NNrepair: Constraint-Based Repair of Neural Network Classifiers
We present NNrepair, a constraint-based technique for repairing neural network classifiers. The technique aims to fix the logic of the network at an intermediate layer or at the last layer. NNrepair first uses fa...

Building Better Bit-Blasting for Floating-Point Problems
An effective approach to handling the theory of floating-point is to reduce it to the theory of bit-vectors. Implementing the required encodings is complex, error prone and requires a deep understanding of flo...

Reachability Preservation Based Parameter Synthesis for Timed Automata
The synthesis of timing parameters consists in deriving conditions on the timing constants of a concurrent system such that it meets its specification. Parametric timed automata are a powerful formalism for pa...

Parametric Schedulability Analysis of Fixed Priority Real-Time Distributed Systems
In this paper, we address the problem of parametric schedulability analysis of distributed real-time systems scheduled by fixed priority. We propose two different approaches to parametric analysis. The first o...
