<h2 id="SYNOPSIS">SYNOPSIS</h2>
<p><code>bbv</code> <var>N</var> <var>m</var> <var>n0</var> <var>w0</var> <var>delta</var></p>
<h2 id="DESCRIPTION">DESCRIPTION</h2>
<p><code>bbv</code> grows an undirected weighted random scale-free graph with <var>N</var>
nodes using the model proposed by Barrat, Barthelemy, and
Vespignani. The initial network is a clique of <var>n0</var> nodes, and each
new node creates <var>m</var> new edges, each with weight <var>w0</var>. The parameter
<var>delta</var> sets the amount of weight to be redistributed in the
neighbourhood of newly-connected nodes.</p>
<h2 id="PARAMETERS">PARAMETERS</h2>
<dl>
<dt class="flush"><var>N</var></dt><dd><p> Number of nodes of the final graph.</p></dd>
<dt class="flush"><var>m</var></dt><dd><p> Number of edges created by each new node.</p></dd>
<dt class="flush"><var>n0</var></dt><dd><p> Number of nodes in the initial (seed) graph.</p></dd>
<dt class="flush"><var>w0</var></dt><dd><p> Weight of each new edge (must be >=0)</p></dd>
<dt class="flush"><var>delta</var></dt><dd><p> The amount of weight to be redistributed among the neighbours of
newly-connected nodes.</p></dd>
</dl>
<h2 id="OUTPUT">OUTPUT</h2>
<p><code>bbv</code> prints on STDOUT the edge list of the final graph, which
consists of three columns:</p>
<pre><code> node1 node2 weight
</code></pre>
<p>where <code>weight</code> is the weight of the corresponding edge. Please note
that each edge is printed only once.</p>
<h2 id="EXAMPLES">EXAMPLES</h2>
<p>The following command:</p>
<pre><code> $ bbv 10000 3 5 1.0 0.5 > bbv_10000_3_5_1.0_0.5.txt
</code></pre>
<p>creates a weighted scale-free graph with <var>N=10000</var> nodes, where each
new node creates <var>m=3</var> new edges and the initial seed network is a
ring of <var>n0=5</var> nodes. Each new edge has an initial weight equal to
<var>w0</var>. The weights of existing edges are rearranged after the addition
of a new edge, by rearranging an amount of weight equal to <var>delta</var>.
The final graph is saved in the file <code>bbv_10000_3_5_1.0_0.5.txt</code>
(notice the STDOUT redirection operator <code>></code>).</p>
