The goal of this study is to introduce and observe analysis by reduction of dependency trees. We focus on formalization of certain minimalistic properties of analysis by reduction of dependency trees, and its complexity issues.

Syntax-based machine translation (MT) is an attractive approach for introducing additional linguistic knowledge in corpus-based MT. Previous studies have shown that treeto-string and string-to-tree translation models perform better than tree-to-tree translation models since tree-to-tree models require two high quality parsers on the source as well as the target language side. In practice, high ...

Restricted rotation distance between pairs of rooted binary trees quantifies differences in tree shape. Cleary exhibited a linear upper bound of 12n for the restricted rotation distance between two trees with n interior nodes, and a lower bound of (n − 1)/3 if the two trees satisfy a reduction condition. We obtain a significantly improved sharp upper bound of 4n− 8 for restricted rotation dista...

As network traffic throughput requirements continue to increase dramatically, network processors are adding specialized instructions that accelerate the more common arithmetic operations. An example is the checksum, which appears in several popular protocols to guard against using corrupted packets. This paper presents two approaches to checksum calculation that provide significant performance ...

Trees can be conveniently compressed with linear straight-line contextfree tree grammars. Such grammars generalize straight-line context-free string grammars which are widely used in the development of algorithms that execute directly on compressed structures (without prior decompression). It is shown that every linear straight-line context-free tree grammar can be transformed in polynomial tim...

We present a structure for transition systems with which the main decidability results on Petri nets can be generalized to structured transition systems. We define the reduced reachability tree of a structured transition system; it allows one to decide the finite reachability tree problem (also called the finite termination problem) and the finite reachability set problem. A general definition ...

Theoretical models predict that animals should make foraging decisions after assessing the quality of available habitat, but most models fail to consider the spatio-temporal scales at which animals perceive habitat availability. We tested three foraging strategies that explain how Magellanic woodpeckers (Campephilus magellanicus) assess the relative quality of trees: 1) Woodpeckers with local k...
