Procedure MakeRelations

	Input: bivariate attribute distributions {βi,j}i=1..m;j=1..l, bivariate degree distributions ${\left\{\stackrel{=}{{\chi }_j}\right\}}_{j=1,,l}$, individual attributes {xi}i=1..m and ideal degrees {dj}j=1..l, the population V
	Output: E
1	$E=\varnothing$
2	foreach i in 1... |V| do
3	foreach j =1...l do
4	$N_j\left(v_i\right)≔\varnothing$.
5	foreach e = 1...dj(v) do
6	Schedule AddEdge(vi, j) to take place at time $\frac{1}{ei+1}$.
7	Wait until time 1.
8	$E≔{\bigcup }_{i=1}^{\mid V\mid }{\bigcup }_{w\in N\left(v_i\right)}\left\{(v,w)\right\}$
9	return E
