Of particular importance for public health is how to understand strategic vaccination behavior in social networks. Social learning is a central aspect of human behavior, and it thus shapes vaccination individuals’ decision-making. Here, we study two simple models to address the impact of the more rational decision-making of individuals on voluntary vaccination. In the first model, individuals are...
We present a self-learning evolutionary Prisoner's Dilemma game model to study the evolution of cooperation in network-structured populations. During the evolutionary process, each agent updates its current strategy with a probability depending on the difference feedback between its actual score and score aspiration. Each agent's score is a weighed mean of its payoff coming from its neighbors (social...
In this paper, we investigate coevolution of strategy and structure in Prisoner's Dilemma. We concentrate on the noise effect in the topological evolution on cooperation. We assume individuals can either update their strategies by imitating their partners or adjust their social ties. At each time in the strategy evolution, pairwise comparison is employed. While at each time in the topological evolution,...
