Lawful functions and program verification in Miranda

Lawful Functions and Program Verification in Miranda

Laws in the Miranda programming language provide a means of implementing non-free algebraic types, by means of term rewriting. In this paper we investigate program veri cation in such a context. Speci cally, we look at how to deduce properties of functions over these `lawful' types. After examining the general problem, we look at a particular class of functions, the faithful functions. For such...

a contrastive study of rhetorical functions of citation in iranian and international elt scopus journals

writing an academic article requires the researchers to provide support for their works by learning how to cite the works of others. various studies regarding the analysis of citation in m.a theses have been done, while little work has been done on comparison of citations among elt scopus journal articles, and so the dearth of research in this area demands for further investigation into citatio...

Program verification in Smalltalk

Fresco is a Smalltalk-based interactive environment supporting the specification and proven development of re-usable software components. These ‘capsules’ are deltas to the inheritance hierarchy, and form a more useful unit of designer-effort than class subhierarchies. Systems are built by composing capsules, which carry both specifications and code. The semantics of capsule composition is eluc...

Program Verification

Program Transformation for Program Verification

We present a transformational approach to program verification and software model checking that uses three main ingredients: (i) Constraint Logic Programming (CLP), (ii) metaprogramming and program specialization, and (iii) proof by transformation. (i) Constraints are used for representing in a compact way (finite or infinite) sets of values or memory states, and logic is used for expressing pr...
