Evolution Of Opinion Dynamics In Complex Networks

In the real world,people have different opinions on the same issue or event,that is,they hold different opinions.Individuals' opinions are influenced by neighboring neighbors.Because individuals have differences,different individuals are affected in different way by neighbors' opinions.In this paper,the influence of the number of different opinions in the neighbor on the evolution of the system is studied on the one-dimensional and two-dimensional rugular networks.It is found that different network structures and different numbers of neighbor opinions will influence the opinion dynamics of the system.Various network basic models and the research methods is introduced in the preface,including two examples of directed networks and community networks.Opinion model and opinion dynamics review on the complex network was introduced in the second chapter,meanwhile,complex system opinion is researched in different updates dynamics on the complex networks.we make a simple conclusion by calculation subsequent in opinion dynamics,which imply opinion spreading slowly on the network with lower agglomerating coefficient in the special update rule,but eventually it can reach an overall equlibrium.Opinion in dynamics are greatly affected by the network.It can be known that the equilibrium time is related to the effective size of the system by analyzing the sequent of opinion dynamics.The network structure can affect the effective size of the system,which can make the system reach equlibium that is differrent.If we can know the impact of network structure on opinion dynamics and game dynamics precisely,we can remove or add a key node in the network so that the system can reach the steady state as soon as possible.Monte Carlo simulation was used in the opinion dynamics.The prospect was great,We summarized our previous paper and discussed prospective in the third chapter: Firstly,the interaction patterns between individuals(network structures)and individual opinion(strategy)update rules significantly affect the evolution of system opinion(strategy).Therefore,different network structures,especially dynamic networks and individual opinion(strategy)updating rules is still the focus of the future,which impact system evolution dynamics.Secondly,the evolution of network dynamics is based on the statistical laws of the system,which cannot prevent fluctuation appearance in the system.The influence of system fluctuations oftens occur no regular in the system,which make the scientist fail to predict fluctuations precisely.The fluctuation analysis only can be used to explain the unusual phenomenon.In the future,Precision of the science will be developed and become more important.
