Hamiltonian Connectivity of Twisted Hypercube-Like Networks under the Large Fault Model

Abstract

Twisted hypercube-like networks (THLNs) are an important class of interconnection networks for parallel computing systems, which include most popular variants of the hypercubes, such as crossed cubes, M\"obius cubes, twisted cubes and locally twisted cubes. This paper deals with the fault-tolerant hamiltonian connectivity of THLNs under the large fault model. Let GG be an nn-dimensional THLN and FV(G)E(G)F \subseteq V(G)\bigcup E(G), where n7n \geq 7 and F2n10|F| \leq 2n - 10. We prove that for any two nodes u,vV(GF)u,v \in V(G - F) satisfying a simple necessary condition on neighbors of uu and vv, there exists a hamiltonian or near-hamiltonian path between uu and vv in GFG-F. The result extends further the fault-tolerant graph embedding capability of THLNs.
