WebTopologische Sortierung: • Verwende eine FIFO Queue q • Anfangs enthält q alle Knoten, die keine eingehende Kante haben (Quellen). • Verwalte für jeden Knoten Zähler der noch nicht markierten eingehenden Kanten. • Entnehme v aus q und markiere alle (v,w) 2 E, d.h. dekrementiere den Zähler für w. Falls der Zähler von In computer science, a topological sort or topological ordering of a directed graph is a linear ordering of its vertices such that for every directed edge uv from vertex u to vertex v, u comes before v in the ordering. For instance, the vertices of the graph may represent tasks to be performed, and the edges may represent … See more The canonical application of topological sorting is in scheduling a sequence of jobs or tasks based on their dependencies. The jobs are represented by vertices, and there is an edge from x to y if job x must be completed before … See more If a topological sort has the property that all pairs of consecutive vertices in the sorted order are connected by edges, then these edges form a … See more By definition, the solution of a scheduling problem that includes a precedence graph is a valid solution to topological sort (irrespective of the number of machines), however, topological sort in itself is not enough to optimally solve a scheduling optimisation … See more The usual algorithms for topological sorting have running time linear in the number of nodes plus the number of edges, asymptotically, See more The topological ordering can also be used to quickly compute shortest paths through a weighted directed acyclic graph. Let V be the list of vertices in such a graph, in topological order. … See more Topological orderings are also closely related to the concept of a linear extension of a partial order in mathematics. A partially ordered set is just a … See more • tsort, a Unix program for topological sorting • Feedback arc set, a set of edges whose removal allows the remaining subgraph to be topologically sorted • Tarjan's strongly connected components algorithm, an algorithm that gives the topologically sorted … See more
