<code>dijkstra</code> - <span class="man-whatis">Compute the distance between one node and all the other nodes of a weighted graph</span>
</p>
<h2 id="SYNOPSIS">SYNOPSIS</h2>
<p><code>dijkstra</code> <var>graph_in</var> <var>node</var></p>
<h2 id="DESCRIPTION">DESCRIPTION</h2>
<p><code>dijkstra</code> computes the distance (and the shortest paths) between a
given node and all the other nodes of an undirected weighted graph
provided as input. The program implements the Dijkstra's algorithm.</p>
<h2 id="PARAMETERS">PARAMETERS</h2>
<dl>
<dt><var>graph_in</var></dt><dd><p> input graph (edge list) if equal to <code>-</code> (dash), read the edge list
from STDIN.</p></dd>
<dt class="flush"><var>node</var></dt><dd><p> The label of the node from which distances are to be computed</p></dd>
</dl>
<h2 id="OUTPUT">OUTPUT</h2>
<p><code>dijkstra</code> prints on the standard output the distances betwen <var>node</var>
and all the other nodes of the graph, in the format:</p>
<pre><code>d0 d1 d2 d3.....
</code></pre>
<p>where <code>d0</code> is the distance to node <code>0</code>, <code>d1</code> is the distance to node
<code>1</code>, and so forth.</p>
<h2 id="EXAMPLES">EXAMPLES</h2>
<p>The following command:</p>
<pre><code> $ dijkstra US_airports.net 0
0 4784 5662 6603 11097 7470 4472 ....
$
</code></pre>
<p>will show on output the distances between node 0 and all the other
nodes in the graph <code>US_airports.net</code> (the US air transportation
network).</p>
