永恒顶点覆盖数的一个新下界

A new lower bound for eternal vertex cover number

Jasine Babu, Veena Prabhakaran

摘要:

利用包含所有割点的$G$中最小顶点覆盖的基数,得到了任意图$G$的永恒顶点覆盖数的一个新的下界.下界的后果包括一个二次时间算法计算的永恒顶点覆盖数弦图。

英文摘要:

We obtain a new lower bound for the eternal vertex cover number of an arbitrary graph $G$, in terms of the cardinality of a vertex cover of minimum size in $G$ containing all its cut vertices. The consequences of the lower bound includes a quadratic time algorithm for computing the eternal vertex cover number of chordal graphs.
