- * The network simplex algorithm assigns ranks to each node in the input graph

- *       edges in the tree have no slack (difference between length of edge
- *       and minlen for the edge). This by itself greatly improves the assigned
- *       rankings by shorting edges.
- *    3. Iteratively find edges that have negative cut values. Generally a
- *       negative cut value indicates that the edge could be removed and a new
- *       tree edge could be added to produce a more compact graph.
