In graph theory, a directed graph may contain directed cycles, a one-way loop of edges. In some applications, such cycles are undesirable, and we wish to eliminate them and obtain a directed acyclic graph (DAG).
I am wondering how this is done. Given a graph such as this:
a -> b b -> c c -> d d -> a
Or a for loop flattened out such as:
somemethod -> forloop start forloop start -> forloop next forloop next -> forloop result forloop next -> forloop next // i+1 forloop next -> forloop end forloop end -> forloop result forloop result -> next method
Wondering how you can possibly remove the cycles from a graph like that.
