稳定集与无偶洞图

Stable Sets and Graphs with no Even Holes

Michele Conforti, Bert Gerards, Kanstantsin Pashkovich

摘要:

我们开发的分解/组合工具,有效地解决最大权重稳定集的问题,以及描述它们作为多项式大小的线性规划(使用“紧凑的系统”)。其中一些是众所周知的,但需要一些额外的工作,以产生多项式“分解方案”。我们将这些工具应用于没有偶孔和帽的图。孔是长度大于大于3的无弦循环,并且帽是孔连同与孔的两个相邻节点相邻并且在孔上没有其他相邻节点的附加节点。

英文摘要:

We develop decomposition/composition tools for efficiently solving maximum weight stable sets problems as well as for describing them as polynomially sized linear programs (using "compact systems"). Some of these are well-known but need some extra work to yield polynomial "decomposition schemes". We apply the tools to graphs with no even hole and no cap. A hole is a chordless cycle of length greater than three and a cap is a hole together with an additional node that is adjacent to two adjacent nodes of the hole and that has no other neighbors on the hole.
