Skepticism and rumor spreading: the role of spatial correlations
Marco Antonio Amaral, W. G. Dantas, Jeferson J. Arenzon
Critical thinking and skepticism are fundamental mechanisms that one may use to prevent the spreading of rumors, fake-news and misinformation. We consider a simple model in which a…
Strategy equilibrium in dilemma games with off-diagonal payoff perturbations
Marco A. Amaral, Marco A. Javarone
We analyse the strategy equilibrium of dilemma games considering a payoff matrix affected by small and random perturbations on the off-diagonal. Notably, a recent work [1] reported…
Heterogeneity in evolutionary games: an analysis of the risk perception
Marco A. Amaral, Marco A. Javarone
In this work, we analyse the relationship between heterogeneity and cooperation. Previous investigations suggest that this relation is nontrivial, as some authors found that hetero…
Moderate death rates can be beneficial for the evolution of cooperation
Elton Júnior. S, Marco A. Amaral, Lucas Wardil
Spatial structure is one of the simplest and most studied ecological factors that affect the evolution of cooperation. It has been shown that spatial reciprocity promotes cooperati…
Role-separating ordering in social dilemmas controlled by topological frustration
Marco A. Amaral, Matjaz Perc, Lucas Wardil +3
"Three is a crowd" is an old proverb that applies as much to social interactions, as it does to frustrated configurations in statistical physics models. Accordingly, social relatio…
Evolutionary mixed games in structured populations: Cooperation and the benefits of heterogeneity
Marco A. Amaral, Lucas Wardil, Matjaz Perc +1
Evolutionary games on networks traditionally involve the same game at each interaction. Here we depart from this assumption by considering mixed games, where the game played at eac…
