WebAn instance of the G raph H-coloring problem consists of a finite graph G. The question is whether there is a homomorphism from G to H. When H is the complete graph on k vertices, the G raph H-coloring problem corresponds to the standard G raph C olorability problem with k colours (see Example 8.11). WebThe graph (or vertex) coloring problem, which involves assigning colors to vertices in a graph such that adjacenct vertices have distinct colors, arises in a number of scientific and engineering applications such as scheduling , register allocation , optimization and parallel numerical computation.
