Although many formalisms have been proposed for reasoning about intelligent agents, few of these have been semantically grounded in a concrete computational model. This paper prese...
Narrowing extends rewriting with logic capabilities by allowing free variables in terms and replacing matching with unification. Narrowing has been widely used in different context...
We logically model uncertainty by expanding language without changing logical reasoning rules. We expand the language of set theory by adding new predicate symbols, uncertain membe...
Partial functions and operators are used extensively in the formal development of programs and thus development methods have to clarify how to reason about them. There are a numbe...
This paper introduces a logical system, called BV , which extends multiplicative linear logic by a non-commutative self-dual logical operator. This extension is particularly challe...
