Recognizing HHD-free and Welsh-Powell Opposition Graphsgraphs (or WPO-graphs). In particular, we prove properties of the chordal completion of a graph and show that a modified version of the classic linear-time algorithm for testing for a perfect elimination ordering can be efficiently used to determine in .( min {...(.), . + .. log .}) time whether a g

Decremental Clique Problemthe decremental version of clique problem, where the property of containing an ?-clique is dynamically checked during deletions of nodes. We provide an improved dynamic algorithm for this problem for every fixed value of ? ≥ 3. Our algorithm naturally applies to filtering for the constraint satisfac

A Graph-Theoretic Generalization of the Least Common Subsumer and the Most Specific Concept in the Diption logic . in the presence of terminological cycles that are interpreted with descriptive semantics, which is the usual first-order semantics for description logics. In this setting, neither the lcs nor the msc needs to exist. We were able to characterize the cases in which the lcs/msc exists, b

A Robust PTAS for Maximum Weight Independent Sets in Unit Disk Graphsight independent set problem in unit disk graphs. In contrast to previously known approximation schemes, our approach does not require a geometric representation (specifying the coordinates of the disk centers)..The approximation algorithm presented is robust in the sense that it accepts any graph a

Tolerance Based Algorithms for the ATSPATSP). We derive new tighter lower bounds based on exact and approximate bottleneck upper tolerance values of the Assignment Problem (AP). It is shown that branching by tolerances provides a more rational branching process than branching by costs. Among others, we show that branching on an arc with
