Relationships between people in real life are dynamically changed with the interaction process, and due to the heterogeneous preferences, this change is different from person to person. Based on this observation, we propose a new spatial and weighted prisoner's dilemma game model with heterogeneous individuals. Two types of tags, namely, tag-F (concerned about social fairness) and tag-W (concerned about personal well-being), are introduced to describe individuals' different preferences. The link weights indicating the interaction strength between individuals are updated based on different rules that depend on their tags. Through simulations, we verify that a large link weight control factor and a high proportion of tag-F individuals favor the emergence and persistence of cooperation. In addition, an increase in the link weight sensitivity factor favors the evolution of cooperation when the link weight control factor is small. Moreover, while the level of cooperation increases with the proportion of tag-F type in the population, contrary to our intuition, when the population consists entirely of tag-F individuals, in some cases, cooperation cannot reach a higher level compared with the situation when they are mixed with tag-W type. However, at high dilemma intensities, cooperators emerge only when the entire population consists of tag-F type. These results may provide some new insights into the impact of the evolutionary weighted network with heterogeneous preferences on collective cooperative behavior.
现实生活中人与人之间的关系是随着互动过程动态变化的，由于个体的异质性偏好，这种变化因人而异。基于这一观察，我们提出了一种新的具有异质个体的空间加权囚徒困境博弈模型。引入了两种类型的标签，即标签-F（关注社会公平）和标签-W（关注个人福祉），以描述个体的不同偏好。个体之间的链接权重表示相互作用强度，根据依赖于其标签的不同规则进行更新。通过模拟，我们验证了较大的链接权重控制因子和较高比例的标签-F 个体有利于合作的出现和持续。此外，当链接权重控制因子较小时，链接权重灵敏度因子的增加有利于合作的进化。此外，虽然合作水平随着群体中标签-F 类型的比例增加而增加，但与我们的直觉相反，当群体完全由标签-F 个体组成时，在某些情况下，合作水平无法达到与混合标签-W 类型时相比更高的水平。然而，在高困境强度下，只有当整个群体都是标签-F 类型时，合作者才会出现。这些结果可能为具有异质偏好的进化加权网络对集体合作行为的影响提供一些新的见解。
