In Nature and human society, cooperative behavior, such as the Lions in the African Grassland cooperative predation, human society's production and management cooperation, as well as the global greenhouse gas carbon emissions management, and so on, need to be coordinated between groups to achieve. But in a group, not all individuals are willing to act cooperatively, because the individual has a certain self-interest mentality, some people will take the act of non-cooperation (that is, betrayal). In this context, how the cooperative behavior is generated and maintained among the selfish individual, has been widely concerned by experts and scholars in the fields of economy, politics, society, psychology, biology, computer and so on, becoming a research hotspot. Evolutionary game theory is regarded as one of the most powerful tools to study cooperative behavior. According to the data of China Statistical Yearbook 2012, at the end of 2012, the number of college students in the country was 25,365,647. College students are the middle power of the future society, and also an important part of maintaining social stability. At present, in addition to the professional learning-oriented composition of class, professional, college and other levels of relationship, there are many forms of group existence, such as student associations, public welfare activities, loose interest groups, scientific research teams and other forms, the relationship between these students of the reasonable description and characterization, And the emergence of cooperative behavior in groups and the emergence of the conditions are worth analysis and research. In addition, from the school level to understand, at present, all kinds of new student group organization structure form is also emerging, such as school District system, college system, the organization and management mechanism between student groups, the interaction mechanism between individual students is also a very worthy of exploration of the problem. This project takes the university student Community Relation network as the research object, uses the complex network model to depict the interpersonal relationship of the students to carry on the research of the evolutionary game cooperation behavior, analyzes the change rule of the social cooperation behavior of the university students in the relationship network depicted by different network structure, Comparing what kind of complex network model is more advantageous to the generation of cooperative behavior in game model. At the same time, taking into account the inherent tendency of students, immediate discount preferences, direct reciprocity, indirect reciprocity and other factors to the community's overall cooperative tendencies, and find out what mechanism and what conditions can promote the emergence of cooperative behavior in college students community. Through the study of dynamic network structure to reflect the interpersonal relationship in real life, and through the study of college students Cooperative Behavior to guide the construction of a more conducive to the emergence of cooperative behavior of the new college students community, improve the student community learning enthusiasm and cooperation enthusiasm, the formation of a benign interaction of the cooperative groups. |
