WebGraph coloring problem is an NP-Complete problem. You are already getting a hint that we will do Graph coloring using the Greedy algorithm. The greedy algorithm doesn’t always use a minimum number of colors. … 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 color, using a vertex ordering chosen to use as many colors as possible. Grundy numbers are named after P. M. Grundy, w…
