Scale-free graphs generated following the Barabási-Albert method, then selected for induced width. The weights of the constraint arcs are set such that at least one solution exists (i.e. the graph contains no negative cycles and the STN is consistent). This archive contains 426 graphs on 100–200 nodes, 460–891 arcs, upper bound on treewidth 38–58.
