    Notes:

    DIMACS10 star-mixtures set                                           
                                                                         
    Each graph in this benchmark represents a star-like structure of     
    different graphs S0 , . . . , St. Graphs S1 , . . . , St are weakly  
    connected to the center S0 by random edges. The total number of edges
    between each Si and S0 was less than 3% out of the total number of   
    edges in Si . The graphs are mixtures of the following structures:   
    social networks, finite-element graphs, VLSI chips, peer-to-peer     
    networks, and matrices from optimization solvers.
