| Social network analysis frequently uses the idea of a clique in a network to identify key subgroups of highly-connected members of the network. We formulate the maximum clique problem on undirected graphs and develop two algorithms to solve it: a pruning algorithm and an enumeration algorithm. The pruning algorithm successively improves an upper bound on the clique number of a graph, and the enumeration algorithm successively finds larger and larger ... |

| In the network diversion problem (NDP), we must find a minimum-weight set of edges in a directed graph G=(V,E) whose deletion forces all s-t communication to pass through one or more diversion edges in a diversion set E(D). We develop and test a specialized branch-and-hound algorithm for this NP- complete problem. The algorithm is based on partitioning the solution space with respect to edges in certain s-t cuts and yields ... |
