Model checking
Model checking is a software technology consisting in
algorithmically checking whether a model (often deriving from a
hardware or
software design) satisfies a
logical 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 :.
