Problems solved by technology

However, the research on the spread process of infectious diseases and rumors cannot obtain data through experiments in the population like some other disciplines. Relevant data and materials can only be obtained from existing reports and records, and these data are often not enough. Comprehensive and sufficient, it is difficult to accurately determine certain parameters based on these data for forecasting and control work

Embodiment

[0077] figure 1 It is a flowchart of a limit cycle amplitude control method in a rumor propagation model of the present invention.

[0078] In this example, if figure 1 As shown, a rumor propagation control method in a complex network of the present invention mainly includes the following steps:

[0079] S1. Establish a rumor propagation model

[0080] In real life, the number of users joining the network per unit time is not fixed. Some studies have shown that the growth of the number of users is similar to the population growth in biological populations, which conforms to the logistic growth law. Therefore, the logistic growth law is introduced into the SIR rumor propagation model. Above, build a rumor propagation model:

[0081]

[0082] Among them, S represents a healthy node, I represents a propagation node, R represents an immune node, α represents that when a rumor propagation node contacts a healthy node, a healthy node becomes a propagation node I with a probabi...

Abstract

The invention discloses a limit cycle amplitude control method in a rumor propagation model. A new rumor propagation model is established on the basis of the SIR model. Considering that the infection rate decreases as the number of nodes spreading rumors increases, a piecewise function is introduced. To describe the infection rate, this can more accurately describe the rumor spreading behavior in complex networks. Secondly, on the basis of the new model, a control function is introduced, and the control function is added to the model to control the amplitude of the limit cycle in the rumor propagation model, thereby controlling the fluctuation range of the number of people spreading rumors.

Description

technical field [0001] The invention belongs to the field of complex network propagation dynamics, and more specifically relates to a limit cycle amplitude control method in a rumor propagation model. Background technique [0002] The basic research object of propagation dynamics is the relationship between the properties of dynamic models on different networks and the static statistical properties of the corresponding networks, including known and unknown static geometric quantities. However, the research on the spread process of infectious diseases and rumors cannot obtain data through experiments in the population like some other disciplines. Relevant data and materials can only be obtained from existing reports and records, and these data are often not enough. Comprehensive and sufficient, it is difficult to accurately determine certain parameters based on these data for forecasting and control work. Therefore, it is an important research method of current communication...
