WebGraph Coloring Algorithm using Backtracking What is graph coloring problem? Graph coloring problem involves assigning colors to certain elements of a graph subject to certain restrictions and constraints. This has found applications in numerous fields in computer science. For example: WebIntroduction. To study graphs as mathematical structures, we use graph labeling. Graph labeling is a way of assigning labels to vertices, edges, or faces of a graph. It can be done in various ways. Graph coloring is one of the prime methods of labeling. It is a process of assigning labels or "colors" to elements of a graph following certain constraints. goat horns no backgroundWebNote: The graph coloring problem is also known as the vertex coloring problem.
