Abstract

The k-ary n-cube is one of the most popular interconnection networks for parallel and distributed systems. A linear forest in a graph is a subgraph, each component of which is a path. In this paper, we investigate the existence of Hamiltonian cycles passing through linear forests in the k-ary n-cube. For any n2 and k3, we show that the k-ary n-cube admits a Hamiltonian cycle passing through a linear forest with at most 2n1 edges.

Highlights

► The k-ary n-cube admits a Hamiltonian cycle passing through a prescribed linear forest. ► The number of edges in the prescribed linear forest does not exceed 2n1. ► This generalized Dvor˘ák’s results.
