Hidden algebra provides a formal semantics for use in the field of software engineering, especially for concurrent distributed object systems.[1] It supports correctness proofs.[2]
Hidden algebra was studied by Joseph Goguen.[3] It handles features of large software-based systems, including concurrency, distribution, nondeterminism, and local states. It also handled object-oriented features like classes, subclasses (inheritance), attributes, and methods. Hidden algebra generalizes process algebra and transition system approaches.
