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. WebMathmatically, a proper vertex coloring of an undirected graph G= (V,E) is a map c: V -> S such that c (u) != c (v) whenever there exists an edge (u,v) in G. The elements of set S are called the available colors. The problem is often to determine the minimum cardinality (the number of colors) of S for a given graph G or to ask whether it is ...
