Visible to the public NSV 2014

7th International Workshop on Numerical Software Verification

July 17-18, 2014

A Satellite Workshop of Vienna Summer of Logic 2014, Collocated with CAV 2014

Novelty of this edition
The 2014 edition of NSV will be published electronically by Elsevier in the Electronic Notes in Theoretical Computer Science Serie (ENTCS).

In this new NSV edition, we encourage publications about the numerical issues in new domains, in particular computational finance and biological systems: problems, consequences and state-of-the-art approaches.

Description of the Workshop
Numerical computations are ubiquitous in digital systems: supervision, prediction, simulation and signal processing rely heavily on numerical calculus to achieve desired goals. Verification of numerical algorithms has a unique set of challenges, which set it apart from the rest of software verification. To achieve the verification and
validation of global properties, numerical techniques need to precisely represent local behaviors of each component. In fact, in numerical algorithms, coarse abstractions are unlikely to succeed essentially because of the above mentioned issue. The implementation of numerical techniques on modern hardware adds another layer of
approximation: the use of finite representations of infinite precision numbers usually lack basic arithmetic properties such as commutativity and associativity. It is hence imperative to develop logical and mathematical techniques that would allow reasoning about programmability and reliability. The NSV workshop is dedicated to the
current development and the future prospects for such techniques.

The scope of the workshop includes, but is not restricted to, the
following topics:

  • Models and abstraction techniques
  • Specifications of correctness for numerical programs
  • Formal specification and verification of numerical programs
  • Quality of finite precision implementations
  • Propagation of uncertainties, deterministic and probabilistic models
  • Numerical properties of control software
  • Hybrid systems verification
  • Validation for space, avionics, automotive and real-time applications
  • Validation for scientific computing programs
  • Optimality of program behavior
  • Trade-offs between quality of service and resource (for example energy) consumption in programs
  • Benchmarks and tools for numerical software verification
  • Numerical issues in computational finance
