Interaction in agent-based economics: A survey on the network approach

Bargigli, Leonardo; Tedeschi, Gabriele - In: Physica A: Statistical Mechanics and its Applications 399 (2014) C, pp. 1-15

In this paper we aim to introduce the reader to some basic concepts and instruments used in a wide range of economic networks models. In particular, we adopt the theory of random networks as the main tool to describe the relationship between the organization of interaction among individuals...

Monte Carlo investigation of anomalous transport in presence of a discontinuity and of an advection field

Marseguerra, M.; Zoia, A. - In: Physica A: Statistical Mechanics and its Applications 377 (2007) 2, pp. 448-464

Anomalous diffusion has recently turned out to be almost ubiquitous in transport problems. When the physical properties of the medium where the transport process takes place are stationary and constant at each spatial location, anomalous transport has been successfully analysed within the...

Relations between average distance, heterogeneity and network synchronizability

Zhao, Ming; Zhou, Tao; Wang, Bing-Hong; Yan, Gang; … - In: Physica A: Statistical Mechanics and its Applications 371 (2006) 2, pp. 773-780

By using the random interchanging algorithm, we investigate the relations between average distance, standard deviation of degree distribution and synchronizability of complex networks. We find that both increasing the average distance and magnifying the degree deviation will make the network...

Balancing the competing demands of harvesting and safety from predation: Lévy walk searches outperform composite Brownian walk searches but only when foraging under the risk of predation

Reynolds, A.M. - In: Physica A: Statistical Mechanics and its Applications 389 (2010) 21, pp. 4740-4746

Some foragers have movement patterns that can be approximated by Lévy walks whilst others may be better represented as composite Brownian walks. Many attempts have been made to interpret these movement patterns in terms of optimal searching strategies for the location of randomly and sparsely...

density and heterogeneity in degree distribution. In this work, it will be shown that synchronizability of Type I networks is … independent of heterogeneity in the degree distribution when the link density is smaller than 0.02. Synchronizability and link … density are proportional. When the link density is larger than 0.025, heterogeneity decides the curve slope. The …
