generate_edges bug

[karandeep-johar]

If i understand your program correctly you are first electing the first vertex of the edge and then selecting the second vertex of the edge. Say we have a 2x2 matrix with RMAT parameters as a,b,c,d. where a+b+c+d=1. Then probability of edge (1,1) occurring should be a according to the definition of RMAT graphs. But in your program it would be (a+b)(a+c) which is not the same as a. Have I misunderstood something?
I think you can't break down the probability of an event occurring into two independent events like this.
