An Introduction to Directed Acyclic Graphs (DAGs) for …

The reachability relation of a DAG can be formalized as a partial order ≤ on the vertices of the DAG. In this partial order, two vertices u and v are ordered as u ≤ v exactly when there exists a directed path from u to v in the DAG; that is, when u can reach v (or v is reachable from u). However, different DAGs may give rise to the same reachability relation and the same partial order. For example, a D… WebA straightforward algorithm for determining a valid topological ordering of a directed acyclic graph follows from the definition of topological ordering.
