 HighlightedVertices
 retrieve the highlighted vertices from a graph

 Calling Sequence HighlightedVertices( G )

Parameters

 G - graph

Description

 • The HighlightedVertices command returns a list (which may be empty) of the vertices of a graph G that have been highlighted.
 • A vertex is considered to have been highlighted if it is to be drawn with a color other than the default.

Examples

 > $\mathrm{with}\left(\mathrm{GraphTheory}\right):$
 > $G≔\mathrm{CompleteGraph}\left(5\right):$
 > $\mathrm{HighlightedVertices}\left(G\right)$
 $\left[\right]$ (1)
 > $\mathrm{HighlightVertex}\left(G,\left\{1,4\right\},"PaleGreen"\right)$
 > $\mathrm{HighlightedVertices}\left(G\right)$
 $\left[{1}{,}{4}\right]$ (2)
