We contrast our approach with previous work that generates workloads of random spatial ranges, and we sketch directions for future work on the robust generation of workloads for studying in

https://doi.org/10.1007/978-3-031-09334-0ar, most such techniques proposed in the literature are not evaluated versus simple linear scan, and are evaluated over workloads for which nearest neighbor is not meaningful. Often, even the reported experiments, when analyzed carefully, show that linear scan would outperform the techniques being p

Continental Philosophy of Psychiatryre approximation algorithms for several partitioning problems that provably approximate the optimal solutions within small constant factors, and that run in linear or close to linear time. We also establish the NP-hardness of several partitioning problems, therefore it is unlikely that there are eff

Definability and Descriptive Complexity on Databases of Bounded Tree-Widthnt logic. These results have some remarkable consequences concerning the definability of certain classes of graphs..Finally, we show that each database of tree-width at most . can be characterized up to isomorphism in the language C., the (. + 3)-variable fragment of firstorder logic with counting.
