The -ary -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 -ary -cube. For any and , we show that the -ary -cube admits a Hamiltonian cycle passing through a linear forest with at most edges.
Highlights
► The -ary -cube admits a Hamiltonian cycle passing through a prescribed linear forest. ► The number of edges in the prescribed linear forest does not exceed . ► This generalized Dvor˘ák’s results.
