Re: [igraph] exponential graph

[Amit Kumar]

Hello Gabor,
Sorry my fault. I will try to be more precise this time.
I need to generate random graph having exponential degree distribution. Where no of nodes in the graph is 100 and probablity that an edge between two randomly picked vertices exists is 0.15.

Amit, I'm sorry, but you have to be a bit more precise.

What is an exponential graph? A graph with exponential degree distribution?

The of probability of what exactly is 0.15? That an edge between two
randomly picked vertices exists?
