Adaptation and decision making mechanisms of complex networks

Description:

In this project we identified two general mechanisms of the adaptation of complex systems to changes in their environment. Shifts between a.) more plastic and b.) more rigid states (plasticity-rigidity cycles) enable the complex systems and their network representations a.) to explore a wide range of potential responses, or b.) to select the optimal response, respectively. In case of known situations, system response is often defined by a fast action of well-selected few nodes of the network core. On the contrary, in unknown situations a multitude of peripheral nodes are also involved in the slowly emerging community response, the wisdom of crowds. Such a "slow democracy" process may also refine the primary, fast response of core nodes.

We have summarized the above two general adaptation and decision making mechanisms in the following two pre-publications as preliminaries of future papers and a future book.
