<p class="short-description">The Structures_Graph_Manipulator_AcyclicTest is a graph manipulator which tests whether a graph contains a cycle.</p>
<p class="description"><p>The definition of an acyclic graph used in this manipulator is that of a DAG. The graph must be directed, or else it is considered cyclic, even when there are no arcs.</p></p>
