Formal methods in software engineering

Formal method in software engineering, software specification is a description of software system object, object operation method, and object behavior. During the development and evolution of the system, the object, the nature of the object and the operation should be treated as a whole. Formal proof and experimental techniques include model detection and theorem proving. The program refinement is the combination of automatic inference and formal method, and the whole process of the concrete computer-oriented program code is pushed from the abstract formal specification. Modal logic describes and calculates propositions in a possible world by introducing "possible" and "inevitable" two modal words. The tagging algorithm is a simple algorithm for model verification.
