We define three composition and structuring concepts which reflect frequently used refinements of ASMs and integrate standard structuring constructs into the global state based ...
Abstract. This paper introduces the concepts of wide classes and widening as extensions to the object model of class-based languages such as Java and Smalltalk. Widening allows an ...
Formal verification methods are used only sparingly in software development. The most successful methods to date are based on the use of model checking tools. To use such he user ...
We present a computation-centric theory of memory models. Unlike traditional processor-centric models, computation-centric models focus on the logical dependencies among instructi...
Query optimizers normally compile queries into one optimal plan by assuming complete knowledge of all cost parameters such asselectivity and resourceavailability. The execution of...
