Type of network | Network description |
---|---|
Erdős-Renyà (ER)[37] | The oldest class of random networks. To construct a graph instance, links are added between each pair of nodes with probability p (a parameter). |
Watts-Strogatz (WS)[36] | A kind of generalization of ER networks in which links of a regular lattice are rewired. Characterized by high clustering coefficients and short average path lengths. |
Barabási-Albert (BA)[19] | A class of random networks constructed one node at a time, with new nodes preferentially attaching to existing high-degree nodes. These networks are scale-free (i.e. hub-like) and more closely resemble molecular interaction network networks than ER or WS networks. |
Duplication-divergence | These networks, inspired by gene duplication and subsequent divergence (in sequence, interaction and function) [38] are generated by duplicating nodes and randomly removing/adding links. Architecturally, duplication-divergence networks are similar to Barabási-Albert networks [39, 40] |
Fixed node degrees | Random networks characterized by their specific node degree sequences that are generated either by randomly rewiring the links of an existing network [41] or through the configuration model [42, 43]. |
