    AG-Monien Graph Collection, Ralf Diekmann and Robert Preis                
    A collection of test graphs from various sources.  Many of the graphs          
    include XY or XYZ coordinates.  This set also includes some graphs from        
    the Harwell-Boeing collection, the NASA matrices, and some random matrices     
    which are not included here in the AG-Monien/ group of the UF Collection.      
    In addition, two graphs already appear in other groups:                        
       AG-Monien/big : same as Nasa/barth5, Pothen/barth5 (not included here)      
       AG-Monien/cage_3_11 : same as Pajek/GD98_c (included here)                  
    The AG-Monien/GRID subset is not included.  It contains square grids that      
    are already well-represented in the UF Collection.                             
    Six of the problem sets are included as sequences, each sequence being         
    a single problem instance in the UF Collection:

    Problem.aux.G{:} are the graphs in these 6 sequences.  Problem.aux.Gname{:}    
    are the original names of each graph, and Problemm.aux.Gcoord{:} are the       
    xy or xyz coordinates of each node, if present.                                
    Graphs in the cca sequence:

    The primary graph (Problem.A) in this sequence is the last graph               
    in the sequence.
