• Approximating Acyclicity Parameters of Sparse Hypergraphs 

      Fomin, Fedor; Golovach, Petr; Thilikos, Dimitrios (Conference object; Peer reviewed; Journal article, 2009)
      The notions of hypertree width and generalized hypertree width were introduced by Gottlob, Leone, and Scarcello (PODS'99, PODS'01) in order to extend the concept of hypergraph acyclicity. These notions were further generalized ...
    • Bidimensionality and Kernels 

      Fomin, Fedor; Lokshtanov, Daniel; Saurabh, Saket; Thilikos, Dimitrios (Journal article; Peer reviewed, 2020)
      Bidimensionality theory was introduced by [E. D. Demaine et al., J. ACM, 52 (2005), pp. 866--893] as a tool to obtain subexponential time parameterized algorithms on H-minor-free graphs. In [E. D. Demaine and M. Hajiaghayi, ...
    • Hitting Topological Minor Models in Planar Graphs is Fixed Parameter Tractable 

      Golovach, Petr; Thilikos, Dimitrios; Stamoulis, Giannos (Journal article; Peer reviewed, 2020)
      For a finite collection of graphs F, the F-TM-Deletion problem has as input an n-vertex graph G and an integer k and asks whether there exists a set S ⊆ V(G) with |S| ≤ k such that G \ S does not contain any of the graphs ...
