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.
