Problems solved by technology

However, most of the existing optimization methods for virus transmission control use disconnection and reconnection to control, but the cost of disconnection and reconnection is higher than that of simply deleting borders, and it is more complicated to implement, and it does not take into account limited resource constraints

Abstract

The present invention provides a viral transmission control method based on limited temporary frame erasure. The method comprises the steps of: constructing a viral transmission model, and establishing a susceptible-chromophilous-susceptible viral transmission model based on cellular automaton; giving a network graph G(N, E), initializing an adjacent matrix A(t) of the network at a t moment, and selecting m% nodes as primary infection sources; employing a community structure discovery algorithm to obtain a frame erasure sequence based on a whole network frame betweenness; employing the breadthfirst search algorithm to determine that the number of the frame erasure is k%, wherein k is a finite positive integer; according to the frame betweenness frame erasure sequence, temporarily erasinga frame meeting conditions; and repeating the previous step until the proportion of the temporary frame erasure reaches k%. The viral transmission control method is simple and efficient, and can obviously reduce the viral transmission speed and the infection scale.

Description

technical field [0001] The invention belongs to the technical field of computers, and in particular relates to a virus propagation control method based on limited temporary border deletion. Background technique [0002] With the continuous deepening and development of theoretical research on complex networks, more and more researchers are concerned about the dynamics of virus transmission on complex networks, such as the spread of viruses on computer networks, rumors on social networks, the spread of public opinion, and diseases in biological networks. dissemination, etc. [0003] In real life, each individual has the behavior of seeking advantages and avoiding disadvantages. Similarly, for nodes in the network, they will also avoid contact with infected nodes by changing their network structure. Therefore, the topology of the network is no longer static. [0004] In the research of Ji Peng et al., according to the relationship between edges and important nodes, the edges ...
