planarity - The Edge Addition Planarity Suite

       Determine which algorithm implementation to run

       -p     Planar embedding and Kuratowski subgraph isolation

       -d     Planar graph drawing by visibility representation

       -o     Outerplanar embedding and obstruction isolation

       -2     Search for subgraph homeomorphic to K_{2,3}

       -3     Search for subgraph homeomorphic to K_{3,3}

       -4     Search for subgraph homeomorphic to K_4

       -a     All of the above

       Invokes the Edge Addition Planarity Suite commandline tool.

       Without argument, the tool presents a menu-driven interactive interface.

       When used in batch mode, the tool returns 0 for a planar graph, 1 for a nonplanar graph and -1 on error.

planarity-s-q-pinfile.txtembedding.out[obstruction.out]
              Process infile.txt in quiet mode (-q), putting planar embedding in embedding.out or (optionally) a
              Kuratowski subgraph in Obstruction.out Process returns 0=planar, 1=nonplanar, -1=error

       planarity-s-q-dinfile.txtembedding.out[drawing.out]
              If graph in infile.txt is planar, then put embedding in embedding.out and  (optionally)  an  ASCII
              art drawing in drawing.out Process returns 0=planar, 1=nonplanar, -1=error

       Features in batch mode.

       -rCKN
              Run the C command (see below) on K random graphs with N vertices

       -sCIO[O2]
              Run  the  C  command (see below) on a specific graph given in the I input file, with output in the
              primary O file and complementary information in the secondary O2 file.

       -rmNO[O2]
              Compute a maximal planar random graph on N  vertices  with  output  in  the  primary  O  file  and
              optionally the chosen graph in the O2 file.

       -rnNO[O2]
              Compute  a  nonplanar  random  graph (maximal planar and an edge) on N vertices with output in the
              primary O file and optionally the chosen graph in the O2 file.
