考虑故障网络是有用的,因为网络中可能发生节点故障或链路故障。本文研究了条件故障超立方体的哈密顿性质。设F是n≥ 4的超立方体Qn中的故障边集,|F| ≤ 3 n− 11。证明了在满足以下两个条件的情况下,Qn-F中仍然存在连接不同分集的任意两个顶点的哈密尔顿路:(1)Qn-F中每个顶点的度至少为2;(2)Qn-F中至多有一个顶点的度为2.
It is useful to consider faulty networks because node faults or link faults may occur in networks. In this paper, we investigate hamiltonian properties of conditional faulty hypercubes. Let F be a set of faulty edges in hypercube Q n with n≥ 4 and| F|≤ 3 n− 11. We prove that there still exists a hamiltonian path in Q n− F joining any two vertices of different partite sets if the following two constraints are satisfied:(1) the degree of every vertex in Q n− F is at least 2, and (2) there is at most one vertex with degree 2 in Q n− F.
