    DIMACS10 set: clustering/G_n_pin_pout                               
    This graph has been generated using a two-level Gnp random-graph    
    generator.  First, each vertex chooses a cluster to belong to,      
    iid randomly. Then, in the spirit of the Erdos-Renyi model,         
    cluster-internal edges are created with a given internal            
    probability each, then cluster-external edges are created with a    
    smaller external probability each. The parameters for this          
    instance are: 100000 vertices, 316 clusters, the internal and       
    the external edge probability are chosen such that the expected     
    number of cluster-internal and the expected number of cluster-      
    external incidences of a node are both five. Such a graph is simple.
