What is the runtime of the algorithm? Correct, as there are n * n possible edges, the runtime is O(n^2). Include edge e with (independent) probability p into the graph.Here’s how the basic Erdős–Rényi graph generator works: So there is no bias towards a specific type of graph. An important property of random graphs generated under this model is that, given a set of vertices and a number of edges, all possible graphs are generated with the same probability. In most cases, when referring to “random graphs”, people assume the underlying “Erdős–Rényi model” as a graph generator (it’s named after the mathematicians Paul Erdős and Alfréd Rényi). What’s the Erdős–Rényi Random Graph Generation Model? More precisely, there’s a probability distribution over all possible graphs that describes how likely each graph is selected by the random process. Now, given that you have a finite number of vertices n, there is also a finite number of graphs that can be generated from those vertices (although the number of graphs with n vertices grows exponentially).Ī random graph is just one of those graphs-which is generated by a random process. The NumPy Alternative to Generate a Random GraphĪccording to Merriam-Webster, a graph is “a collection of vertices and edges that join pairs of vertices According to Merriam-Webster, a graph”.Įvery edge connects exactly two vertices.What’s the Erdős–Rényi Random Graph Generation Model?.
