NAME
planarity - The Edge Addition Planarity Suite
SYNOPSIS
planarity
[-q]
[-h|-help]
[-i|-info]
[-r]
[-s]
[-rm]
[-rn]
DESCRIPTION
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.
OPTIONS
- -q
-
Quiet mode
- -h, -help
-
Display some help
- -i, -info
-
Display copyright, license and reference articles information
FEATURES
Features in batch mode.
- -r C K N
-
Run the C command (see below) on K random graphs with N vertices
- -s C I O [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.
- -rm N O [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.
- -rn N O [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.
COMMANDS

- -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

EXAMPLES
- planarity -s -q -p infile.txt embedding.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 -d infile.txt embedding.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
