Free Graph Coloring Algorithm Pseudo-Code. Since d is maximum degree, a vertex cannot be attached to more than d vertices. To color this vertex, we need to pick the smallest numbered color that is not used by the adjacent.

To color this vertex, we need to pick the smallest numbered color that is not used by the adjacent. When we color a vertex, at most dcolors could have already been used by its adjacent. Here d is the maximum degree in the given graph.
Here d is the maximum degree in the given graph. Since d is maximum degree, a vertex cannot be attached to more than d vertices. To color this vertex, we need to pick the smallest numbered color that is not used by the adjacent.
