NAME

er_A - Sample a random graph from the Erdos-Renyi model A

SYNOPSIS

er_A N K [fileout]

DESCRIPTION

er_A samples a random graph with N nodes and K edges from the Erdos-Renyi model A, i.e. the ensemble of random graphs where K links are placed uniformly at random among N nodes. The program dumps the edge list of the resulting graph on output. If the optional fileout is provided, the output is written on a file with that name.

PARAMETERS

N

Number of nodes in the final graph.

K

Number of edges in the final graph.

fileout

The (optional) name of the filename where the edge list of the graph will be saved.

EXAMPLES

The following command:

     $ er_A 1000 3000

samples an undirected random network with N=1000 nodes and K=3000 edges using the Erdos-Renyi model A. The output of the command er_A will be the edge-list of the resulting graph, where each (undirected) edge is reported only once. In order to be useful, such edge-list should be saved into a file. The following command:

      $ er_A 1000 3000 > er_A_1000_3000.net

will save the resulting graph in the file er_A_1000_3000.net. Notice the usage of the symbol ">" to redirect the output of the program to a file.
