Coevolution of relationship and interaction in cooperative dynamical multiplex networks

Chaos An Interdisciplinary Journal of Nonlinear Science, Год журнала: 2024, Номер 34(2)

Опубликована: Фев. 1, 2024

While actors in a population can interact with anyone else freely, social relations significantly influence our inclination toward particular individuals. The consequence of such interactions, however, may also form the intensity established earlier. These dynamical processes are captured via coevolutionary model staged multiplex networks two distinct layers. In so-called relationship layer, weights edges among players change time as games played alternative interaction layer. As an reasonable assumption, bilateral cooperation confirms while mutual defection weakens these weight factors. Importantly, fitness player, which basically determines success strategy imitation, depends not only on payoff collected from but individual index calculated mentioned factors related edges. Within framework weak prisoner’s dilemma situation, we explore potential outcomes process where assume different topologies for We find that higher average degree graph is more beneficial to maintain regular graphs, randomness links could be decisive factor harsh situations. Surprisingly, stronger coupling between and discourage evolution by weakening direct change. To complete study, monitor how distribution vary detect strong relation its polarization general level.

Evolution of cooperation with asymmetric social interactions

Proceedings of the National Academy of Sciences, Год журнала: 2021, Номер 119(1)

Significance Humans have a remarkable, but not ubiquitous, tendency toward altruism. This behavior reflects classic enigma in evolutionary theory: When and why would individuals forgo selfish interests to help strangers? Population structure is known catalyze cooperation because it enables local reciprocity—I you, you me. But this explanation assumes bidirectional social interactions, whereas human interactions are often unidirectional: One individual has the opportunity contribute altruistically another, conversely. Here we uncover surprising result, that directionality can actually facilitate cooperation. We study effect theoretically also empirical networks. suggest several practical implications, including how modify directions of promote

Adaptive Reputation Promotes Trust in Social Networks

IEEE Transactions on Network Science and Engineering, Год журнала: 2021, Номер 8(4), С. 3087 - 3098

Trust has played a pivotal role in the evolution of modern human societies, and it continues to be an essential underpinning our social interactions. It is therefore important that we develop rigorous mathematical foundations will enable us better understand what promotes erodes trust how best preserve trustworthiness. To effect here propose game, wherein investors, trustworthy trustees, untrustworthy trustees compete for assets subject third-party evaluation system oversees modifies each individual reputation. We use Monte Carlo simulations on networks determine critical values degree rationality reputation threshold warrant high levels wealth. show if investors have access scores fraction drops only sufficiently large, this irrespective determines cutoff untrustworthiness. But even though are allowed irrational investments, can still proliferate high. Our results thus formalize mechanisms networks, which also outline policies diminish untrustworthiness employed real life.

Optimization of institutional incentives for cooperation in structured populations

Journal of The Royal Society Interface, Год журнала: 2023, Номер 20(199)

Опубликована: Фев. 1, 2023

The application of incentives, such as reward and punishment, is a frequently applied way for promoting cooperation among interacting individuals in structured populations. However, how to properly use the incentives still challenging problem incentive-providing institutions. In particular, since implementation incentive costly, explore optimal protocol, which ensures desired collective goal at minimal cost, worthy study. this work, we consider positive negative population whose conflicting interactions are characterized by Prisoner's Dilemma game. We establish an index function quantifying cumulative cost during process implementation, theoretically derive protocols on regular networks. find that both types identical time-invariant. Moreover, compare rewarding punishing schemes concerning provide rigorous basis usage game-theoretical framework. further perform computer simulations support our theoretical results their robustness different structures, including regular, random, small-world scale-free
