圆弧图的有效完美控制

Efficient and Perfect domination on circular-arc graphs

Min Chih Lin, Michel J. Mizrahi, Jayme L. Szwarcfiter

摘要:

给定图$G = (V,E)$,\emph{perfect dominating set}是顶点$V' \subseteq V(G)$的子集,使得每个顶点$v \in V(G)\setminus V'$恰好由一个顶点$v' \in V'$支配。\emph{efficient dominating set}是完美支配集$V'$,其中$V'$也是独立集。这些问题通常用边而不是顶点来表示。这两个问题,无论是顶点或边的变种,仍然是NP-难的,即使限制到某些图形的家庭。我们研究这两个变种的圆弧图的问题,并显示有效的算法。

英文摘要:

Given a graph $G = (V,E)$, a \emph{perfect dominating set} is a subset of vertices $V' \subseteq V(G)$ such that each vertex $v \in V(G)\setminus V'$ is dominated by exactly one vertex $v' \in V'$. An \emph{efficient dominating set} is a perfect dominating set $V'$ where $V'$ is also an independent set. These problems are usually posed in terms of edges instead of vertices. Both problems, either for the vertex or edge variant, remains NP-Hard, even when restricted to certain graphs families. We study both variants of the problems for the circular-arc graphs, and show efficient algorithms for all of them.
