Given a power grid modeled by a network together with equations describing the power flows, power generation and consumption, and the laws of physics, the so-called N - k problem asks whether there exists a set of k or fewer arcs whose removal will cause the system to fail. We present theoretical results and computation involving two optimization algorithms for this problem.
