    On greedy heuristics for steiner minimum trees (1995)
    Springer
    Algorithmica 13 (1995), S. 381-386 
    Details
    ISSN: 1432-0541
    Keywords: Steiner trees ; Greed heuristic
    Source: Springer Online Journal Archives 1860-2000
    Topics: Computer Science , Mathematics
    Notes: Abstract We disprove a conjecture of Shor and Smith on a greedy heuristic for the Steiner minimum tree by showing that the length ratio between the Steiner minimum tree and the greedy tree constructed by their method for the same set of points can be arbitrarily close to√3/2. We also propose a new conjecture.
