Both cooperation and migration are ubiquitous in human society animal world. In this Rapid Communication, we propose an aspiration-induced which individuals will migrate to new sites provided that their payoffs below some aspiration level. It is found moderate level can best favor cooperative behavior. particular, enables cooperator clusters maintain expand whereas induces defector disintegrate, thus promoting the diffusion of among population. Our results provide insights into understanding...

We propose a strategy for achieving maximum cooperation in evolutionary games on complex networks. Each individual is assigned weight that proportional to the power of its degree, where exponent $\ensuremath{\alpha}$ an adjustable parameter controls level diversity among individuals network. During evolution, every chooses one neighbors as reference with probability neighbor, and updates depending their payoff difference. It found there exists optimal value $\ensuremath{\alpha}$, which...

In this letter, we introduce an aspiration-induced reconnection mechanism into the spatial public-goods game. A player will reconnect to a randomly chosen if its payoff acquired from group centered on neighbor does not exceed aspiration level. We find that intermediate level can promote cooperation best. This optimal phenomenon be explained by negative feedback effect, namely, is able result in weak peak of reconnection, which effectively change downfall cooperators and facilitate fast...

We study how the clustering coefficient influences evolution of cooperation in scale-free public goods games. In games played by groups individuals, triangle loops provide stronger support for mutual to resist invasion selfish behavior than that absence such loops, so diffusion cooperative is relatively promoted. The feedback reciprocity mechanism plays a key role facilitating high clustered networks.

An open problem in evolutionary game dynamics is to understand the effect of peer pressure on cooperation a quantitative manner. Peer can be modeled by punishment, which has been proved an effective mechanism sustain among selfish individuals. We investigate symmetric punishment strategy, individual will punish each neighbor if their strategies are different, and vice versa. Because symmetry imposing one might intuitively expect strategy have little cooperation. Utilizing prisoner's dilemma...

We analyze the behavior of Ethernet in networks with a small number active stations, and describe what is known as capture effect. Where station transmits consecutive packets exclusively for prolonged period despite other stations contending access. The effect causes transient unfairness, which results substantial performance degradation. report measurements using TCP/IP that show A solution proposed effectively overcomes algorithm, we call avoidance binary exponential backoff (CABEB), uses...

We propose a variant of the voter model by introducing social diversity in evolution process. Each individual is assigned weight that proportional to power its degree, where exponent $\ensuremath{\alpha}$ an adjustable parameter controls level among individuals network. At each time step, pair connected individuals, say $i$ and $j$, are randomly selected update their opinions. The probability ${p}_{i}$ choosing $i$s opinion as common weight. consider scale-free topology concentrate on...

Despite extensive work on traffic dynamics and epidemic spreading complex networks, the interplay between these two types of dynamical processes has not received adequate attention. We study effect local-routing-based spreading. For case unbounded node-delivery capacity, where is free congestion, we obtain analytic numerical results indicating that threshold can be maximized by an optimal routing protocol. This means effectively controlled local dynamics. bounded delivery qualitative...

Most existing works on transportation dynamics focus networks of a fixed structure, but whose nodes are mobile have become widespread, such as cell-phone networks. We introduce model to explore the basic physics Of particular interest dependence throughput speed agent movement and communication range. Our computations reveal hierarchical for former while, latter, we find an algebraic power law between range with exponent determined by speed. develop physical theory based Fokker-Planck...

We study a system of self-propelled agents with the restricted vision. The field vision each agent is only sector disk bounded by two radii and included arc. inclination these characterized view angle. consideration closer to reality because natural swarms usually do not have panoramic view. Interestingly, we find that there exists an optimal angle, leading fastest direction consensus. value angle depends on density, interaction radius, absolute velocity swarms, strength noise. Our findings...

The paradox of cooperation among selfish individuals still puzzles scientific communities. Although a large amount evidence has demonstrated that the cooperator clusters in spatial games are effective protecting cooperators against invasion defectors, we continue to lack condition for formation giant cluster ensures prevalence system. Here, study dynamical organization prisoner's dilemma game offer dominance cooperation, finding phase transition characterized by emergence spanning occurs...

Recent empirical studies suggest that heavy-tailed distributions of human activities are universal in real social dynamics [Muchnik, \emph{et al.}, Sci. Rep. \textbf{3}, 1783 (2013)]. On the other hand, community structure is ubiquitous biological and networks [M.~E.~J. Newman, Nat. Phys. \textbf{8}, 25 (2012)]. Motivated by these facts, we here consider evolutionary Prisoner's dilemma game taking place on top a network to investigate how heterogeneity activity individuals affect evolution...
