We propose and investigate a unifying class of sparse random graph models, based on a hidden coloring of edge-vertex incidences, extending an existing approach, random graphs with a given degree distribution, in a way that admits a nontrivial correlation structure in the resulting graphs. The approach unifies a number of existing random graph ensembles within a common general formalism, and allows for the analytic calculation of observable graph characteristics. In particular, generating function techniques are used to derive the size distribution of connected components (clusters) as well as the location of the percolation threshold where a giant component appears.
我们提出并研究了一类统一的稀疏随机图模型,该模型基于边 - 顶点关联的隐藏着色,以一种在所得图中允许非平凡相关结构的方式扩展了现有的具有给定度分布的随机图方法。这种方法在一个通用的形式体系内统一了许多现有的随机图系综,并允许对可观测的图特征进行解析计算。特别地,生成函数技术被用于推导连通分量(簇)的大小分布以及出现巨分量的渗流阈值的位置。
