 +====== Language ======
 +
 +
 +The default language is French.\\
 +But the lectures may be given in English if attended by non French-speaking students.
 +
 +====== Motivations and main objectives ======
 +
 +
 +Nowadays, it is of the highest importance to use formal methods in order to increase the reliability of critical systems.
 +\\
 +In this introductory course on verification of discrete systems, we concentrate in particular on //model checking// techniques.
 +\\
 +We will describe various models used to define systems: transition systems enriched with various data structures (variables, channels, ...) and which can be composed with several synchronization mechanisms.
 +\\
 +We will also cover specification languages that are used to express properties to be checked on our systems: temporal logics (linear or branching), first-order or monadic second-order logic, ...
 +\\
 +We will study expressivity, decidability and complexity properties of our models and specification languages.
 +\\
 +We will also cover abstraction/refinement techniques and (bi)simulation relations used to relate various abstraction levels.
 +\\
 +Algorithmic aspects of model checking will be investigated and we will stress efficient techniques such as binary decision diagrams (BDDs) or bounded model checking.
 +/*
 +Pour cela nous introduirons divers modèles d'automates sur les mots infinis (Büchi, Muller, parité, ...) et aussi alternants.
