Abstract

The balanced hypercube BHn, a variant of the hypercube, is a novel interconnection network for massive parallel systems. It is known that the balanced hypercube remains Hamiltonian after deleting at most 4n−5 faulty edges if each vertex is incident with at least two edges in the resulting graph for all n≥2. In this paper, we show that there still exists a Hamiltonian cycle in BHn for n≥2 after deleting a set F of edges with |F|≤5n−7 if the degree of every vertex in BHn−F is at least two and there exists no f4-cycles in BHn−F, which improves some known results.
