Let G be a connected graph, and let d(a, b) denotes the shortest path distance between vertices a and b of G. The graph G is δ-hyperbolic if for any vertices a, b, c, d of G, the two largest of the three sums S1 = d(a,b) + d(c,d), S2 = d(a,c) + d(b,d), and S3 = d(a,d) + d(b,c) differ by at most 2δ. This can be determined in time O(n^4) which could be prohibitive for large graphs. In this document, we propose an exact algorithm for determining the hyperbolicity of a graph that is scalable for large graphs. The time complexity of this algorithm is a function of the size of the largest bi-connected component of the graph, of the shortest path distance distribution in this component and of the value of the hyperbolicity. In the worst case, the ...
