Parameterized Complexity of Generalized Domination Problems on Bounded Tree-Width Graphs
Clinical Orthopaedics and Related Research(2010)
摘要
The concept of generalized domination unifies well-known variants of
domination-like problems. A generalized domination (also called
[Sigma,Rho]-domination) problem consists in finding a dominating set for which
every vertex of the input graph is satisfied, given two sets of constraints
Sigma and Rho. Very few problems are known to be W[1]-hard when restricted to
graphs of bounded tree-width. We exhibit here a large new (infinite) collection
of W[1]-hard problems parameterized by the tree-width of the input graph, that
is [Sigma,Rho]-domination when Sigma is a set with arbitrary large gaps between
two consecutive elements and Rho is cofinite (and an additional technical
constraint on Sigma).
