The paper is concerned with the polynomial time approximability of node-deletion problems for hereditary properties. It is observed that, when such a property derives a matroid on any graph, the problem can be formulated as a matroid set cover optimization problem, and this leads us naturally to con
A k-separator k-shredder of a k-node connected undirected graph is a set of k Ε½ . nodes whose removal results in two or more three or more connected components. Let n denote the number of nodes. Solving an open question, we show that the problem of counting the number of k-separators is ΰ »P-complete.
