Three composite graphs Ladder graph (L_{n}), Tadpole graph (T_{n,k}) and Wheel graph (W_{n}) are graceful graphs, which have different applications in electrical, electronics, wireless communication etc. In this report, ...

Cordial labeling is one of the useful labeling in the realm of graph labeling. For the graph G=(V,E) vertex set V is label by {0,1}, where labeling of edge set E calculated by absolute difference between the end vertices ...
