compute topological order
acyclic directed graph
output = one of default or permutation
When output=permutation, returns a list of integers representing the permutation to Vertices(G) to obtain the topological order. When output=default, a list of the actual vertices is returned.
The TopologicSort command returns a linear ordering of vertices of an acyclic digraph that is consistent with the arcs of the digraph. This means a vertex u precedes a vertex v if there is an arc from u to v. The output is a list.
The GraphTheory[TopologicSort] command was updated in Maple 2021.
The output option was introduced in Maple 2021.
