Internal consistency for embedding complexity
In a previous paper with M. Dzamonja, class forcings were given which fixed the complexity (a universality covering number) for certain types of structures of size together with ...

A 2-approximation for the preceding-and-crossing structured 2-interval pattern problem
The 2-interval pattern problem over its various models and restrictions was proposed by Vialette (2004) for the application of RNA secondary structure prediction. We present an O(n...

The A-tree: An Index Structure for High-Dimensional Spaces Using Relative Approximation
We propose a novel index structure, A-tree (Approximation tree), for similarity search of high-dimensional data. The basic idea of the

Approximation algorithms for restricted Bayesian network structures
Bayesian Network structures with a maximum in-degree of k can be approximated with respect to a positive scoring metric up to an factor of 1/k. Key words: approximation algorithm,...
