This paper presents a method for representing trees using constraint logic programming over finite domains. We describe a class of trees that is of particular interest to us and h...
Abstract. Subtyping tends to undermine the effects of parametric polymorphism as far as the static detection of type errors is concerned. Starting with this observation we present...
If one has attributed certain initial beliefs to an agent, it is sometimes possible to reason about further beliefs the agent must hold by observing what conclusions one's ow...
In this paper we study the interaction of subtyping and parametricity. We describe a logic for a programming language with parametric polymorphism and subtyping. The logic support...
