Graph coloring is one of the most important concepts in graph theory. In the complete graph, each vertex is adjacent to remaining (n – 1) vertices. Similarly, the other regions are also coloured based on the adjacency. The regions ‘aeb’ and ‘befc’ are adjacent, as there is a common edge ‘be’ between those two regions. Two regions are said to be adjacent if they have a common edge. Region coloring is an assignment of colors to the regions of a planar graph such that no two adjacent regions have the same color. Note − A graph ‘G’ is said to be n-coverable if there is a vertex coloring that uses at most n colors, i.e., X(G) ≤ n.

Many algorithms exist for graph coloring on a single GPU or in distributed memory, but to the best of our knowledge, hybrid MPI+GPU algorithms have been unexplored until this work. If 'G' is not a null graph, then χ(G) ≥ 2. Abstract: Graph coloring is often used in parallelizing scientific computations that run in distributed and multi-GPU environments it identifies sets of independent data that can be updated in parallel. Χ(G) = 1 if and only if 'G' is a null graph. The minimum number of colors required for vertex coloring of graph ‘G’ is called as the chromatic number of G, denoted by X(G). Pengertian Algoritma ( Sorting secara paralel, Searching secara paralel, Paralel Graph algorithm, paralel Programmimg palatform). Simply put, no two vertices of an edge should be of the same color. Vertex coloring is an assignment of colors to the vertices of a graph ‘G’ such that no two adjacent vertices have the same color. Thus, the vertices or regions having same colors form independent sets. A coloring is given to a vertex or a particular region. While graph coloring, the constraints that are set on the graph are colors, order of coloring, the way of assigning color, etc.

For instance, we can answer the questions of not assigning the same resources dependent on each other at the same time. You can do vertex coloring, edge coloring, Geographic Map coloring, and different questions you can ask in this algorithm. There are many ways of graph coloring problems. This number is called the chromatic number and the graph is called a properly colored graph. Therefore, this article will briefly talk about its algorithm, and use cases of Graph Coloring.

In a graph, no two adjacent vertices, adjacent edges, or adjacent regions are colored with minimum number of colors. Ffi*, a APr*offi2on rttrift: W*c.Graph coloring is nothing but a simple way of labelling graph components such as vertices, edges, and regions under some constraints.
