WebIn mathematics, particularly graph theory, and computer science, a directed acyclic graph (DAG) is a directed graph with no directed cycles. ... Because a DAG cannot have self-loops, its adjacency matrix must have a zero diagonal, so adding I preserves the property that all matrix coefficients are 0 or 1. WebThe graph above has five of them. Now shrink each strongly connected component down to a single meta-node, and draw an edge from one meta-node to another if there is an edge (in the same direction) between their respective components. The resulting meta-graph must be a dag. The reason is simple: a cycle containing several strongly connected ...

WebA topological sort (sometimes also called a linearization) of a directed graph is a list of the vertices in such an order that if there is a directed path from vertex v to vertex w, then v precedes w in the list. (The graph must be acyclic in order for this to work. Directed acyclic graphs are common enough to be referred to by their acronym: DAGs.)
