Mixed strategy and coevolution dynamics in social networks
Zhong, Weicai; Abbass, Hussein A.; Bender, Axel; Liu, Jing - In: Physica A: Statistical Mechanics and its Applications 390 (2011) 2, pp. 410-417
We investigate coevolution dynamics of both individual strategies and social ties as they adapt within the snowdrift game with mixed strategies. We propose a partner selection mechanism based on the concept of trust. Here trust is considered an instrument for an individual both selecting the...

Cooperative networks overcoming defectors by social influence
Gomez Portillo, Ignacio - In: Physica A: Statistical Mechanics and its Applications 394 (2014) C, pp. 198-210
We address the cooperation problem in structured populations by considering the prisoner’s dilemma game as a metaphor …. In this way, we conclude that in a structured system formed by a growing process, the cooperation evolves if the … theoretical solution of the cooperation problem among genetically unrelated individuals. …

Optimization-based structure identification of dynamical networks
He, Tao; Lu, Xiliang; Wu, Xiaoqun; Lu, Jun-an; Zheng, … - In: Physica A: Statistical Mechanics and its Applications 392 (2013) 4, pp. 1038-1049
The topological structure of a dynamical network plays a pivotal part in its properties, dynamics and control. Thus, understanding and modeling the structure of a network will lead to a better knowledge of its evolutionary mechanisms and to a better cottoning on its dynamical and functional...

Robust adaptive synchronization of dynamical networks via scalar controllers
Li, Zhi; Suh, Il Hong - In: Physica A: Statistical Mechanics and its Applications 388 (2009) 12, pp. 2526-2534
Based on high gain feedback control theory, robust adaptive synchronization of dynamical network is investigated in this paper. When the non-linear coupling functions are unknown but with unknown bounded, some fairly simple robust adaptive scalar feedback controllers are derived. The key idea is...

Exponential synchronization of nonlinear coupled dynamical networks with a delayed coupling
Liu, Xiwei; Chen, Tianping - In: Physica A: Statistical Mechanics and its Applications 381 (2007) C, pp. 82-92
In this paper, we discuss exponential synchronization of nonlinear coupled dynamical networks with a delayed coupling. Sufficient conditions for both delay-independent and delay-dependent global exponential synchronization are obtained based on Lyapunov functional method. It is shown that, for...

A (reactive) lattice-gas approach to economic cycles
Ausloos, Marcel; Clippe, Paulette; Miśkiewicz, Janusz; … - In: Physica A: Statistical Mechanics and its Applications 344 (2004) 1, pp. 1-7
A microscopic approach to macroeconomic features is intended. A model for macroeconomic behavior under heterogeneous spatial economic conditions is reviewed. A birth–death lattice gas model taking into account the influence of an economic environment on the fitness and concentration evolution...

Evolution of economic entities under heterogeneous political/environmental conditions within a Bak–Sneppen-like dynamics
Ausloos, Marcel; Clippe, Paulette; Pȩkalski, Andrzej - In: Physica A: Statistical Mechanics and its Applications 332 (2004) C, pp. 394-402
A model for economic behavior, under heterogeneous spatial economic conditions is developed. The role of selection pressure in a Bak–Sneppen-like dynamics with entity diffusion on a lattice is studied by Monte-Carlo simulation taking into account business rule(s), like enterprise–enterprise...

The coevolution of individual economic characteristics and socioeconomic networks
Stauffer, Dietrich; Hohnisch, Martin; Pittnauer, Sabine - In: Physica A: Statistical Mechanics and its Applications 370 (2006) 2, pp. 734-740
The dynamics of individual characteristics of economic agents is modeled with the link structure influenced by this dynamics: links between agents with similar characteristics are more stable than those between agents with vastly different characteristics. A simple scaling law describes the...

Coevolution with weights of names in structured language games
Lei, Chuang; Jia, Jianyuan; Wu, Te; Wang, Long - In: Physica A: Statistical Mechanics and its Applications 389 (2010) 24, pp. 5628-5634
We propose a coevolutionary version to investigate the naming game, a model recently introduced to describe how shared vocabulary can emerge and persist spontaneously in communication systems. We base our model on the fact that more popular names have more opportunities to be selected by agents...
