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. WebMathmatically, a proper vertex coloring of an undirected graph G= (V,E) is a map c: V -> S such that c (u) != c (v) whenever there exists an edge (u,v) in G. The elements of set S are called the available colors. The problem is often to determine the minimum cardinality (the number of colors) of S for a given graph G or to ask whether it is ...
