WebThe diameter of a graph is defined as max v ∈ V ϵ ( v), where ϵ ( v) is the eccentricity of vertex v. In other words, this method computes the 'longest shortest path'. Two special cases exist. If the graph has no vertices, the diameter is 0. If the graph is disconnected, the diameter is Double.POSITIVE_INFINITY.
