Short Labels for Lowest Common Ancestors in Trees
We evaluate the practical performance of labeling schemes for lowest common ancestors in trees. We develop different variants for encoding the labels. We then perform a thorough e...

Computing and Exploiting Tree-Decompositions for Solving Constraint Networks
Methods exploiting tree-decompositions seem to provide the best approach for solving constraint networks w.r.t. the theoretical time complexity. However, they have not shown a real...

Heuristic Methods for Solving Euclidean Non-uniform Steiner Tree Problems
In this paper, we consider a variation of the Euclidean Steiner Tree Problem in which the space underlying the set of nodes has a specified non-uniform cost structure. This proble...

The repeater tree construction problem
A tree-like substructure on a computer chip whose task it is to carry a signal from a source circuit to possibly many sink circuits and which consists only of wires and so-called ...

Efficient Transformation-Based Parsing
In transformation-based parsing, a finite sequence of tree rewriting rules are checked for application to an input structure. Since in practice only a small percentage of rules ar...
