Notes:

AG-Monien Graph Collection, Ralf Diekmann and Robert Preis http://www2.cs.uni-paderborn.de/fachbereich/AG/monien/RESEARCH/PART/graphs.html 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: bfly: 10 butterfly graphs 3..12 cage: 45 cage graphs 3..12 cca: 10 cube-connected cycle graphs, no wrap ccc: 10 cube-connected cycle graphs, with wrap debr: 18 De Bruijn graphs se: 13 shuffle-exchange graphs 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: 1 : CCA3 : 24 nodes 28 edges 56 nonzeros 2 : CCA4 : 64 nodes 80 edges 160 nonzeros 3 : CCA5 : 160 nodes 208 edges 416 nonzeros 4 : CCA6 : 384 nodes 512 edges 1024 nonzeros 5 : CCA7 : 896 nodes 1216 edges 2432 nonzeros 6 : CCA8 : 2048 nodes 2816 edges 5632 nonzeros 7 : CCA9 : 4608 nodes 6400 edges 12800 nonzeros 8 : CCA10 : 10240 nodes 14336 edges 28672 nonzeros 9 : CCA11 : 22528 nodes 31744 edges 63488 nonzeros 10 : CCA12 : 49152 nodes 69632 edges 139264 nonzeros The primary graph (Problem.A) in this sequence is the last graph in the sequence.
