inspired by three recent complex systems books. The general science of networks is the subject of Albert-Lazlo Barabási's Linked [A.-L. Barabási, Linked: The New Science of Networks, Perseus, New York, 2002] and Duncan Watts' Six Degrees [D. Watts, Six Degrees: The Science of a Connected Age, Gardner's Books, New York, 2003]. Commonalities among complex biological networks, e.g., immune systems, social insects, and cellular metabolism, and their relation to intelligence in computational systems are explored in the proceedings of a interdisciplinary conference on “Distributed Autonomous Systems” [L.A. Segel, I.R. Cohen (Eds.), Design Principles for the Immune System and Other Distributed Autonomous Systems, Oxford University Press, New York, 2001].
