“…Since matching preclusion problem was proposed, it has been studied for many graphs, such as hypercube [3], k-ary n-cube [27], tori network [10], balanced hypercube [23], folded Petersen cube [5], cube-connected cycle [20] and pancake and burnt pancake graph [8,17]. Furthermore, there are also some papers studying matching preclusion for some classes of graph, such as bipartite graph [6,7], regular graph [9,21], vertex-transitive graph [19] and Cartesian product of graphs [10,21]. In complexity issue, M. Lacroix et al [18] showed that matching preclusion problem is NP-complete even for bipartite graphs.…”
