zero or or more options as specified below
Specifies whether directed edges should be permitted in the graph returned. If true, the result will be a directed graph if the input was directed. The default value, false, produces an undirected graph.
Specifies whether edge weights should be included in the graph returned. If true, the result will be a weighted graph if the input was weighted. The default value, false, produces an unweighted graph.
The UnderlyingGraph(G,opts) command returns an underlying graph of a graph.
The default behavior produces a graph in which the directions of arcs and the weights of the edges (or arcs) have been dropped.
Note that UnderlyingGraph(G) = Graph(Vertices(G), Neighbors(G)).
G ≔ Digraph⁡1,2,2,3,3,4,4,1
G≔Graph 1: a directed unweighted graph with 4 vertices and 4 arc(s)
H ≔ UnderlyingGraph⁡G:
The GraphTheory[UnderlyingGraph] command was updated in Maple 2019.
The directed and weights options were introduced in Maple 2019.
