A note on the generalized steiner tree polytope ( Juan Jos
نویسنده
چکیده
The generalized steiner tree problem (GSTP) is a variant of the classical Steiner tree problem (STP), in which a family of node clusters is given and the tree must span at one node for each cluster. This note introduces a lifting procedure for obtaining polyhedral information on GSTP from polyhedral results of STP. New classes of facet-de ning inequalities are presented. ? 2000 Elsevier Science B.V. All rights reserved.

The connected facility location polytope
We analyze the polytope associated with a combinatorial problem that combines the Steiner tree problem and the uncapacitated facility location problem. The problem, called connected facility location problem, is motivated by a real-world application in the design of a telecommunication network, and concerns with deciding the facilities to open, the assignment of customers to open facilities, an...
متن کاملOn the Asymmetric Connected Facility Location Polytope
This paper is concerned with the connected facility location problem, which has been intensively studied in the literature. The underlying polytopes, however, have not been investigated. This work is devoted to the polytope associated with the asymmetric version of the problem. We first lift known facets of the related Steiner arborescence and of the facility location polytope. Then we describe...
متن کاملThe Steiner tree polytope and related polyhedra
We consider the vertex-weighted version of the undirected Steiner tree problem. In this problem, a cost is incurred both for the vertices and the edges present in the Steiner tree. We completely describe the associated polytope by linear inequalities when the underlying graph is series-parallel. For general graphs, this formulation can be interpreted as a (partial) extended formulation for the ...
متن کاملGeodesic Spanners on Polyhedral Surfaces
In this paper we consider the problem of efficiently constructing geodesic t-spanners. We consider finding spanners on the surface of a 3 dimensional polyhedron. If Steiner vertices are allowed on the surface of the polyhedron, then we are able to construct sparse t-spanners. If no Steiner vertices are allowed, then we establish lower bounds on the maximum node degree, depending on the spanning...
متن کاملSolving a tri-objective convergent product network using the Steiner tree
Considering convergent product as an important manufacturing technology for digital products, we integrate functions and sub-functions using a comprehensive fuzzy mathematical optimization process. To form the convergent product, a web-based fuzzy network is considered in which a collection of base functions and sub-functions configure the nodes and each arc in the network is to be a link betwe...
