## This is the vertical participation model. For each node i, we use
|
|
## exactly the same value of B_i as in the original network, but we
|
|
## choose at random the layers in which node i will be active. This
|
|
## breaks down intra-layer correlations.
|
|
##
|
|
## We get as input a file which reports, for each value of B_i, the
|
|
## number of nodes in the original network which have that value, i the format:
|
|
##
|
|
## B_i N(B_i)
|
|
##
|
|
##
|
|

|
|
## The output is the obtained distribution of bit-strings.
