We contrast using a notation extension with using a combination of notations. Specifically, we compare the use of an extended dialect of Z [10] with a combination of Z and predicat...
When time is incorporated in the specification of discrete systems, the complexity of verification grows exponentially. When the temporal behavior is specified with symbols, the ve...
Use Cases are a wide-spread informal method for specifying the requirements of a technical system in the early development phase. Z is a formal notation which aims to support, bes...
Sac is a functional array processing language particularly designed with numerical applications in mind. In this field the runtime performance of programs critically depends on the...
We report on the design of a prototyping component for the theorem prover Isabelle/HOL. Specifications consisting of datatypes, recursive functions and inductive definitions are co...
