- This archive contains the collection of artificial graphs
- with known crossing numbers
- gml/ contains the graphs in GML file format
- Each directory contains subdirectories for the different kinds
- of graphs:
- Cm_x_Cn cross products of cycles
- Gi_x_Cn cross products of 5-vertex graphs with cycles
- Gi_x_Pn cross products of 5-vertex graphs with paths
- P(n,2) generalized Petersen graphs
- P(n,3) generalized Petersen graphs
- Each file name reflects the graph itself and its crossing number (_cnXX).
