Evolutionary Game Theory and Cooperation

The evolution of public goods altruism

The paper develops a model showing that altruistic public goods investment can exclude cheaters unless altruists are overly generous, and local competition prevents stable coexistence.

Emergence of alternative offspring care patterns from the evolution of parental negotiation strategies

This study uses individual-based simulations to show that parental negotiation strategies can lead to four alternative care patterns, including effective cooperation based on tit-for-tat rather than compensation.

The genetical evolution of social preferences: where the categorical imperatives of Hamilton, Kant and Nash meet

The paper models how social preferences evolve genetically, showing that Nash equilibria and inclusive fitness emerge as uninvadable strategies in pairwise interactions.

Spend today or build for tomorrow? Kinship dynamics and the evolution of alternative helping strategies in cooperative breeders.

The paper uses mathematical models to show that kinship dynamics influence whether helpers in cooperative breeders prioritize immediate or durable benefits.

Evolution of objectives can enable prosocial behaviour without social awareness

The paper models how evolving perception functions can lead to prosocial behavior in decentralized systems without social awareness.

From friend to foe and back - Coevolutionary transitions in the mutualism-antagonism continuum

The paper models coevolutionary transitions between mutualism and antagonism, showing ecological changes can trigger bidirectional shifts and identifying a tipping point for mutualism breakdown.

Phase transitions and symmetry breaking of cooperation on lattices

This paper studies cooperation dynamics in a donation game with separated interaction and competition neighborhoods, finding symmetry breaking and phase transitions under different cost-to-benefit ratios.

A complex adaptive systems model of labor reciprocity and normative reasoning in swidden agriculture

The paper develops a complex adaptive systems model of swidden agriculture showing that sustainable high-intensity swidden emerges from balanced labor reciprocity and normative reasoning.

Cheats can boost the success of a cooperative invader

The paper shows that a mix of siderophore-producing and cheating strains of Pseudomonas aeruginosa outperforms pure cooperator or cheater populations in environments where siderophores are beneficial.

Facultative Cheating and Hybrid Vigor Resolves Cooperator-Cheater Conflict in a Yeast Public Goods System.

The paper shows that facultative cheating and hybrid vigor resolve cooperator-cheater conflict in a yeast public goods system by enabling phenotypic flexibility through hybridization.

Positive and negative selective assortment in pairwise interactions

The paper analyzes how selective assortment in partner choice affects evolutionary dynamics and equilibria in populations playing different games.

Fluctuating selection breaks Hamilton's rule for the evolution of altruism

This paper shows that altruism can evolve without assortment mechanisms under fluctuating selection in limited populations, challenging Hamilton's rule.

Power asymmetry destabilizes reciprocal cooperation in social dilemmas

This study shows power asymmetry reduces cooperation in social dilemmas, with different effects in prisoners' dilemma and snowdrift game.

Reconciling ecology and evolutionary game theory or When not to think cooperation

This paper critiques the assumption in evolutionary game theory that all individuals have equal intrinsic growth rates, highlighting its limitations and suggesting a reconciliation with ecology.

A higher-order equivalence of Lotka-Volterra and replicator dynamics reveals tight connections between ecology and evolution

This paper shows that Lotka-Volterra and replicator dynamics are equivalent even with non-linearities, highlighting their connection in ecology and evolution.

Evolution of division of labor on two public goods with continuous investments

This study models division of labor in species producing multiple public goods using adaptive dynamics, showing three potential evolutionary outcomes with varying fitness and payoff variance.

Emergence of cooperation promoted by higher-order strategy updates

This paper investigates higher-order strategy updates in public goods games and finds they enhance cooperation, particularly through group-mutual comparison updates.

Kin-discriminating partner choice promotes the evolution of helping

This study shows that kin discrimination in partner choice increases overall helping behavior compared to indiscriminate helping.

In the face of competition, imperfect knowledge can lead to sustainable exploitation of a shared resource.

The paper shows that imperfect knowledge can lead to sustainable resource exploitation in competitive scenarios without cooperation, resulting in higher long-term yields than omniscient or cooperative strategies.

Time of first contact determines cooperator success in a cross-feeding consortium

The paper shows that the timing of first contact between cooperators determines their success in a microbial cross-feeding consortium.

Strong segregation promotes self-destructive cooperation

The paper shows that self-destructive cooperation can persist under strong segregation by using engineered bacteria and automated experiments.

Evolution of cooperation in multichannel games on multiplex networks

The paper studies cooperation in multichannel games on multiplex networks, finding that network structure and strategy linking enhance cooperation rates when layers are structurally similar and perception errors are low.

Evolution of stable reciprocity through the maintenance of discrimination

The paper challenges a previous study by showing that cooperation through repeated interaction can be stable without between-group competition, by maintaining discrimination through model modifications.

Replicator dynamics generalized for evolutionary matrix games under time constraints

This paper generalizes replicator dynamics for evolutionary matrix games under time constraints, showing that the classical relationship between ESS and stability holds in any dimension with the new dynamics.

The general version of Hamilton's rule

The paper constructs a general version of Hamilton's rule to resolve debates about its generality by showing it can describe various social behaviors and fitness dependencies.

On Long-Term Species Coexistence in Five-Species Evolutionary Spatial Cyclic Games with Ablated and Non-Ablated Dominance Networks

The paper replicates and refutes findings from a previous study on species coexistence in spatial cyclic games, showing that longer simulation runs reveal different asymptotic behaviors and that ablations primarily affect convergence time.

Survival cost sharing among altruistic full siblings in Mendelian population

The paper analyzes the evolutionary stability of altruism in sibling interactions under starvation, showing that Hamilton's rule is sufficient for altruism but not necessary for its stability.

Evolutionary branching in multi-level selection models

This study examines evolutionary dynamics in multi-level selection models, showing that weaker individual-level selection promotes group-level diversification while stronger selection enhances group adaptation.

Spontaneous symmetry breaking of cooperation between species

The paper studies cooperation between species using a spatial prisoners dilemma model, showing four dynamical domains and spontaneous symmetry breaking in cooperation.

Chimerism and altruism

This paper develops a kin-selection model to explore how chimerism affects social behavior and relatedness patterns in structured populations, finding increased altruism and internal conflicts due to somatic and germline chimerism.
