摘要
We introduce a 網絡 growth model based on complete redirection: a new node randomly selects an existing target node, but attaches to a random neighbor of this target. For undirected 網絡s, this simple growth rule generates unusual, highly modular 網絡s. Individual 網絡 realizations typically contain multiple macrohubs-nodes whose degree scales linearly with the number of nodes N. The size of the 網絡 'nucleus'-the set of nodes of degree greater than one-grows sublinearly with N and thus constitutes a vanishingly small fraction of the 網絡. The 網絡 therefore consists almost entirely of leaves (nodes of degree one) as N -> infinity
