Abstract. We extend the refinement calculus to permit the derivation of programs in the Bulk Synchronous Parallelism (BSP) style. This demonstrates that formal approaches developed...
This paper proposes a new calculus for expressing the behaviour of object-oriented systems. The semantics of the calculus is given in terms of operators from computational categor...
Abstract. Church's Problem (1962) asks for the construction of a procedure which, given a logical specification on sequence pairs, realizes for any input sequence X an output...
Abstract. Refinement concepts, such as procedural and data refinement, are among the most important ideas of software engineering. In this paper, we investigate the idea of design ...
