Optimal distribution of incentives for public cooperation in heterogeneous interaction environments
Published 2014-07-01“…In the framework of evolutionary games with institutional reciprocity, limited incentives are at disposal for rewarding cooperators and punishing defectors. In the simplest case, it can be assumed that, depending on their strategies, all players receive equal incentives from the common pool. …”

Fast deliberation is related to unconditional behaviour in iterated Prisoners’ Dilemma experiments
Published 2022-11-01“…Consequently, fast decisions do not distinguish cooperators from defectors in these experiments, but appear to separate those that are more reactive to the behaviour of others from those that act categorically.…”

Evolution of cooperation and consistent personalities in public goods games
Published 2021-12-01“…I consider two different scenarios where either only first-round cooperators play a second public goods game, or both first-round cooperators and first-round defectors play a second public goods game, but in different groups. …”

Reactive Oxygen and Sulfur Species: Partners in Crime
Published 2022-10-01“…The emergence of complexity requires cooperation, yet selection typically favors defectors that do not cooperate. Such evolutionary conflict can be alleviated by a variety of mechanisms, allowing complexity to emerge. …”

“IS Drew This Dream Picture—Like Floating on a Pink Cloud”: Danish Returnees’ Entry into and Exit from Salafi-Jihadism through Nurtured and Fractured Fantasies
Published 2022-07-01“…On the basis of qualitative interviews with three Danish Salafi-jihadist defectors (for example, from the Islamic State), this article unravels the connection and disconnection between engagement, disengagement, and resocialization. …”

Suffering makes you egoist: acute pain increases acceptance rates and reduces fairness during a bilateral ultimatum game.

Relational diversity promotes cooperation in prisoner's dilemma games.
Published 2014-01-01“…We proved that the facilitation of the cooperative strategy relies mostly on the cooperative allies between best friends, resulting in the formation of cooperative clusters which are able to prevail against the defectors even when there is a large cost to cooperate. …”

Environment-based preference selection promotes cooperation in spatial prisoner’s dilemma game
Published 2018-10-01“…Through numerous computing simulations, we find that environment-based preference selection, which accelerates the microscopic organization of cooperator clusters to resist the aggression of defectors, can truly promote cooperation within a large range of parameters. …”

Evolutionary dynamics of general group interactions in structured populations
Published 2016“…Here population structure sometimes inhibits cooperation for the threshold public goods game, where depending on the benefit to cost ratio, the outcomes are bistability or a monomorphic population of defectors or cooperators. Our results suggest, counterintuitively, that structured populations are not always beneficial for the evolution of cooperation for nonlinear group interactions.…”

Range expansion promotes cooperation in an experimental microbial metapopulation
Published 2013“…We found that range expansions favor the maintenance of cooperation in two ways: (i) through the enrichment of cooperators at the front of the expanding population and (ii) by allowing cooperators to “outrun” an invading wave of defectors. In this system, cooperation is enhanced through the coupling of population ecology and evolutionary dynamics in expanding populations, thus providing experimental evidence for a unique mechanism through which cooperative behaviors could be maintained in nature.…”

When agreement-accepting free-riders are a necessary evil for the evolution of cooperation

A Comparative Study of Commit Representations for JIT Vulnerability Prediction
Published 2024-01-01“…For training and evaluation, we used two recently published datasets containing vulnerability-inducing commits: ProjectKB and Defectors. Our results highlight the trade-offs between predictive accuracy and operational flexibility and also provide guidance on the use of ML-based automation for developers, especially considering false positive rates in commit-based vulnerability prediction. …”

Partial privatization and cooperation in biofilms
Published 2023-12-01“…Abstract The evolution of cooperation in microbes is a challenge to explain because microbes producing costly goods for the benefit of any strain types (cooperators) often withstand the threat of elimination by interacting with individuals that exploit these benefits without contributing (defectors). Here we developed an individual-based model to investigate whether partial privatization via the partial secretion of goods can favor cooperation in structured, surface-attaching microbial populations, biofilms. …”

Ancestral social environments plus nonlinear benefits can explain cooperation in human societies
