谣言在一个小世界空间网络中慢慢传播

Rumours spread slowly in a small world spatial network

Jeannette Janssen, Abbas Mehrabian

摘要:

谣言传播是一种协议,用于通过用户对用户的交互对网络中的信息传播进行建模。空间偏好连接(SPA)模型是一种用于复杂网络的随机图模型:顶点被放置在度量空间中,并且链接概率取决于顶点之间的度量距离和它们的度。我们发现,SPA模型通常产生的图形,具有小的有效直径,即$O(\log^2 n)$,而谣言传播相对缓慢,即多项式在$n$。

英文摘要:

Rumour spreading is a protocol for modelling the spread of information through a network via user-to-user interaction. The Spatial Preferred Attachment (SPA) model is a random graph model for complex networks: vertices are placed in a metric space, and the link probability depends on the metric distance between vertices, and on their degree. We show that the SPA model typically produces graphs that have small effective diameter, i.e. $O(\log^2 n)$, while rumour spreading is relatively slow, namely polynomial in $n$.
