Figures and Tables from this paper

Evolution of egoism on semi-directed and undirected Barabási-Albert networks

TLDR
The authors' simulations showed that egoism wins, differently from other results found in the literature where ethnocentric strategy is common, here, mechanisms such as reciprocity are absent.

Evolution of tag-based cooperation with emotion on complex networks

TLDR
The authors' simulations showed that egoism and altruism win, differently from other results found in the literature where ethnocentric strategy is common.

Evolution of tag-based cooperation on Erdős–Rényi random graphs

TLDR
These findings highlight conditions under which ethnocentrism is less stable or suppressed by other competing strategies, and find surprisingly regular oscillations which are not damped in the course of time even after half a million Monte Carlo steps.

Pitfalls in Spatial Modelling of Ethnocentrism: A Simulation Analysis of the Model of Hammond and Axelrod

TLDR
It will be shown that agents with an ingroup bias are successful compared to unconditional co-operators since they only exclude non-clones, but are outcompeted by less error-prone kin identifiers, and the results of the simulations can be explained by a simple form of kin selection.

The Evolutionary Dominance of Ethnocentric Cooperation

TLDR
It is shown that ethnocentrism eventually overcomes its closest competitor, humanitarianism, by exploiting humanitarian cooperation across group boundaries as world population saturates, including early stages of humanitarian dominance.

Ethnocentrism refers to the tendency to behave differently towards strangers based only on whether they belong to the ingroup or the outgroup. It is a widespread phenomenon that can be triggered by

Benefits of memory for the evolution of tag-based cooperation in structured populations

TLDR
It is found that the previously reported decline of cooperation in memory-based models, typically observed at a high memory capacity, is now prevented with the help of tags, suggesting that the evolutionary advantages of memory capacity limits may be far more complex than previously assumed.

The Evolution of Ethnocentrism

Ethnocentrism is a nearly universal syndrome of attitudes and behaviors, typically including in-group favoritism. Empirical evidence suggests that a predisposition to favor in-groups can be easily

Agent‐based Computer Simulations of Language Choice Dynamics

TLDR
The findings uncover some of the unique properties of opinion formation in social groups when the process is affected by asymmetric noise distribution, unstable intergroup boundaries, and different migratory behaviors.

A new route to the evolution of cooperation

TLDR
It is shown that cooperators are capable of exploring the heterogeneity of the population structure to become evolutionary competitive and cooperation becomes the dominating trait in scale‐free networks of contacts in which the few highly connected individuals are directly inter‐connected, in this way contributing to self‐sustain cooperation.

MAJORITY-VOTE ON DIRECTED BARABÁSI–ALBERT NETWORKS

On directed Barabasi–Albert networks with two and seven neighbours selected by each added site, the Ising model was seen not to show a spontaneous magnetisation. Instead, the decay time for flipping

Evolutionary dynamics of social dilemmas in structured heterogeneous populations.

TLDR
It is shown that, for all dilemmas, increasing heterogeneity favors the emergence of cooperation, such that long-term cooperative behavior easily resists short-term noncooperative behavior.

Evolution of cooperation without reciprocity

TLDR
Computer simulations are used to show that cooperation can arise when agents donate to others who are sufficiently similar to themselves in some arbitrary characteristic, or ‘tag’, which can be a marking, display, or other observable trait.

SIMULATION OF MAJORITY RULE DISTURBED BY POWER-LAW NOISE ON DIRECTED AND UNDIRECTED BARABÁSI–ALBERT NETWORKS

TLDR
On directed and undirected Barabasi–Albert networks the Ising model with spin S = 1/2 in the presence of a kind of noise is now studied through Monte Carlo simulations and the noise spectrum P(n) is introduced to mimic the self-organized criticality as a model influence of a complex environment.

Cooperation, social networks, and the emergence of leadership in a prisoner's dilemma with adaptive local interactions.

TLDR
It is shown how the network adaptation dynamics favors the emergence of cooperators with the highest payoff, and these "leaders" are shown to sustain the global cooperative steady state.
