網頁The Steiner Tree problem has appeared in the Karp’s list of the first 21 NP-hard problems and is well known as one of the most fundamental problems in Network Design area. We study the Node-Weighted version of the Prize Collecting Steiner Tree problem. In this problem, we are given a simple graph with a cost and penalty value associated with ... 網頁A Steiner Tree is an undirected, weighted graph with a minimum-weight tree that connects a selected set of vertices, called terminals. Steiner vertices: The tree may include non …
Steiner tree for three points A, B, and C (note there are no direct connections between A, B, C). The Steiner point S is located at the Fermat point of the triangle ABC. Solution for four points—there are two Steiner points, S1 and S2 In combinatorial mathematics, the Steiner tree problem, or minimum Steiner … 查看更多內容 In combinatorial mathematics, the Steiner tree problem, or minimum Steiner tree problem, named after Jakob Steiner, is an umbrella term for a class of problems in combinatorial optimization. While Steiner tree problems … 查看更多內容 The rectilinear Steiner tree problem is a variant of the geometric Steiner tree problem in the plane, in which the Euclidean distance is replaced with the rectilinear distance. … 查看更多內容 The general graph Steiner tree problem can be approximated by computing the minimum spanning tree of the subgraph of the metric closure of the graph induced by the terminal vertices, as first published in 1981 by Kou et al. The metric closure of a graph G is the … 查看更多內容 The Steiner ratio is the supremum of the ratio of the total length of the minimum spanning tree to the minimum Steiner tree for a set of … 查看更多內容 The original problem was stated in the form that has become known as the Euclidean Steiner tree problem or geometric … 查看更多內容 Steiner trees have been extensively studied in the context of weighted graphs. The prototype is, arguably, the Steiner tree problem in graphs.
