We consider new variants of the vertex/edge domination
problems on graphs. A vertex is said to {\em dominate} itself and its
all adjacent vertices, and similarly an edge is said to {\em dominate}
itself and its all adjacent edges. Given an input graph $G = (V, E)$
and an integer $k$, the {\sc $k$-Vertex ($k$-Edge) Maximum Domination}
({\sf $k$-MaxVD} and {\sf $k$-MaxED}, respectively) is to find a subset
$D_{V} \subseteq V$ of vertices (resp., $D_{E}\subseteq E$ of edges)
with size at most $k$ that maximizes the cardinality of dominated
vertices (resp., edges). In this paper, we first show that a simple
greedy strategy achieves an approximation ratio of $(1-1/e)$ for both
{\sf $k$-MaxVD} and {\sf $k$-MaxED}. Then, we show that this
approximation ratio is the best possible for {\sf $k$-MaxVD} unless
${\cal P} = {\cal NP}$. We also prove that, for any constant
$\varepsilon > 0$,
there is no polynomial time $1303/1304 + \varepsilon$ approximation
algorithm for {\sf $k$-MaxED} unless ${\cal P} = {\cal NP}$.
However, if $k$ is not larger than the size of the minimum maximal
matching, {\sf $k$-MaxED} is $3/4$-approximable in polynomial
time. |
