Webwhen coloring a vertex. We call this a greedy choice. The notion of a greedy algorithm is covered in JavaHyperText. Our algorithm, then, is: Color the vertices one by one, as follows: To color a vertex, choose the smallest color that is not already the color of a neighbor. We use this algorithm to color the graph that appears to the right.
