具有条件边故障的平衡超立方体中的无故障哈密顿圈

Fault-free Hamiltonian cycles in balanced hypercube with conditional edge faults

Pingshan Li, Min Xu

摘要:

平衡超立方体,$BH_n$,是超立方体$Q_n$的变体。Zhou et al. [Inform. Sci. 300(2015)20-27]提出了一个有趣的问题,即在$BH_n$中是否存在每个顶点与至少两个无故障边关联的无故障哈密顿圈。在本文中,我们考虑这个问题,并表明,每个无故障的边缘在于一个无故障的哈密顿圈在$BH_n$后,不超过$4n-5$故障的边缘发生,如果每个顶点是事件与至少两个无故障的边缘,所有$n\ge 2$。我们的结果是最佳的容忍边缘故障的最大数量。

英文摘要:

The balanced hypercube, $BH_n$, is a variant of hypercube $Q_n$. Zhou et al. [Inform. Sci. 300 (2015) 20-27] proposed an interesting problem that whether there is a fault-free Hamiltonian cycle in $BH_n$ with each vertex incident to at least two fault-free edges. In this paper, we consider this problem and show that each fault-free edge lies on a fault-free Hamiltonian cycle in $BH_n$ after no more than $4n-5$ faulty edges occur if each vertex is incident with at least two fault-free edges for all $n\ge 2$. Our result is optimal with respect to the maximum number of tolerated edge faults.
