WebFeb 26, 2024 · It is common to define a directed graph to be a pair ( V, E) where V is a set, called the vertices, and E ⊆ V × V is a set, called the edges (excluding ( v, v) for all v ∈ V ). A DAG is then a particular kind of directed graph (having no directed cycles). In particular, since E is a set, there is no way to express the fact that there are ...
