Center node: "the parameterized complexity of finding secluded solutions to some classical optimization problems on graphs"
  Abstract: Abstract   This work studies the parameterized complexity of finding secluded solutions to classical combinatorial optimization problems on graphs such as finding minimum    s   -   t    separators, feedback vertex sets, dominating sets, maximum independent sets, and vertex Herein, one searches not only to minimize or maximize the size of the solution, but also to minimize the size of its neighborhood. This restriction has applications in secure routing and community detection.
