The Study Of Several Issues Of Complex Networks

With the development of Internet and Society,the space for information dissemination has broken through the limitations of physical space,and the links between people have become closer.Meanwhile,human society has been inseparable from software systems,and various complex network systems are full of our life.At present,complex network theory has achieved good results in network control,network evolution,network information mining,network defect mining,network prediction and network dynamics.In the paper,the complex network theory is used to study the process of knowledge dissemination in social networks.Simultaneously,it proposes a cooperative learning model based on interactive network to enhance the effect of offline learning.In addition,in software engineering,the complex network is used to study the evolution of software networks.In order to propose new research methods for the more complex and large-scale software internal structure research,the details are as follows:1.Based on the theory of complex networks,in the paper,the process of knowledge diffusion is studied: based on the social phenomenon that people like to spread knowledge to acquaintances,a friendship-based altruistic knowledge diffusion model(SIH model)is proposed.Through the second-order guidance of the mean field equation,the influencing factors of the change of susceptible individuals and infected individuals are analyzed,which affects the influence of knowledge dissemination and knowledge receivers on knowledge dissemination.Through simulation experiments,the influence of different topological structures on knowledge diffusion process are analyzed in the model.2.Based on the research of friendship-based altruism motivation knowledge propagation model,a collaborative learning model based on interactive network is proposed.Firstly,a mobile application based on WIFI hotspot is developed to collect the interaction time between individuals.Thereby constructing an interactive network;and using the interaction behavior between individual students in collaborative learning,constructing a collaborative learning model based on interactive network;in the two-year teaching experiment,by calculating the performance of 12 different classes and different stages It is verified that the learning mode can play a certain role in addition to classroom learning.3.Using complex network theory,we can study the structural characteristics and evolution characteristics of software networks in software engineering: aiming at the current modular software development model,exploring the evolution of software architecture by using the dependencies between object classes to build a software network;The network-centric box counting method calculates the fractal dimension of different modules in different software networks and analyzes the coverage of software network module functions.In addition,the relationship between multi-fractal features of different software networks and different versions of software networks and software module differences is analyzed for the functional differences between software modules.
