WebJan 1, 2002 · A vertex coloring of graph G = (V, E) is an F: V→N mapping where adjacent vertex are different colors in N, i.e. if uv is in E, then F (u) is not equal to F (v) [11]. A graph G can be colored ... WebIntroduction. To study graphs as mathematical structures, we use graph labeling. Graph labeling is a way of assigning labels to vertices, edges, or faces of a graph. It can be done in various ways. Graph coloring is one of the prime methods of labeling. It is a process of assigning labels or "colors" to elements of a graph following certain constraints.
