  - * <Explanation starting strategy here>
  + * There are two "starting strategies" currently available: minimum degree and
  + * pseudo-peripheral. These strategies control how a starting vertex for a
  + * connected component is choosen, which is then renumbered as first vertex in
  + * the component, starting the algorithm from there.
  + * In general, the bandwidths obtained by choosing a pseudo-peripheral node are
  + * slightly smaller than those obtained from choosing a node of minimum degree.
  + * On the other hand, this strategy is much more expensive, relatively.
