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.
