Susanne Milleror (1) we propose grid embeddings of graphs and measure ”nice” by algorithmic cost measures of the embeddings, e.g., area, expansion, edge length, etc. For (2) we prove that optimal embeddings with fixed costs are NP-complete, even for binary trees. This sharpens previous NP-completeness results of

Marius Harringsor networks as they can be used to model link scheduling problems in such networks. It is well known that both problems are NP-complete, and approximation algorithms for them have been extensively studied under the centralized model of computation. Centralized algorithms, however, are not suitable

Falk Radisch,Ludwig Stecher,Natalie Fisch,Eckhard Kliememe flow, i.e., they are gainy or lossy. The objective is a cheapest path of a unit flow from the source (SGSP) and the single-pair cheapest path (SPGSP)..There are several types of negative cycles. A lossy cycles decreases the gain. Then even a negative cost cycle has only bounded cost. A gainy cycl

Carsten Rohlfsunded clique-width. It is known that many hard graph problems have polynomial-time algorithms for graphs of bounded clique-width, however, requiring a given decomposition corresponding to clique-width (.); they remove this requirement by constructing an algorithm that either outputs a rank-decomposi
