Worst-case optimal join algorithms: Techniques, results, and open problems
HQ Ngo - Proceedings of the 37th ACM SIGMOD-SIGACT-SIGAI …, 2018 - dl.acm.org
Worst-case optimal join algorithms are the class of join algorithms whose runtime match the
worst-case output size of a given join query. While the first provably worse-case optimal join …

On the expressive power of linear algebra on graphs
F Geerts - Theory of Computing Systems, 2021 - Springer
There is a long tradition in understanding graphs by investigating their adjacency matrices
by means of linear algebra. Similarly, logic-based graph query languages are commonly …

On the expressive power of query languages for matrices
We investigate the expressive power of MATLANG, a formal language for matrix
manipulation based on common matrix operations and linear algebra. The language can be …

Coresets for relational data and the applications
A coreset is a small set that can approximately preserve the structure of the original input
data set. Therefore we can run our algorithm on a coreset so as to reduce the total …

Graphical Join: A New Physical Join Algorithm for RDBMSs
Join operations (especially n-way, many-to-many joins) are known to be time-and resource-
consuming. At large scales, with respect to table and join-result sizes, current state of the art …
