In mathematics, particularly graph theory, and computer science, a directed acyclic graph (DAG) is a directed graph with no directed cycles. That is, it consists of vertices and edges (also called arcs), with each edge directed from one vertex to another, such that following those directions will never form a closed loop. A … See more A graph is formed by vertices and by edges connecting pairs of vertices, where the vertices can be any kind of object that is connected in pairs by edges. In the case of a directed graph, each edge has an orientation, from … See more Topological sorting and recognition Topological sorting is the algorithmic problem of finding a topological ordering of a given DAG. It can be solved in linear time. Kahn's algorithm … See more • Weisstein, Eric W., "Acyclic Digraph", MathWorld • DAGitty – an online tool for creating DAGs See more Reachability relation, transitive closure, and transitive reduction 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 … See more Scheduling Directed acyclic graph representations of partial orderings have many applications in scheduling for systems of tasks with ordering constraints. An important class of problems of this type concern collections of objects that need … See more WebIn mathematics, particularly graph theory, and computer science, a directed acyclic graph (DAG) is a directed graph with no directed cycles.That is, it consists of vertices and edges (also called arcs), with each edge directed from one vertex to another, such that following those directions will never form a closed loop.A directed graph is a DAG if and only if it …
