Effective and Efficient Lexicographical Order Dependency Discovery

IEEE Transactions on Knowledge and Data Engineering, 2023
Lexicographical order dependencies state relationships of order between lists of attributes. They naturally model the order-by clauses in SQL queries, and are proven useful in query optimizations concerning sorting.

Quasi-stability and quasi-synchronization control of quaternion-valued fractional-order discrete-time memristive neural networks

Applied Mathematics and Computation, 2021
A discrete-time fractional-order quaternion-valued memristive system is considered in this note. By utilizing contraction mapping theory, a sufficient condition for the existence and uniqueness of the equilibrium point for the considered system is ...

Approximate Order Dependency Discovery

IEEE International Conference on Data Engineering, 2021

Soft Constraints for Lexicographic Orders

2013
While classical Constraint Satisfaction Problems (CSPs) concern the search for the boolean assignment of a set of variables that has to satisfy some given requirements, their soft variant considers ordered domains for assignments, thus modeling preferences: the aim is to provide an environment where suitable algorithms (e.g.
