<div id="content"><div id="content-area"><div id="article-title">floyd-warshall</div><div id="article"><dfn>floyd-warshall</dfn> is a (very) preliminary library for Floyd-Warshall all-pairs shortest-path <a href="algorithm.html" class="category">algorithm</a> computations on weighted directed <a href="Graph.html" class="category">Graph</a>s, written by <a href="Robert Goldman.html" class="internal">Robert Goldman</a>.<p>The interface aims to make it as generic as possible, so that one does not have to use special data structures to define one's graph edges, instead one provides a set of objects corresponding to graph roots and a function that, when applied to the object corresponding to a node, gives edge information. For those familiar with <a href="CLIM.html" class="internal">CLIM</a>'s <code>format-graph-from-roots</code>, the interface is somewhat similar.<p>This is my first shot at an <a href="asdf-install.html" class="category">asdf-install</a>able system, and the system is at a very early state (i.e., not at all optimized). On the other hand, this is an algorithm that I find myself regularly needing, so I felt it worth offering.<p>There is some <a href="ALBERT.html" class="internal">ALBERT</a>-generated HTML documentation included with the package (oddly, the key <code>all-shortest-paths</code> function doesn't appear on the main package page...).<p>Download: <a href="http://rpgoldman.real-time.com/lisp/floyd-warshall_0.02.tgz">http://rpgoldman.real-time.com/lisp/floyd-warshall_0.02.tgz</a><p>License: <a href="LLGPL.html" class="category">LLGPL</a></div></div>
