Class LargestDegreeFirstColoring<V,​E>

  • Type Parameters:
    V - the graph vertex type
    E - the graph edge type
    All Implemented Interfaces:

    public class LargestDegreeFirstColoring<V,​E>
    extends GreedyColoring<V,​E>
    The largest degree first greedy coloring algorithm.

    This is the greedy coloring algorithm which orders the vertices by non-increasing degree. See the following paper for details.
