We consider models of growing multilevel systems wherein the growth process is driven by rules of tournament selection. A system can be conceived as an evolving tree with a new node being attached to a contestant node at the best hierarchy level (a level nearest to the tree root). The proposed evolution reflects limited information on system properties available to new nodes. It can also be expressed in terms of population dynamics. Two models are considered: a constant tournament (CT) model… 

Models of random graph hierarchies

It is found that in both models the number of nodes at a given hierarchy level h decreases approximately exponentially with h, and the height of the hierarchy H decreases monotonically with the connectivity parameter c in the RGH model and it reaches a maximum for a certain cmax in the LRGH model.

Coevolution of information processing and topology in hierarchical adaptive random Boolean networks

This work proposes a hierarchical adaptive random Boolean Network (HARBN) as a system consisting of distinct adaptive RBNs (ARBNs) – subnetworks – connected by a set of permanent interlinks, and investigates mean node information, mean edge information as well as mean node degree.

Information theory and maximum entropy principles in non-equilibrium statistical physics

This thesis reconsiders key assumptions underlying kinetic theory of gases from the perspective of information theory, aiming in particular at generalizing Boltzmann's molecular chaos hypothesis.
