Abstract
The k-ary n-cube Q k n (n ⩾ 2 and k ⩾ 3) is one of the most popular interconnection networks. In this paper, we consider the problem of a faultfree Hamiltonian cycle passing through a prescribed linear forest (i.e., pairwise vertex-disjoint paths) in the 3-ary n-cube Q 3 n with faulty edges. The following result is obtained. Let E 0 (≠ ∅) be a linear forest and F (≠= ∅) be a set of faulty edges in Q 3 n such that E 0 ∩ F = ∅ and |E 0| + |F| ⩽ 2n − 2. Then all edges of E 0 lie on a Hamiltonian cycle in Q 3 n − F, and the upper bound 2n − 2 is sharp.
