+\begin{problem}[Zenklusen ORL'14]
+Let $G=(V,E)$ be a graph with edge capacity $c:E\to\mathbb{Z}_+$ and edge removal costs $w:E\to\mathbb{Z}_+$ and let $B\in \mathbb Z_+$ be the budget.
+
+Find $F\subset E$ with $w(F)\leq B$ s.t. the min-cut in $G-F$ is minimized.
+\end{problem}

+connectivity interdiction $\approx$ min-cut + knapsack
+
+Is there an FPTAS?
