We introduce a generic type system (based on Milner's sort system) for the synchronous polyadic -calculus, allowing us to mechanise the analysis of input/output capabilities o...
In this paper we develop a new elementary algorithm for model-checking infinite sequential processes, including context-free processes, pushdown processes, and regular graphs, tha...
Abstract. We present a generic algorithm for solving Horn clauses through iterative specialisation. The algorithm is generic in the sense that it can be instantiated with any decid...
Early information systems were mainly built around secondary, administrative processes of the value chain (e.g. accounting). But since the internet came into use, more and more pr...
We define fuzzy constraint networks and prove a theorem about their relationship to fuzzy logic. Then we introduce Khayyam, a fuzzy constraint-based programming language in which ...
