In this paper, we present a number of network-analysis algorithms in the external-memory model. We focus on methods for large naturally sparse graphs, that is, n-vertex graphs that have O(n) edges and are structured so that this sparsity property holds for any subgraph of such a graph. We give efficient external-memory algorithms for the following problems for such graphs:

  1. 1

    Finding an approximate d-degeneracy ordering.

  2. 2

    Finding a cycle of length exactly c.

  3. 3

    Enumerating all maximal cliques.

Such problems are of interest, for example, in the analysis of social networks, where they are used to study network cohesion.
