WebAug 2, 2024 · In a directed graph, like a DAG, edges are "one-way streets", and reachability does not have to be symmetrical. Reachability is also affected by the fact that DAGs are acyclic. In an acyclic graph, reachability can be defined by a partial order. A partial order is a lesser group of nodes within a set that can still define the overall ...
