Graceful Labeling of Few Types of Graphs and Their Applications

Graph labeling is one of the most conspicuous research areas in graph theory and the history of graph labeling can be traced back to 1967. As well as graph labeling techniques are widely used in almost every field such as in the medical field, engineering field, military field, astronomical field, and many more. Graceful labeling is a bit more popular out of these graph labeling techniques since it has a wide range of applications in the real world. Some of them are in coding theory, X-ray crystallography, missile guiding codes, communication networks, cryptography, etc. In this study, we introduce graceful labeling of triangular-type grid graphs.
