The neighbor rupture degree of a noncomplete connected graph G is defined to be (Equation presented) where S is any vertex subversion strategy of G, w(G/S) is the number of connected components in G/S, and c(G/S) is the maximum order of the components of G/S. In this study, the neighbor rupture degree of transformation graphs G-, G+-, G-+- and G++- of path graphs, cycle graphs, wheel graphs, complete graphs and complete bipartite graphs are obtained. © 2017 World Scientific Publishing Company.Article10.1142/S0129054117500216
