Georg Müller-Christ,Michael Hülsmanntiplication are recognition of transitive graphs, computing the transitive closure of a directed acyclic graph, and finding the neighborhood containment matrix of a graph. In this paper, we show how to avoid using matrix multiplication for these problems on special classes of graphs. This leads to e

Modernisierung oder Überfremdung?igraph (DAG). The main results in this paper are (n=|V|) :.(1) An O(n* log(n)) approximation algorithm is developed for the minimum-fas-problem on planar digraphs with a worst-case-ratio of 2. In the case of a planar digraph with all embeddings in the plane having at most one clockwise/anticlockwise

https://doi.org/10.1007/978-3-642-59152-5 consists of a set of . interconnecting the terminals belonging to the same (multi-terminal) net. An algorithm, unifying and generalizing previous BSLR algorithms, to solve an arbitrary instance of BSLR, is presented. Problems involving slidable terminals (i.e., when terminals can slide within a cer

As the Steiner Problem is NP-hard, GSP is too, and we are interested in approximation algorithms. Efficient approximation algorithms have already been proposed, but noth
