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.

2023年6月6日 · The Steiner Tree Problem involves finding the minimum-cost tree that spans a set of given vertices in an undirected, edge-weighted graph. This problem is known to be NP-hard, …

斯坦纳树问题是组合优化问题，与最小生成树相似，是最短网络的一种。 最小生成树是在给定的点集和边中寻求最短网络使所有点连通。 而最小斯坦纳树允许在给定点外增加额外的点，使生 …

2019年9月15日 · Given an undirected graph with non-negative edge weights and a subset of vertices (terminals), the Steiner Tree in graph is an MST “T” of minimum weight that contains …

In this lecture we give an algorithm for Steiner tree and then discuss greedy algorithms. 2.1 Steiner Tree Problem Statement: Given a weighted graph G = (V,E) and a set R ⊆ V, our goal …

Steiner Trees and Forests 1 Steiner Tree Problem Given an undirected graph G <V;EA, a cost function c E Q , and a partition of V into two sets R and S, flnd a minimum cost tree in G that …

The Steiner tree of some subset of the vertices of a graph G is a minimum-weight connected subgraph of G that includes all the vertices. It is always a tree. Steiner trees have practical …
