nauty-planarg1
Test graphs for planarity and find embeddings or obstructions
Usage
planarg [-v]
[-nVq]
[{-p | -u}]
[infile
[outfile]]
Overview
|
For each input, write to output if planar. |
|
|
The output file has a header if and only if the input file does. |
-
-v -
Write non-planar graphs instead of planar graphs
-
-V -
Write report on every input
-
-u -
Don't write anything, just count
-
-p -
Write in planar_code if planar (without
-p, same format as input)
-
-P -
Like
-pbut big-endian (same for <= 255 vertices)
-
-k -
Follow each non-planar output with an obstruction in sparse6 format (implies
-v, incompatible with-p)
-
-n -
Suppress checking of the result
-
-q -
Suppress auxiliary information
-
This program permits multiple edges and loops
