Fixed-parameter tractability and lower bounds for stabbing problems
We study the following general stabbing problem from a parameterized complexity point of view: Given a set S of n translates of an object in R, find a set of k lines with the property that every object in S is ”stabbed” (intersected) by at least one line. We show that when S consists of axis-parallel unit squares in R the (decision) problem of stabbing S with axis-parallel lines is W[1]-hard wi...
متن کاملFixed Parameter Tractability and Treewidth 14 . 1 Fixed Parameter Tractability
One of the ways to cope with hard problems in practice is to realized that problem instances may be associated with some “parameters” related to their complexity. If the parameter of an instance is small, we might have some hope in finding a polynomial time solution to that instance. This idea has been investigated in the 1990’s by Downian and Fellowes in their work on fixed parameter tractabil...
متن کاملLower Bounds for Line Stabbing
We present an (n log n) xed order algebraic decision tree lower bound for determining the existence of a line stabber for a family of n line segments in the plane. We give the same lower bound for determining the existence of a line stabber for n translates of a circle in the plane. In proving this lower bound, we show that this problem is equivalent to determining if the width of a set of poin...
متن کاملFixed-Parameter Tractability of Graph Modification Problems for Hereditary Properties
This paper is concerned with the fixed-parameter tractability of the problem of deciding whether a graph can be made into a graph with a specified hereditary property by deleting at most i vertices, at most j edges, and adding at most k edges, where i, j, k are fixed integers. It is shown that this problem is fixed-parameter tractable whenever the hereditary property can be characterized by a f...
متن کاملFixed-Parameter Tractability Results for Feedback Set Problems in Tournaments
Complementing recent progress on classical complexity and polynomial-time approximability of feedback set problems in (bipartite) tournaments, we extend and partially improve fixed-parameter tractability results for these problems. We show that Feedback Vertex Set in tournaments is amenable to the novel iterative compression technique. Moreover, we provide data reductions and problem kernels fo...
