New Integrality Gap Results for the Firefighters Problem on Trees,tions for the firefighter problem. We first show a matching lower bound of . on the integrality gap of the canonical LP. This result relies on a powerful . that can be used to derive integrality gap results in other related settings. Next, we consider the canonical LP augmented with simple additiona

Gewebsmastzellen und Mastzellen-Reticulose,f the online and offline models. We provide several results, including a general result for sum coloring and results for the classic graph coloring problem on restricted graph classes: We show tight bounds for any graph class containing trees as a subclass (e.g., forests, bipartite graphs, planar gr

Dynamic Traveling Repair Problem with an Arbitrary Time Window,or service at nodes in a metric space and a time window for each request. The goal is to maximize the number of requests served during their time window. The time to traverse between two points is equal to the distance. Serving a request requires unit time. Irani et al., SODA 2002 considered the spe

A PTAS for the Cluster Editing Problem on Planar Graphs,of disjoint cliques. The cluster editing problem is closely related to correlation clustering and has applications, e.g. in image segmentation. For general graphs this problem is .-hard. In this paper we present an efficient polynomial time approximation scheme for the cluster editing problem on gra
