Embodiment

[0039] figure 1 It is a flow chart of a rumor propagation control method in a complex network of the present invention.

[0040] 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:

[0041] S1. Establish a rumor propagation model;

[0042] S2. Obtain the optimal control variable;

[0043] S3. Suppress the spread of rumors.

[0044] The present invention is specifically set forth below for above-mentioned three steps, as follows:

[0045] S1. Establish a rumor propagation model.

[0046] 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:

Abstract

The invention discloses a method for controlling rumor propagation in a complicated network. A new rumor propagation model is established on the basis of an SIR (susceptible, infected and removed) model, a fact that the infection rate is reduced along with the increase of nodes for rumor propagation is considered, and the infection rate is described by introducing a piecewise function, so that rumor propagation behaviors in the complicated network can be more accurately described; an optimum control variable is introduced on the basis of the new model, the optimum control variable can be calculated by a mathematical method and is added into the model, so healthy nodes can be converted into immune nodes as many as possible, and the nodes for rumor propagation in the network are minimal, and the aim of controlling the rumor propagation is fulfilled.

Description

technical field [0001] The invention belongs to the field of complex network propagation dynamics, and more specifically relates to a rumor propagation control method in a complex network. Background technique [0002] A complex network refers to a large-scale network with complex topology and dynamic behavior, which is a graph composed of a large number of nodes connected to each other through edges. E.g, [0003] The Internet, biological network, wireless communication network, highway network, power network, epidemic and rumor spreading network are all complex networks. [0004] 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...
