The algorithm combines an original crossover based on the notion of union of independent sets and a powerful local search operator tabu search. Graph coloring is a well known problem from graph theory that when attacking it with local search algorithms is typically treated as a series of constraint satisfaction problems. A hypothesis was experimentally. Tabucol is a local search algorithm to determine whether the vertices of an undi-rected graph can be colored with k colors such that no two vertices connected by an edge have the same color. GCP is very important because it has many applications.
