Description

The term "Complex Systems" is commonly used to describe the collective behavior of a huge ensemble of interacting elements. While the rules governing the interactions of the elements might be relatively simple, a rich non-linear behavior at the coarse-grained systems' level often arises. For the systematic analysis and deeper understanding of such complex responses, one of the most critical issues revolves around the bridging of the different scales: the micro-scale, where the interactions of the system’s units take place and that of the macroscopic scale where the coarse-grained dynamic behavior emerges. Using the Equation-Free approach, a novel computational framework for multiscale analysis, it will be presented how one can extract, in a computational strict and systematic way, the emergent dynamical attributes from detailed large-scale microscopic/agent-based model. A useful note on the effects of the heterogeneous network structures on the emergent dynamics of complex systems will also be presented bringing to surface the need for further understanding of the interplay between the emergent dynamics and the underlying interaction network.
