WebJul 27, 2014 · Graph coloring is computationally hard and it has been a research topic for many years. Most of the algorithms can be broadly categorized in one of two main topics “Contraction” and “Greedy Coloring”. Greedy Coloring focuses on carefully picking the next vertex to be colored. Once a vertex is colored, its color never changes. 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 ...
