Center node: "a subexponential parameterized algorithm for proper interval completion"
  Abstract: In the Proper Interval Completion problem we are given a graph G and an integer k, and the task is to turn G using at most k edge additions into a proper interval graph, i.e., a graph admitting an intersection model of equal-length intervals on a line. The study of Proper Interval Completion from the viewpoint of parameterized complexity has been initiated by Kaplan, Shamir and Tarjan [FOCS 1994; SIAM J. Comput. 1999], who showed an algorithm for the problem working in $O(16^k (n + m))$ time. In this paper we present an algorithm with running time $k^{O(k^{2/3})} + O(nm(kn + m))$, which is the first subexponential parameterized algorithm for Proper Interval Completion.
