Erdős–Rényi model - Wikipedia
WEBNetwork science. In the mathematical field of graph theory, the Erdős–Rényi model refers to one of two closely related models for generating random graphs or the evolution of a random network.

The Erdős–Rényi models (Chapter 2) - Complex Networks
WEBAug 5, 2013 · Summary. Before 1960, graph theory mainly dealt with the properties of specific individual graphs. In the 1960s, Paul Erdős and Alfred Rényi initiated a systematic study of random graphs [ER59, ER60, ER61]. Some results regarding random graphs were reported even earlier by Rapoport [Rap57].
Erdös-Rényi (ER) Random Networks - NeuroData
WEBThis simple random network model is called the Erdös Rényi (ER) model, which was first described by [1] and [2]. The way you can think of an ER random network is that the edges depend only on a probability, p, and each edge is totally independent of all other edges.
