有序递增k树:偏好连接网络模型的介绍和分析

Ordered increasing k-trees: Introduction and analysis of a preferential attachment network model

Alois Panholzer, Georg Seitz

摘要:

我们介绍了一个随机图模型的基础上k-树,它可以通过应用概率优先连接规则,但也有一个简单的组合描述。我们对网络模型的重要参数进行了精确的分布分析,如度,局部聚类系数和节点的后代数量以及根到节点的距离。我们不仅得到随机节点的结果,而且特别地,我们还得到了大小为n的随机k树中第j个插入节点的参数行为的精确描述,其中j = j(n)可能随n增长。所提出的方法并不局限于这个特定的k树模型,但也可以应用到其他不断发展的k树模型。

英文摘要:

We introduce a random graph model based on k-trees, which can be generated by applying a probabilistic preferential attachment rule, but which also has a simple combinatorial description. We carry out a precise distributional analysis of important parameters for the network model such as the degree, the local clustering coefficient and the number of descendants of the nodes and root-to-node distances. We do not only obtain results for random nodes, but in particular we also get a precise description of the behaviour of parameters for the j-th inserted node in a random k-tree of size n, where j = j(n) might grow with n. The approach presented is not restricted to this specific k-tree model, but can also be applied to other evolving k-tree models.
