限制3-碰集问题的线性核化

Linear Kernelizations for Restricted 3-Hitting Set Problems

Xuan Cai

摘要:

3- \textsc{Hitting Set}问题也称为3-一致超图上的\textsc{Vertex Cover}问题。本文研究了3-一致超图上的\textsc{Vertex Cover}问题的核化。我们证明了这一问题在三类3-一致超图中存在线性核。我们还得到了上下界的核大小的参数对偶。

英文摘要:

The 3-\textsc{Hitting Set} problem is also called the \textsc{Vertex Cover} problem on 3-uniform hypergraphs. In this paper, we address kernelizations of the \textsc{Vertex Cover} problem on 3-uniform hypergraphs. We show that this problem admits a linear kernel in three classes of 3-uniform hypergraphs. We also obtain lower and upper bounds on the kernel size for them by the parametric duality.
