On the Grundy and b-chromatic numbers of a graph

WebThe numbers indicate the order in which the greedy algorithm colors the vertices. In graph theory, the Grundy number or Grundy chromatic number of an undirected graph is the maximum number of colors that can be used by a greedy coloring strategy that considers the vertices of the graph in sequence and assigns each vertex its first available ... WebOnline Graph Coloring Algorithm This first fit is a greedy approach in choosing the best color for a vertex that appears dynamically along its edges for a given graph. So, whenever a new vertex appears along with its edges, the new vertex is given a new color with first fit (i.e. the best possible minimum color), without altering the colors ...
