Web1 Answer. The graphutil method will execute n times itself.It is in the c Loop,and c goes upto m . Now the c loop goes n times due to recursion (i.e. m^n) and recursion goes … WebFeb 20, 2024 · Thus, the graph coloring algorithm runs in exponential time. Planar Graphs. A graph is called planar if it can be drawn on a 2D plane such that no two edges cross each other. The graph coloring problem is a well-known problem of a planar graph. Planar and non-planar graphs are illustrated in Fig. (f) & Fig. (g)

The Welsh–Powell algorithm is just the greedy algorithm where the vertices are considered in order of decreasing degree. That it is O ( n 2) stems from the fact that it considers each edge once when assigning a colour to a vertex.
