Summary: The study suggests that dynamically evolving interaction networks provide a novel explanation for the evolution of spiteful behaviors. In dynamic networks, spiteful behaviors can emerge even when other behaviors are positively correlated and the average degree of correlated interaction in the population is low, due to transient and partial anti-correlated interactions. The findings show that feedbacks with network structure can favor the evolution of spite by creating correlated and anti-correlated behavioral interactions simultaneously.

Summary: Unlike traditional time series, human decision-making involves various cognitive processes, such as beliefs, desires, intentions, and theory of mind. This study proposes the use of LSTM-based recurrent neural network architecture to predict the time series of human actions in gaming activities, showing superior performance compared to state-of-the-art methods in both single-agent and multi-agent scenarios.

Summary: This study introduces a coevolutionary model based on the weak prisoner's dilemma and explores the evolutionary dynamics of cooperation under different levels of social interaction sensitivity and temptation to defect. The simulation demonstrates that sparse cooperator clusters can expand greatly when social interaction sensitivity and temptation to defect are low. On the other hand, dense cooperator clusters form rapidly in a high social interaction sensitivity, providing protection against high temptation.

Summary: This study proposes a coevolutionary model in the prisoner's dilemma game, where the community environment determines the anti-social revenue structure. It is found that individuals' perception of the external environment can trigger antisocial behavior by influencing their perception of antisocial revenue. Additionally, their past strategic information also plays a similar role. Simulation results show that this mechanism significantly improves cooperation, especially when sensitivity to the environment is taken into account. Analysis also reveals that different optimal cooperative levels can result from a lack of experience and insufficient environmental information.

Summary: This paper investigates the existence of cooperative strategies in diverse networked populations, which may result in a lower payoff for the focal player but also lead to an even lower payoff for their partner, thus reducing the overall benefits of the populations; these strategies are capable of winning with a high probability against opponents with an unknown strategy, and they exhibit survival advantage and robust fitness in evolutionary processes.

Summary: In this study, the frequency-dependent interactions between a gefitinib-resistant non-small cell lung cancer population and its sensitive ancestor were measured experimentally. The cost of resistance was found to be insufficient in predicting competitive exclusion, and frequency-dependent growth rate measurements were necessary. Simulations showed that ecological growth effects can influence the predicted extinction time.

Summary: Prosociality and cooperation are fundamental human traits but cultural norms can influence social relations. The study finds that cultural variation in resource sharing is limited, indicating a common foundation for everyday cooperation worldwide. Requests for immediate assistance are frequent and often successful, with individuals giving reasons when they decline to help. This research highlights the significance of cross-cultural understanding in promoting prosocial behavior.

Summary: This paper investigates stochastic two-strategy evolutionary games with multiplicative noise interference and studies their stability, especially focusing on the impact of multiplicative noise on cooperation behavior in large well-mixed populations. The study establishes sufficient conditions on stochastic noise for stable equilibrium points of general two-strategy games to be almost sure exponentially stable (ASES). The stochastic Lyapunov framework is utilized to prove stochastic stability, with the key challenge lying in finding suitable Lyapunov functions.

Summary: This paper investigates the impact of different heterogeneous distributions on the evolution of cooperation on a 2D square lattice, revealing the varying effects of heterogeneous stochastic interactions on different types of social dilemmas. Specifically, cooperation evolution is significantly facilitated in the prisoner's dilemma game and snowdrift game, while it may be impeded by heterogeneously stochastic interactions in the stag hunt game.

Summary: This paper investigates the impact of resource interaction between interdependent networks on public cooperation. The redistribution mechanism of payoffs between the upper and bottom networks based on the gap of payoffs leads to a non-monotonic influence on the cooperation level of the upper network, while network reciprocity fails on the bottom network. The behavior of sponsors and recipients within cooperators and defectors contributes to the equilibrium state, which is attributed to the evolution of correlated cooperator pairs between interdependent networks. Our results provide a theoretical analysis of group cooperation induced by resource interaction factors.

Summary: Researchers in this study analyzed the strategies in alternating games through mathematical characterization and evolutionary simulations, finding that mutual cooperation still evolves under various model extensions and parameter values. However, in noisy environments, alternating games require different strategies to maintain cooperation, and none of the strategies are evolutionarily stable.

Summary: Indirect reciprocity investigates how social norms promote cooperation by continuously monitoring and assessing social interactions. This study shows that nuanced assessments of observations can mitigate disagreements and errors in situations where information is private and unreliable. Such quantitative assessments are error-correcting and may help sustain cooperation in natural populations.

Summary: In this study, we investigate the impact of the environment on evolutionary competition in a growing habitat with vacancies using evolutionary game dynamics. We find that as the environment becomes harsh, a transition from growing populations to extinction occurs. The occurrence of this transition point depends on the strategies present in the population. Interestingly, we observe a 'cooperative window' where only cooperators can survive. Furthermore, vacancies provide spatial selection and enhance cooperation.

Summary: In stochastic games, the feedback loop between social behaviors and the environment plays a crucial role. Precise knowledge of the environment often leads to more cooperation, but there are cases where ignorance can also be beneficial. This study examines the impact of information availability on the evolution of cooperation in stochastic games.

Summary: Human interactions can lead to social dilemmas, where individuals are tempted to free ride despite the collective benefit of cooperation. Repetition of interactions allows for the adoption of reciprocal strategies, incentivizing cooperation. The repeated donation game is a basic model for direct reciprocity, where strategies depend on the previous rounds. Analyzing the adaptive dynamics of these strategies has been challenging, but this study derived and analyzed their dynamics, characterizing the space of memory-one strategies.

Summary: Individuals use past experience to shape future behaviors, and the learning outcome depends on the objective of maximizing. Interactions between selfish learners can be harmful to both, but evolutionary pressure favors learning rules with social preferences. Experimental data shows that selfish learning fails to explain human behavior when there is a trade-off between payoff maximization and fairness.
