<h2 id="DESCRIPTION">DESCRIPTION</h2>
<p><code>hv_net</code> samples a random graph whose joint degree distribution is
equal to that of another graph provided as input, using the
hidden-variable model proposed by Boguna ans Pastor-Satorras.</p>
<h2 id="PARAMETERS">PARAMETERS</h2>

'-' (dash), read the edge list from STDIN.</p></dd>
<dt class="flush">SHOW</dt><dd><p> If the second parameter is equal to <code>SHOW</code>, the program prints on
STDERR the hidden variable and actual degree of each node.</p></dd>
</dl>
<h2 id="EXAMPLES">EXAMPLES</h2>
<p>Let us assume that we want to create a graph whose joint degree
distribution is equal to that of the graph contained in
<code>AS-20010316.net</code> (i.e., the graph of the Internet at the AS level in
March 2001). We can use the command:</p>
<pre><code> $ hv_net AS-20010316.net > AS-20010316.net_rand
</code></pre>
<p>which will sample a random graph with the same joint-degree
distribution and will save its edge list in the file
<code>AS-20010316.net_rand</code> (notice the STDOUT redirection operator
<code>></code>). Additionally, we can also save the values of the hidden
variables and actual degrees of the nodes by specifying <code>SHOW</code> as a
second parameter:</p>
<pre><code> $ hv_net AS-20010316.net SHOW > AS-20010316.net_rand 2>AS-20010316.net_rand_hv
</code></pre>
<p>In this case, the file <code>AS-20010316.net_rand_hv</code> will contain the
values of the hidden variable of each node and of the actual degree of
the node in the sampled graph, in the format:</p>
<pre><code> h1 k1
h2 k2
....
</code></pre>
