Webweights are one. Steiner trees are important in various applications such as VLSI routings [32], phylogenetic tree reconstruction [31] and network routing [34]. We refer to the book of Pr¨omel and Steger [38] for an overview of the results and applications of the Steiner tree problem. The Steiner tree problem is known to be NP-hard [26].
