Polynomialtime approximation schemes for the Euclidean survivable network design problem
(2002) 29th International Colloquium, ICALP 2002 In Automata, Languages and Programming / Lecture Notes in Computer Science 2380. p.973984 Abstract
 The survivable network design problem is a classical problem in combinatorial optimization of constructing a minimumcost subgraph satisfying predetermined connectivity requirements. In this paper we consider its geometric version in which the input is a complete Euclidean graph. We assume that each vertex v has been assigned a connectivity requirement r(upsilon).. The output subgraph is supposed to have the vertex (or edge, respectively) connectivity of at least min{r(upsilon), r(u)} for any pair of vertices upsilon, u. We present the first polynomialtime approximation schemes (PTAS) for basic variants of the survivable network design problem in Euclidean graphs.

 The survivable network design problem is a classical problem in combinatorial optimization of constructing a minimumcost subgraph satisfying predetermined connectivity requirements. In this paper we consider its geometric version in which the input is a complete Euclidean graph. We assume that each vertex v has been assigned a connectivity requirement r(upsilon).. The output subgraph is supposed to have the vertex (or edge, respectively) connectivity of at least min{r(upsilon), r(u)} for any pair of vertices upsilon, u. We present the first polynomialtime approximation schemes (PTAS) for basic variants of the survivable network design problem in Euclidean graphs. We first show a PTAS for the Steiner tree problem, which is the survivable network design problem with r(upsilon) is an element of {0, 1} for any vertex upsilon. Then, we extend it to include the most widely applied case where r(upsilon) is an element of {0, 1, 2} for any vertex upsilon. Our polynomialtime approximation schemes work for both vertex and edgeconnectivity requirements in time 0 (n log n), where the constants depend on the dimension and the accuracy of approximation. Finally, we observe that our techniques yield also a PTAS for the multigraph variant of the problem where the edgeconnectivity requirements satisfy r(upsilon) is an element of {0, 1,..., k} and k = O(1).
