The contraction of the term "degree of saturation" forms the name of the algorithm. [2] DSatur is a heuristic graph colouring algorithm, yet produces exact results for bipartite, [1] cycle, and wheel graphs. [2] DSatur has also been referred to as saturation LF in the literature. [3]

Graph Coloring Page by Joseph Culberson (graph coloring programs) CoLoRaTiOn by Jim Andrews and Mike Fellows is a graph coloring puzzle
Chaitin's algorithm is a bottom-up, graph coloring register allocation algorithm that uses cost/degree as its spill metric. It is named after its designer, Gregory Chaitin . Chaitin's algorithm was the first register allocation algorithm that made use of coloring of the interference graph for both register allocations and spilling.
In the study of graph coloring problems in mathematics and computer science, a greedy coloring or sequential coloring [1] 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 can be found in linear time, but ...
In computer science and graph theory, the term color-coding refers to an algorithmic technique which is useful in the discovery of network motifs. For example, it can be used to detect a simple path of length k in a given graph. The traditional color-coding algorithm is probabilistic, but it can be derandomized without much overhead in the ...
The Misra & Gries edge coloring algorithm is a polynomial time algorithm in graph theory that finds an edge coloring of any simple graph. The coloring produced uses at most + colors, where is the maximum degree of the graph. This is optimal for some graphs, and it uses at most one color more than optimal for all others. The existence of such a ...
Finding ψ(G) is an optimization problem.The decision problem for complete coloring can be phrased as: . INSTANCE: a graph G = (V, E) and positive integer k QUESTION: does there exist a partition of V into k or more disjoint sets V 1, V 2, …, V k such that each V i is an independent set for G and such that for each pair of distinct sets V i, V j, V i ∪ V j is not an independent set.
Bodlaender & Fomin (2005) showed that, given a graph G and a number c of colors, it is possible to test whether G admits an equitable c-coloring in time O(n O(t)), where t is the treewidth of G; in particular, equitable coloring may be solved optimally in polynomial time for trees (previously known due to Chen & Lih 1994) and outerplanar graphs ...
