The generalized 4-connectivity of folded hypercube

ABSTRACT In recent years, a growing number of concepts have been proposed to better assess network fault tolerance, among which the generalized -connectivity has been widely used in the research of fault tolerance of interconnection networks. For connected graph , refers to the maximum number of internally disjoint trees in to connect , where with . The generalized -connectivity of G . The -dimensional folded hypercube , as a hypercube-like network, is obtained by adding edges on -dimensional hypercube . In this paper, we discuss the generalized 4-connectivity of and show that for .
