Fixed-Parameter Algorithms for DAG Partitioning
René van Bevern, Robert Bredereck, Morgan Chopin +4
Finding the origin of short phrases propagating through the web has been formalized by Leskovec et al. [ACM SIGKDD 2009] as DAG Partitioning: given an arc-weighted directed acyclic…
Constant-factor approximations for Capacitated Arc Routing without triangle inequality
René van Bevern, Sepp Hartung, André Nichterlein +1
Given an undirected graph with edge costs and edge demands, the Capacitated Arc Routing problem (CARP) asks for minimum-cost routes for equal-capacity vehicles so as to satisfy all…
Parameterized Inapproximability of Target Set Selection and Generalizations
Cristina Bazgan, Morgan Chopin, André Nichterlein +1
In this paper, we consider the Target Set Selection problem: given a graph and a threshold value for any vertex of the graph, find a minimum size vertex-subset to "act…
