We revisit the problem of real-time verification with dense-time dynamics using timeout and calendar-based models and simplify this to a finite state verification problem. We introduce a specification formalism for these models and capture their ...

In the context of testing from algebraic specifications, test cases are ground formulas chosen amongst the ground semantic consequences of the specification, according to some possible additional observability conditions. A test set is said to be ...

In this paper, we formalize the defect-prediction problem as a multiobjective optimization problem. Specifically, we propose an approach, coined as multiobjective defect predictor MODEP, based on multiobjective forms of machine learning techniques-...

This article presents a novel cost analysis framework for concurrent objects. Concurrent objects form a well-established model for distributed concurrent systems. In this model, objects are the concurrency units that communicate among them via ...

We propose a theoretical testing framework and a test generation algorithm for concurrent systems specified with true-concurrency models, such as Petri nets or networks of automata. The semantic model of computation of such formalisms is labelled event ...

Several proof formats have been used to verify refutations produced by satisfiability SAT solvers. Existing formats are either costly to check or hard to implement. This paper presents a practical approach that facilitates checking of unsatisfiability ...

Developing efficient and automatic testing techniques is one of the major challenges faced by the software validation community. Recent work by A. Denise et al. shows how to draw traces uniformly at random for testing large systems modelled by finite ...
