model checking

You are here: irt.org | FOLDOC | model checking

<theory, algorithm, testing> To algorithmically check whether a program (the model) satisfies a specification.

The model is usually expressed as a directed graph consisting of nodes (or vertices) and edges. A set of atomic propositions is associated with each node. The nodes represents states of a program, the edges represent possible executions which alters the state, while the atomic propositions represent the basic properties that hold at a point of execution.

A specification language, usually some kind of temporal logic, is used to express properties.

The problem can be expressed mathematically as: given a temporal logic formula p and a model M with initial state s, decide if M,s \models p.
