Abstract
We consider the problem introduced by Korach and Stern in [15] of building
a network given connectivity constraints. A network designer is given a set
of vertices V and constraints Si V , and seeks to build the lowest cost set of
edges E such that each Si induces a connected subgraph of (V, E). First, we
answer a question posed by Korach and Stern in [16]: for the offline version
of the problem, we prove an (log(n)) hardness of approximation result for
