Benchmark instances for experiments in "Computing all-pairs shortest paths by leveraging low treewidth" - Scale-free; constant vertex count, varying density (Figure 3)

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 190 graphs on 150 nodes, 296–2240 arcs, upper bound on treewidth 14–103.
