Checks if a graph is planar and returns the coloring of the graph
Arguments
- arcSources
Vector corresponding to the source nodes of a graph's edges
- arcTargets
Vector corresponding to the destination nodes of a graph's edges
- numNodes
The number of nodes in the graph
- algorithm,
the algorithm to use. "sixColoring" generates a 6-coloring of the graph, while "fiveColoring" generates a 5-coloring. Default is "fiveColoring".
Value
A named list containing 1) "is_planar": a logical if the
graph is planar, 2) "colors": the color of each vertex of the graph
