A numerical algorithm for zero counting, I: Complexity and accuracy
We describe an algorithm to count the number of distinct real zeros of a polynomial (square) system f. The algorithm performs O(log(nD(f))) iterations (grid refinements) where n is...

A Constant Average Time Algorithm to Allow Insertions in the LAESA Fast Nearest Neighbour Search Index
Abstract—Nearest Neighbour search is a widely used technique in Pattern Recognition. In order to speed up the search many indexing techniques have been proposed. However, most of...

End-to-end Fairness Analysis of Fair Queuing Networks
In this paper, we present the first end-to-end fairness analysis of a network of fair servers. We argue that it is difficult to extend existing single-node fairness analysis to ...

Distribution-Aware Compressed Full-Text Indexes
Abstract. In this paper we address the problem of building a compressed self-index that, given a distribution for the pattern queries and a bound on the space occupancy, minimizes ...

The Isomorphism Problem for k-Trees Is Complete for Logspace
Abstract. We show that k-tree isomorphism can be decided in logarithmic space by giving a logspace canonical labeling algorithm. This improves over the previous StUL upper bound an...
