282 results about "Directed acyclic graph" patented technology

In mathematics, particularly graph theory, and computer science, a directed acyclic graph (DAG /ˈdæɡ/ ) is a finite directed graph with no directed cycles. That is, it consists of finitely many vertices and edges (also called arcs), with each edge directed from one vertex to another, such that there is no way to start at any vertex v and follow a consistently-directed sequence of edges that eventually loops back to v again. Equivalently, a DAG is a directed graph that has a topological ordering, a sequence of the vertices such that every edge is directed from earlier to later in the sequence.
