Thermodynamik der Verbrennungskraftmaschinef points and an ordered subset . of at least four points, one can always construct a polygon . such that the points of . define the geodesic hull of . w.r.t. ., in the specified order. Moreover, we show that an abstract order type derived from the dual of the Pappus arrangement can be realized as a geodesic order type.

Induced Subgraph Isomorphism: Are Some Patterns Substantially Easier Than Others?, no topology of an induced subgraph of fixed size can be easier to detect or count than an independent set of related size. We show that: .Finally, we show that the so called diamond, paw and .. are not easier to detect as induced subgraphs than an independent set on three vertices.

Restricted Max-Min Fair Allocations with Inclusion-Free Intervals,maximizing the minimum utility received by any agent. When every item can be assigned to any player a PTAS is known [Woe97]. We present a 1/2-approximation algorithm for the addressed more general variant with inclusion-free intervals.

Overthrow

Rainbow Colouring of Split and Threshold Graphs,ned into a clique and an independent set. A . is a split graph in which the neighbourhoods of the independent set vertices form a linear order under set inclusion. In this article, we show the following:
