An O(n2.75) Algorithm for Online Topological Ordering
نویسندگان
چکیده
We present a simple algorithm which maintains the topological order of a directed acyclic graph with n nodes under an online edge insertion sequence in O(n) time, independent of the number of edges m inserted. For dense DAGs, this is an improvement over the previous best result of O(min{m 2 log n,m 3 2 + n log n}) by Katriel and Bodlaender. We also provide an empirical comparison of our algorithm with other algorithms for online topological sorting.

Faster Algorithms for Online Topological Ordering
We present two algorithms for maintaining the topological order of a directed acyclic graph with n vertices, under an online edge insertion sequence of m edges. Efficient algorithms for online topological ordering have many applications, including online cycle detection, which is to discover the first edge that introduces a cycle under an arbitrary sequence of edge insertions in a directed grap...

متن کاملeb 2 00 8 Average - Case Analysis of Online Topological Ordering ∗
Many applications like pointer analysis and incremental compilation require maintaining a topological ordering of the nodes of a directed acyclic graph (DAG) under dynamic updates. All known algorithms for this problem are either only analyzed for worst-case insertion sequences or only evaluated experimentally on random DAGs. We present the first average-case analysis of online topological orde...
متن کاملThe topological ordering of covering nodes
The topological ordering algorithm sorts nodes of a directed graph such that the order of the tail of each arc is lower than the order of its head. In this paper, we introduce the notion of covering between nodes of a directed graph. Then, we apply the topological orderingalgorithm on graphs containing the covering nodes. We show that there exists a cut set withforward arcs in these...
