Embodiment
[0037] Such as figure 1 As shown, an embodiment of the present invention is based on a multi-agent simulation method for information dissemination and public opinion evolution, and simulates information dissemination and public opinion evolution.
[0038] 1) The construction process of BA scale-free network is as follows:
[0039] A) initial generation m 0 random network of nodes.
[0040] B) Add a node every time, and connect with known m nodes, m0 , the probability of connection is proportional to the degree of the node.
[0041] C) Repeat the above steps until the stop condition is met.
[0042] A network of 200 nodes built according to this method is as follows figure 2 shown.
[0043] 2) Construction of information dissemination model
[0044] In the process of information dissemination, we use informed to indicate whether each node in the network is informed, and spread to indicate the node's propagation status. At the initial moment when the message enters the n...
