SYNOPSIS

DESCRIPTION

14       Invokes the Edge Addition Planarity Suite commandline tool.
15
16       Without  argument,  the  tool presents a menu-driven interactive inter‐
17       face.
18
19       When used in batch mode, the tool returns 0 for a planar graph, 1 for a
20       nonplanar graph and -1 on error.

FEATURES

34       Features in batch mode.
35
36       -r C K N
37              Run the C command (see below) on K random graphs with N vertices
38
39       -s C I O [O2]
40              Run the C command (see below) on a specific graph given in the I
41              input file, with output in the primary O file and  complementary
42              information in the secondary O2 file.
43
44       -rm N O [O2]
45              Compute  a maximal planar random graph on N vertices with output
46              in the primary O file and optionally the chosen graph in the  O2
47              file.
48
49       -rn N O [O2]
50              Compute a nonplanar random graph (maximal planar and an edge) on
51              N vertices with output in the primary O file and optionally  the
52              chosen graph in the O2 file.

EXAMPLES

73       planarity -s -q -p infile.txt embedding.out [obstruction.out]
74              Process  infile.txt in quiet mode (-q), putting planar embedding
75              in  embedding.out  or  (optionally)  a  Kuratowski  subgraph  in
76              Obstruction.out Process returns 0=planar, 1=nonplanar, -1=error
77
78       planarity -s -q -d infile.txt embedding.out [drawing.out]
79              If  graph  in infile.txt is planar, then put embedding in embed‐
80              ding.out and (optionally) an ASCII art  drawing  in  drawing.out
81              Process returns 0=planar, 1=nonplanar, -1=error
