Moderne Stationsorganisation im Krankenhausost . in .. In this paper we consider LexBFS-orderings of chordal, distance-hereditaxy and HHD-free graphs (the graphs where each cycle of length at least five has two chords) with respect to their powers. We show that any LexBFS-ordering of a chordal graph is a common perfect elimination ordering o

Up to now, switchbox routing has been known to be solvable in polynomial time when there are only 2-terminal nets, and to be NP-complete in case there exist nets involving at least five terminals. Our main resul

The main result of this work states that a graph is ..-connected if and only if each pair of vertices is connected by a ..chain. Our proof relies, in part, on a linear-time algorithm

Embedding complete binary trees in product graphs,jn graphs. The main emphasis of the embedding methods presented here is how to emulate arbitrarily large complete binary trees in these product graphs with low slowdown. For the embedding methods presented here the size of the host graph can be fixed to an arbitrary size, while we define no bound on
