Summary: There are concerns about reinforcement algorithms learning tacit collusion in oligopolistic pricing and their difficulty in regulation. This study shows the connection between evolutionary game theory and reinforcement learning, demonstrating when the latter's rest points are Bayes-Nash equilibria and deriving a Pigouvian tax system for implementing an unknown socially optimal outcome. Simulation results illustrate the collusion capacity of reinforcement algorithms in a simple setting, but the introduction of optimal taxes leads to a competitive outcome.

Summary: With the development of autonomous and intelligent techniques, vehicles are equipped with computation and communication modules to handle on-vehicle computing requests. However, due to limited computation capacities, these requests are offloaded to special devices like roadside units or intelligent vehicles. Two challenges arise in vehicular edge computing networks: accurately determining peak or low hours and effectively offloading requests. This paper investigates computational requests offloading in different vehicular networking scenarios and proposes algorithms based on fuzzy inference and reinforcement learning to address these challenges. Experimental results show significant improvement in resource utilization compared to the benchmark.

Summary: This paper proposes a computation offloading and task scheduling scheme based on pointer network, which can maximize the number of offloading executions of computation tasks and satisfy the priority of computation offloading. The tasks are divided into two types based on whether they can be executed on the vehicle's device, and a two-stage offloading policy is provided. Then, a task offloading decision and scheduling scheme based on pointer network is proposed. Finally, a deep reinforcement learning algorithm is used to train the pointer network for task offloading decision-making and scheduling. The experimental results demonstrate the effectiveness of the proposed scheme.

Summary: Federated learning is a widely researched area due to its ability to break data islands. It brings positive impacts on privacy protection and data cooperation by not uploading client data to a central server. However, some clients are unwilling to participate in federated learning due to resource limitations or potential economic risks. To encourage participation, DFHelper provides collaborative computing services for powerless clients and an incentive mechanism for all roles involved, relieving computing pressure and providing reasonable rewards.

Summary: This article proposes the concept of coded edge federation (CEF) to address the limited computational resources faced by edge infrastructure providers (EIPs) in supporting CDC tasks in edge networks. The CEF is modeled using evolutionary game theory, and fractional replicator dynamics with power-law fading memory is introduced to support EIPs that are economically aware. Theoretical analysis and numerical experiments confirm the existence and stability of equilibrium in the fractional evolutionary game.

Summary: This paper discusses resource allocation problems in human relationship patterns using a new formalism that allows for continuous values of resource costs. The study shows that there is a characteristic parameter eta, analogous to the ratio of relationships between adjacent circles in the discrete case, which has a value similar to 6. The findings suggest the existence of a universal feature in how humans manage relationships, and that online personal networks mirror offline relationship structures.

Summary: This study examines policies aimed at reducing negative externalities and explores their differential impact on genders. Through a driving experiment, it is found that slower driving speeds are the safest option, while faster speeds have higher potential payoffs but also higher accident probabilities. The study further reveals that policies utilizing different framing and endogenously determined punishment mechanisms are only effective for female drivers.

Summary: In this work, the authors assess the role of the adaptation of the interaction network among agents in reaching global coordination and equilibrium selection. They find that the system exhibits fragmentation before reaching full coordination, but coevolution enhances the selection of payoff-dominant equilibrium in a coordination game with risk. Moreover, there is an intermediate range of plasticity values where the system fully coordinates on a single component network.

Summary: This article introduces the definitions and properties of the fast massive unsupervised outlier detection (FastMUOD) indices in functional data. FastMUOD detects outliers by calculating amplitude, magnitude, and shape indices for each curve to target the corresponding types of outliers. Several methods adapting FastMUOD to outlier detection in multivariate functional data are proposed, including applying FastMUOD on the components of the multivariate data and using random projections. Furthermore, these techniques are tested on various simulated and real multivariate functional datasets. Compared with the state of the art in multivariate functional OD, the use of random projections showed the most effective results with similar, and in some cases improved, OD performance. Based on the proportion of random projections that flag each multivariate function as an outlier, a new graphical tool called the magnitude-shape-amplitude (MSA) plot is proposed for visualizing the magnitude, shape, and amplitude outlyingness of multivariate functional data.

Summary: In social interactions, human decision-making, attitudes, and beliefs about others are influenced by factors such as cognitive processes, social influences, and cost-benefit considerations. This study aims to understand these dynamics by using mathematical modeling and an online behavioral experiment. The results show that personal norms and conformity with peers have the largest impact on decision-making, while material benefits and normative expectations have smaller effects. Messaging can change these dynamics by decreasing personal norms and increasing conformity. The study highlights the importance of understanding the dynamics of personal beliefs and beliefs about others in social behavior.

Summary: This study uses online human experiments to investigate the effects of hierarchical structures on cooperation and conflict within groups. The results show that cooperation can be maintained through dyadic conflicts that punish noncooperators, leading to stable hierarchical groups with high levels of cooperation. These findings align with earlier theoretical models and provide insights into the relationship between hierarchy, cooperation, and conflict.

Summary: Culture and social structure are intertwined phenomena observable in personal networks, and can be predicted by specific combinations of personal network structural measures such as closeness, clustering, betweenness, and average degree. The findings support the theory of Grid/Group that emphasizes the interdependence of social structural and cultural features.
