WebParallel Graph Coloring with Cuda C++ Introduction. In general, graph coloring can refer to conditionally labelling any component of a graph such as its vertices or edges. We deal with a special case of graph coloring called "Vertex Coloring". The problem statement is as follows: An undirected graph G is a set of vertices V and a set of edges E. WebIn graph theory, Welsh Powell is used to implement graph labeling; it is an assignment of labels traditionally called "colors" to elements of a graph subject to certain constraints. In 1967 Welsh and Powell Algorithm introduced in an upper bound to the chromatic number of a graph . It provides a greedy algorithm that runs on a static graph.
