Frage 2
Frage
Select the correct definition.
Topological sorting:
Antworten
-
A) Given a cyclic digraph find a linear ordering of vertices such
that for all edges (v, w) in E, v procedes w in the ordering.
-
B) Given an acyclic undirected graph find a linear ordering of nodes
such that for all vertices (v, w) in E, v proceeds w in the ordering
-
C) Given an acyclic digraph find a quadratic ordering of nodes such
that for all edges (v, w) in E, v proceeds w in the ordering.
-
D) Given an acyclic digraph find a linear ordering of nodes such
that for all edges (v, w) in E, v proceeds w in the ordering.

Frage 15
Frage
Given this sudo-method:
list digraph::topoSort()
{
// make a copy of digraph G
// make a list l
// for each vertex in G
// select a vertex v with an outdegree of 2
// add v to the front of l
// delete v and it's edges from the digraph
}
What is the problem with this method?
