Web'standard' – Computes the diameter of the input (di)graph as the largest eccentricity of its vertices. This is the classical algorithm with time complexity in \(O(nm)\). '2sweep' – Computes a lower bound on the diameter of an unweighted undirected graph using 2 BFS, as proposed in [MLH2008]. Webn, where m and s are the orders of the star graph and the path respectively. Obtaining the radio number of a graph is a rigorous process, which is dependent on diameter of G and positive di erence of non-negative integer labels f(u) and f(v) assigned to any two u;v in the vertex set V (G) of G.
