Modeling And Study Of Network Rumor Spreading

Regardless of suspiciousness or credulity,we always believe in rumors at a certain moment.Before we notice,rumors will quietly bypass the spiritual defense.Especially in the internet,the authenticity of information is far more difficult to confirm.Moreover,the spreading of rumors through the internet has become stronger than the spread of traditional media,and have greater social impact.Therefore,it is very meaningful to study how to control the spreading of rumors.This paper will model the rumor propagation problem from different angles,combine the different characteristics of specific problems,study the rumor propagation problem through the form of theory and experimental results,and finally give a feasible strategy to control rumor communication.·SIES rumor propagation modelThe rumor ends with the wise,and the most effective way to curb the spreading of rumors is to improve the level of education.However,this method is costly first,and secondly,it cannot be immediately effective.Therefore,it is possible to educate people on the specific rumor so as to improve their knowledge.Based on this direction,this paper proposed a new rumor propagation model.After modeling,we performed a mathematical analysis on the model,quantified the loss caused by rumor propagation and control cost,transformed the original problem into an optimal control problem,and proved that the optimal system has an optimal solution.Then we solved the optimization system and got the optimal control equation.Finally,a series of numerical experiments were carried out to simulate the propagation process of rumors on the model,and the influence of each parameter during the rumor propagation is verified,and finally some feasible strategies for controlling rumors are given.·URTU dual network rumor propagation modelClarifying rumors by releasing the truth is a common way to suppress the spreading of rumors,and the spreading network of rumors and truths tend to be different.Based on this direction,this paper proposed a new rumor propagation model.First of all,we established a reasonable mathematical model for the problem of simultaneous transmission of truth and rumors,and modeled and analyzed it through the knowledge of propagation dynamics,and finally obtained the URTU model at the node level.After modeling,we performed a mathematical analysis of the model,quantified the cost efficiency,and transformed the original problem into an optimization problem with constraints.Then we conducted a series of numerical simulation experiments on the model,which verified that the model has a finite peak.Finally,a series of numerical experiments are used to simulate the propagation process of rumors and truths on the model,verifying the impact of various parameters on the cost efficiency of the model,and finally some strategies that make the cost more efficient are given.
