Speeding up the Dreyfus–Wagner algorithm for minimum Steiner trees

Fuchs, Bernhard; Kern, Walter; Wang, Xinhui - In: Computational Statistics 66 (2007) 1, pp. 117-125

The Dreyfus–Wagner algorithm is a well-known dynamic programming method for computing minimum Steiner trees in general weighted graphs in time O * (3 k ), where k is the number of terminal nodes to be connected. We improve its running time to O * (2.684 k ) by showing that the optimum Steiner...
