Summary: This study investigates the promotion of cooperation in a population that migrates based on the comparison between local and global environments. The results show that cooperation can be significantly enhanced through the clustering of cooperators and the coalescence of cooperator clusters.

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 studies the formation control of high-order multi-agent systems using aggregative games. The Nash equilibrium of a quadratic aggregative game is found to constitute the desired formation. A distributed algorithm is designed to achieve the desired formation by seeking the Nash equilibrium, with each agent estimating the game aggregate. The convergence of the algorithm is analyzed using Lyapunov stability theory.

Summary: In response to the challenges posed by sudden large-scale migration, a generic framework is proposed for designing agent-based models to simulate conflict instances and the movement of forcibly displaced individuals. Through a concept demonstrator, the framework's utility and feasibility are demonstrated, helping to understand the movement patterns of forcibly displaced people and predict their destinations.

Summary: This article focuses on n-person games in a Euclidean space, where players' locations reflect their affinity. The formation of coalitions can be attributed to close distances between members and the potential benefits gained from alliances. The study determines the likelihood of coalition formation and explores how players' movements within the space can lead to stronger alliances.

Summary: The migration behavior of the population, affected by uncertain and irrational factors, has a significant impact on cooperation evolution in spatial games. Previous studies have considered either random or deterministic migration, but in reality, a mixture of both factors exists. This study examined the effects of a mixture of directional and random migration on cooperation and found that a small proportion of directional migration and lower migration speed promote cooperation. There is an optimal range of directional migration that best promotes the evolution of cooperation.

Summary: This study finds that a trust-driven updating rule based on reputation can significantly promote the level of cooperation. Increasing the heterogeneity parameter helps to enhance cooperation. The correlation between node degree and reputation heterogeneity has an impact on cooperation.

Summary: This study introduces an adaptively adjusted number of interactions based on random neighbors into a spatial prisoner's dilemma game. The results show that adaptively adjusting the number of interactive neighbors can significantly enhance cooperation, and it performs better than traditional deterministic interactions. Cooperation can be promoted by an appropriate interactive neighborhood, which may inspire more research on addressing social dilemmas.

Summary: This study uses an agent-based modeling approach to analyze multidestination travel patterns and spatial spillover effects in visitor flows. The simulation results show varying degrees of spillover effects between destinations for different types of visitors, with a focus on three regions with particularly strong spillover effects: the Bohai Rim region, the Yangtze River Delta region, and the Sichuan and Chongqing region.

Summary: This passage discusses the importance of spatial and kinetic coordination between stem cells and progenitors in maintaining tissue homeostasis in adult tissues. The authors developed a mathematical model to study the rejuvenation of corneal epithelium, exploring the tradeoffs between replicative lifespan, spatial correlation length, and tissue rejuvenation dynamics. The results provide insights into maintaining homeostasis in cellular systems through spatial coordination.

Summary: In this study, a spatial multi-games model under the myopic rule is analyzed, considering population diversity and the limitation of individual information in repeated N-person games. The effects of game intensity parameters, noise parameter, and mixing ratio on the frequency of cooperators are studied using Monte Carlo simulation method. The results show that the noise parameter can promote cooperation under certain conditions, and the impact of the mixing ratio on cooperators is nonmonotonic under myopic mechanism. Additionally, the behavior of cooperators differs between learning update rule and myopic update rule.

Summary: This study explores the effects of investment-allocation scheme on the evolutionary cooperation of spatial public goods game by introducing a parameter alpha. The results demonstrate that moderate investment preferences can promote cooperation for low enhancement levels, while self-interest preferences hinder cooperation for high enhancement levels.

Summary: This mini-review discusses agent-based models as modeling techniques for studying pattern formation of multi-cellular systems in biology. We introduce and compare different agent-based model frameworks with respect to spatial representation, microenvironment, intracellular and extracellular reactions, cellular properties, implementation, and practical use. The guiding criteria for the considered selection of agent-based model frameworks are that they are actively maintained, well documented, and provide a model development workflow.
