Following is the basic Greedy Algorithm to assign colors. In graph theory graph coloring is an assignment of labels traditionally called colors to elements of a graph subject to certain constraints. A way of coloring the vertices of a graph such that no two. One of possible result would be. Graph coloring algorithms follow the approach of assigning colors to the elements present in the graph under certain conditions.
