The Grundy number Γ ( G) is the largest k such that G has a greedy k -colouring. Easily, χ ( G )≤ Γ ( G )≤ Δ ( G )+1. Zaker [ 6] showed that for any fixed k, one can decide in polynomial time whether a given graph has Grundy number at most k.

In the study of graph coloring problems in mathematics and computer science, a greedy coloring or sequential coloring is a coloring of the vertices of a graph formed by a greedy algorithm that considers the vertices of the graph in sequence and assigns each vertex its first available color. Greedy colorings … See more The greedy coloring for a given vertex ordering can be computed by an algorithm that runs in linear time. The algorithm processes the vertices in the given ordering, assigning a color to each one as it is processed. The … See more It is possible to define variations of the greedy coloring algorithm in which the vertices of the given graph are colored in a given sequence but in which the color chosen for each vertex is not necessarily the first available color.
