Structure properties of evolutionary spatially embedded networks

Hui, Z.; Li, W.; Cai, X.; Greneche, J.M.; Wang, Q.A. - In: Physica A: Statistical Mechanics and its Applications 392 (2013) 8, pp. 1909-1919

This work is a modeling of evolutionary networks embedded in one or two dimensional configuration space. The evolution is based on two attachments depending on degree and spatial distance. The probability for a new node n to connect with a previous node i at distance rni follows...

Comparing an Individual-Based Model of Behaviour Diffusion with Its Mean Field Aggregate Approximation

Edwards, Margaret; Huet, Sylvie; Goreaud, François; … - In: Journal of Artificial Societies and Social Simulation 6 (2003) 4, pp. 9-9

In this paper we compare a version of the individual-based â€œthreshold modelâ€ of innovation diffusion (Valente 95) with an aggregate deterministic model that we constructed from it. The classical threshold model supposes that an individual adopts a behaviour according to a trade-off...

life-history assumptions. Mean-field approximation fails to predict the outcome of computer simulations. Pair approximation … analyse the dynamics depending on major parameters. Mathematical analyses based on invasion probability analysis, mean-field … approximation, as well as pair approximation are also used. We find that the lattice structure promotes the evolution of cooperation …

Centralized versus decentralized control—A solvable stylized model in transportation

Hongler, Max-Olivier; Gallay, Olivier; Hülsmann, Michael; … - In: Physica A: Statistical Mechanics and its Applications 389 (2010) 19, pp. 4162-4171

Today’s supply networks consist of a certain amount of logistics objects that are enabled to interact with each other and to decide autonomously upon their next steps; in other words, they exhibit a certain degree of autonomous cooperation. Therefore, modern logistics research regards them as...
