Spezielle Pathologie des Augenhintergrundes,ed) while the parameter specification is refined contravariantly (i.e., generalized). This refinement is similar to the subtyping relation between function types. Assuming a few relatively weak axioms about parameterized specifications, refinement is shown to satisfy the expected properties for soft

A particularly important aspect for extending existing methods to address composite systems is the ability, given programs that realise component specifications, to synthesise the interconnections between them in such a way that

The linear recursive programs one may derive using this new strategy, have in most cases very good time and space performance. We present our list introduction strategy in the cas

Of equal importance, metaprogramming requires an intuitive foundation that facilitates most frequent, natural manipulations of programs as data. In the past, the program transformation community has characterized well means for expressing pattern-matching and individual

The problem is to compile a subset RCS of Relational Calculus defined by Willard (1978) in a novel way so that efficient run-time query performance is guaranteed.

We will see that this alternative semantics is monotone and implementable (feasible). Finally a programming theorem for iterative constructs is proposed, proved
