A 2-approximation for Minimum Cost {0, 1, 2} Vertex Connectivity - Fleischer (2001)   (Correct)

....times. In our case, this would be at most twice. In fact, the problem appears to be only harder when we are restricted to selecting an edge at most once. We give the linear programming formulation below. The constraints are based on a theorem of Menger. For multiple proofs and references, see [4]) Theorem I (Menger) Let G = V,E) be a graph, and s,t V such that (s, t) E. Then, the minimum number of vertices separating s from t in G is equal to the maximum number of vertex disjoint paths from s to t in G. For any subset C V, and disjoint set of vertices A C V , we express the ....

An Iterative Rounding 2-Approximation Algorithm for the Element.. - Fleischer (2001)   (4 citations)  (Correct)

....graph obtained from by removing all edges and vertices in , and all edges in . We say that separates are not in the same connected component of X . The constraints of our integer program are based on a theorem of Menger (for multiple proofs and references, see [5]) Theorem 3.1 (Menger) Let h be a graph, and d of vertices separating from in is equal to the maximum number of vertex disjoint paths from to in . Corollary 3.2 Let be a graph, with of elements in separating is equal to the ....
