Algebraic Multigrid Solvers for Complex-Valued Matrices
In the mathematical modeling of real-life applications, systems of equations with complex coefficients often arise. While many techniques of numerical linear algebra, e.g., Krylovs...

Efficiently Certifying Non-Integer Powers
We describe a randomized algorithm that, given an integer a, produces a certificate that the integer is not a pure power of an integer in expected (log a)1+o(1) bit operations unde...

A state-based framework for supervisory control synthesis and verification
We extend an existing model-based framework for supervisory control synthesis with generalized control and verification state-based requirements. The former stem from the need for ...

Model Checking for Verification of Mandatory Access Control Models and Properties
rather wide gap in abstraction between policies and mechanisms. In this paper, we propose a general approach for property verification for MAC models. The approach defines a stan...

Computational reproducibility: state-of-the-art, challenges, and database research opportunities
Computational experiments have become an integral part of the scientific method, but reproducing, archiving, and querying them is still a challenge. The first barrier to a wider...
