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. WebMar 26, 2013 · Then (A k) ij is nonzero iff d (i, j) ≤ k.

Webin such graphs can be solved in O˜(nω) time – the best al-gorithm is by Zwick [36] running in O(n2.54) time [25], and hence for directed unweighted graphs diameter and radius can be solved somewhat faster than APSP. For undirected unweighted graphs the best known algorithm for diameter and radius is Seidel’s O˜(nω) time APSP algorithm [32].
