Abstract

Many graph parameters are the optimal value of an objective function over selected subsets S of vertices with some constraint on how many selected neighbors vertices in S, and vertices not in S, can have. Classic examples are minimum dominating set and maximum independent set. We give a characterization of these graph parameters that unifies their definitions, facilitates their common algorithmic treatment and allows for their uniform complexity classification. This characterization provides the basis for a taxonomy of domination-type and independence-type problems. We investigate the computational complexity of problems within this taxonomy, identify classes of NP-complete problems and classes of problems solvable in polynomial time.
