Query: The $(2,k)$-connectivity augmentation problem: Algorithmic aspects   Durand de Gevigney and Szigeti \cite{DgGSz} have recently given a min-max
theorem for the $(2,k)$-connectivity augmentation problem. This article
provides an $O(n^3(m+ n \textrm{ }log\textrm{ }n))$ algorithm to find an
optimal solution for this problem.
