Abstract
Formal methods advocate the crucial role played by the algebraic approach in specification and implementation of programs. Traditionally, a top-down approach (with denotational model as its origin) links the algebra of programs with the denotational representation by establishment of the soundness and completeness of the algebra against the given model, while a bottom-up approach (a journey started from operational model) introduces a variety of bisimulations to establish the equivalence relation among programs, and then presents a set of algebraic laws in support of program analysis and verification. This paper proposes a new roadmap for linking theories of programming. Our approach takes an algebra of programs as its foundation, and generates both denotational and operational representations from the algebraic refinement relation. This new approach is applied in this paper to GCL (Guarded Command Language) and CSP (Communicating Sequential Processes) to link their various semantical representations based on their algebraic semantics. • A new roadmap for linking theories of programming from program algebra. • This paper demonstrates the approach to GCL and CSP. • Varies denotational models can be derived from the program algebra. • Consistent operational semantics can be derived from the program algebra.
