Abstract. The conditions under which a formal system for reasoning about structural specifications, built over one logical system could be reused for reasoning about structured spe...
We investigate the rewrite relation over graphs induced by constructor-based weakly orthogonal graph rewriting systems. It is well known that this relation is not confluent in gene...
Abstract. Hidden algebra is a behavioural algebraic specification formalism for objects. It captures their constructional aspect, concerned with the initialisation and evolution of...
Abstract. The ELAN system is an environment for specifying and prototyping constraint solvers, theorem provers and deduction systems in general. It also provides a framework for ex...
