we implement the branch and bound algorithm to solve the graph coloring problem, in graph theory graph coloring is a special case of graph labeling it is an assignment of labels traditionally called colors to elements of a graph subject to certain constraints in its simplest form it is a way of coloring the vertices of a graph such that no two adjacent vertices are of the same color this is called a vertex coloring
