NSV 22

15th International Workshop on Numerical Software Verification 2022
collocated with FLoC, August 11, 2022
Haifa, Israel



Numerical computations are ubiquitous in digital systems: supervision, prediction, simulation and signal processing rely heavily on numerical calculus to achieve desired goals. Design and verification of numerical algorithms has a unique set of challenges, which set it apart from rest of software verification. To achieve the verification and validation of global properties, numerical techniques need to precisely represent local behaviors of each component. The implementation of numerical techniques on modern hardware adds another layer of approximation because of the use of finite representations of infinite precision numbers that usually lack basic arithmetic properties such as commutativity and associativity. Finally, the development and analysis of cyber-physical systems (CPS) which involve the interaction of continuous and discrete components poses a further challenge. It is hence essential to develop logical and mathematical techniques for reasoning about programmability and reliability. The NSV workshop is dedicated to the development of such techniques.


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

  • Quality of finite precision numerics
    • Representations of real numbers such as dfloat, finite precision, logarithmic number systems, etc
  • Validation and verification of machine learning algorithms
    • Performance-accuracy trade-offs in floating point representations in machine learning
    • Robustness, reliability, and hardware software co-design for numerical computations in machine learning
  • Validation and verification in scientific computing and simulations
    • Specifications of correctness of numerical algorithms
    • Numerical optimization methods
  • Hybrid systems and control software verification
    • Quantitative and qualitative analysis of hybrid systems
    • Optimal control and synthesis of dynamical systems
    • Applications in space, avionics, automotive, systems biology, etc

Instructions for Authors

We solicit regular and short papers. Paper submission must be performed via the EasyChair system: https://easychair.org/conferences/?conf=nsv2022.

Regular papers must describe original work, be written and presented in English, and must not substantially overlap with papers that have been published or that are under submission. Submitted papers will be judged on the basis of significance, relevance, correctness, originality, and clarity. They should clearly identify what has been accomplished and why it is significant.

Regular paper submissions should not exceed 15 pages in LNCS style, plus possibly bibliography and appendices. However, program committee members are not required to read the appendices, thus papers must be intelligible without them.

Short papers are also welcome: they should present tools, benchmarks, case-studies or be extended abstracts of ongoing research. Short papers should not exceed 6 pages, excluding extra material as above.

All accepted papers will be published as Lecture Notes in Computer Science (LNCS) with Springer.
