Tight results for Next Fit and Worst Fit with resource augmentation
It is well known that the two simple algorithms for the classic bin packing problem, NF and WF both have an approximation ratio of 2. However, WF seems to be a more reasonable alg...

Extending HCONE-Merge by Approximating the Intended Meaning of Ontology Concepts Iteratively
A central aspect of HCONE-merge is the mapping of ontology concepts to a hidden intermediate ontology by uncovering the intended meaning of concepts. Such a mapping is realized by ...

A Distributed Algorithm for Congestion-Minimized Multi-Path Routing Over Ad-Hoc Networks
When an ad hoc network with limited link capacities is used to transport high-rate, latency-constrained multimedia streams, it is important that routing algorithms not only yield ...

Approximating Maximum Flow in Polygonal Domains using Spanners
We study a maximum flow problem in a polygonal domain P: Determine the maximum number of disjoint "thick" paths (of specified width w) through P from a source edge to a ...
