Deductive Verification Sample Clauses

Deductive Verification. ⊢ In deductive verification, the system intended to be proved correct is described by a set of formulas called axioms and the correctness property is expressed by a formula in the same language of axioms. The process of verification is to derive a proof of the desired correctness property based on the set of axioms. In other words, if the property to be verified, say ϕ, is expressed in a formal language with a well-established proof theory, and the system is specified by a set of formulas Γ, the deductive verification method is to try to find a proof for Γ ϕ. Obviously, if we are interested to do the deductive verification automatically, we need to have an implemented automatic theorem prover for the formal language in which the axioms and the desired property are expressed. Typically, it is supposed that an expert (mathematician or logician) uses the theorem prover and helps it to find the best ways of doing the proof. The facts that only experts can use a theorem prover and fully automated theorem provers are not found are of the main disadvantages of the method of deductive verification. Another problem with theorem proving is that it is not particulary suitable in providing debugging information, that is, information on the nature and location of errors [139]. An advantage of deductive verification is that it can be used for reasoning about infinite state systems such as systems that work on unbounded data types (for instance the ordinary integers). As another example, theorem proving techniques work well when process struc- tures evolve, that is, new processes can be added and old processes can be aborted during the executions of the system [139]. In these cases, the task of deductive verification can be automated to a limited extent. However, even if the property to be verified is true, no limit can be placed on the amount of time or memory that may be needed in order to find a proof [50].
