Model checking, introduced 20 years ago, combines several fully automatic techniques in which the property to be checked is tested exhaustively on all the possible executions of the system. It is an automated approach to verifying that a system meets its specifications. The main limit to the use of model checking is related to the state explosion p...

Model checking is a very powerful formal verification technique. Formal verification of complex systems is a major challenge in many areas of human society. The verification of properties of these systems is recognized as a difficult problem and faces a number of practical and theoretical problems. The main limitation of the formal verification is...

Model checking has long been used as a means of verification of formal specifications. This is a verification technique of dynamic systems that explores all possible states of the system. It determines whether the given system satisfies its specification. This technique suffers from the state explosion problem when traversing all possible states of...

In this article, we are interested in the exploration part of model checking which consists in traversing all the possible states of a system. We propose two approaches to exploration, parallel and sequential. We present a comparison between our parallel approach and the parallel algorithm proposed in SPIN.

In the life cycle of any software system, a crucial phase formalization and validation through verification or testing induces an identification of errors infiltrated during its design. This is achieved through verification by model checking. A model checking algorithm is based on two steps: the construction of state space of the system specificati...
