WebAn introduction to Directed Acyclic Graphs and the algorithm to produce topological orderings of such graphs. The usual algorithms for topological sorting have running time linear in the number of nodes plus the number of edges, asymptotically, One of these algorithms, first described by Kahn (1962), works by choosing vertices in the same order as the eventual topological sort. First, find a list of "start nodes" which have no incoming edges and insert them into a set S; at least one such node must exist in a non-empty acyclic gr…

WebMar 28, 2024 · Topological sort is a technique used in graph theory to order the vertices of a directed acyclic graph (DAG). It ensures that for every directed edge from vertex A to vertex B, vertex A comes before vertex B in the ordering. This is useful in scheduling problems, where tasks depend on the completion of other tasks.
