    DIMACS10 set: clustering/smallworld                               
    This graph has been generated using the small world generator of  
    the Boost Graph Library. Starting with a ring of 100000 vertices  
    and 500000 edges, edges are rewired with a probability of 0.2     
    according to the random model of Watts and Strogatz (see Watts and
    Strogatz, "Collective Dynamics of Small-World Networks", Nature,  
    1998). Multiple edges are removed after the process.
