Optimizing schema-last tuple-store queries in graphd
Current relational databases require that a database schema exist prior to data entry and require manual optimization for best performance. We describe the query optimization tech...

An empirical study of optimizations in YOGI
Though verification tools are finding industrial use, the utility of engineering optimizations that make them scalable and usable is not widely known. Despite the fact that seve...

To be fair or efficient or a bit of both
Introducing a new concept of (, )-fairness, which allows for a bounded fairness compromise, so that a source is allocated a rate neither less than 0 1, nor more than 1, times...

Selectivity-based partitioning: a divide-and-union paradigm for effective query optimization
Modern query optimizers select an efficient join ordering for a physical execution plan based essentially on the average join selectivity factors among the referenced tables. In ...

A comparison study between genetic algorithms and bayesian optimize algorithms by novel indices
Genetic Algorithms (GAs) are a search and optimization technique based on the mechanism of evolution. Recently, another sort of population-based optimization method called Estimat...
