1695.0. "Steiner Tree Algorithm?" by CX3PT2::KOWTOW::J_MARSH () Mon Nov 30 1992 16:30

    Can someone point me to an algorithm for finding the Steiner tree for a
    collection of points?  A Steiner tree is the tree connecting all points
    that minimizes the total length of all the branches, but you're allowed
    to add points to make the length smaller.

    I know this is one of those difficult problems (NP-hard?) and it is
    impractical to try to compute the Steiner tree for many points.  I'm
    looking for an algorithm that will work for a small number of points
    (4, 5, or 6) and it is OK if the algorithm fails for certain unusual
    sets of points.  Thanks...
