Prioritizing Default Logic,lem which has been studied intensively in the context of inheritance networks (Poole, 1985; Touretzky, 1986; Touretzky et al., 1991). When defaults are used for representing design goals in configuration tasks conflicts naturally arise. The same is true in model based diagnosis where defaults are us

A Connection Calculus for Handling Incomplete Information, is a great need for systematic methods that allow us to integrate default reasoning capabilities. In fact, the two last decades have provided us with a profound understanding of the underlying problems and have resulted in well-understood formal approaches to default reasoning. Therefore, we are no

The Connection Method, Constraints and Model Building,m is to capture the standard attitude of a human being faced to a conjecture: trying . to . or to . it. It is indeed very likely that search for a counter-example of a given formula often helps to find a proof, and conversely: informations deduced during proof search often guide the search for a cou

For instance, an aircraft may be traced by a radar, and at a given time, for some technical reasons, the aircraft is no more in the scope of the radar. Another example may be found in a database which is used for personnel management in a company. When an employee leaves the company we

The Cut Rule in Theorem Proving,hod (Bibel, 1987) — the idea of taking a cut-free affirmative proof calculus and of applying its rules in a backward direction, with redundancies and irrelevant information removed in order to allow efficient automation. In the case of an input sentence in disjunctive normal form, this implies that

Matrix-Based Constructive Theorem Proving,ions. Because of that there is no single automated proof procedure that can handle all the reasoning problems occurring during a program derivation or verification. Instead, one usually relies on proof assistants like NuPRL (Constable et al., 1986), Coq (Dowek and et. al, 1991), Alf (Altenkirch et a
