Abstract
Dominating Set is one of the most classical NP-complete combinatorial graph problems. Unfortunately, the natural parameterization (by solution size) does not make this problem feasible in the sense of Parameterized Complexity. We propose two new views to consider Dominating Set, and a new parameterization of this problem (by the profit parameter) and give algorithms for these parameterizations that show the problems to be in FPT. More precisely, we give a linear-size kernel and a search-tree procedure.

Note that below we also discuss the possibility replacing term \(\omega |N|\) by some function \(\omega :N\rightarrow [0,1]\) that assigns weights to vertices from N.
