Economic modelling using constraint logic programming [PDF]

open access: yes, 1996
This paper investigates the use of constraint logic programming (CLP) in economic modelling through the design and implementation of two economic models.

Program transformation for development, verification, and synthesis of programs [PDF]

open access: yes, 2011
This paper briefly describes the use of the program transformation methodology for the development of correct and efficient programs. In particular, we will refer to the case of constraint logic programs and, through some examples, we will show how by ...

Sets and constraint logic programming

open access: yesACM Transactions on Programming Languages and Systems, 2000
In this paper we present a study of the problem of handling constraints made by conjunctions of positive and negative literals based on the predicate symbols =, ∈,∪ and || (i.e., disjointness of two sets) in a (hybrid) universe of finite sets .

On termination of constraint logic programs [PDF]

open access: yes, 1995
This paper introduces a necessary and sufficient condition for termination of constraint logic programs. The method is based on assigning a dataflow graph to a program, whose nodes are the program points and whose arcs are abstractions of the rules of a transition system, describing the operational behaviour of constraint logic programs.

Constraint Logic Programming: A Survey

open access: yesThe Journal of Logic Programming, 1994
Constraint Logic Programming (CLP) began as a natural merger of two declarative paradigms: constraint solving and logic programming. This combination helps make CLP programs both expressive and flexible, and in some cases, more efficient than other kinds of programs.

Typing constraint logic programs [PDF]

open access: yesTheory and Practice of Logic Programming, 2001
We present a prescriptive type system with parametric polymorphism and subtyping for constraint logic programs. The aim of this type system is to detect programming errors statically. It introduces a type discipline for constraint logic programs and modules, while maintaining the capabilities of performing the usual coercions between constraint ...

Unfounded Sets and Well-Founded Semantics of Answer Set Programs with Aggregates [PDF]

open access: yes, 2011
Logic programs with aggregates (LPA) are one of the major linguistic extensions to Logic Programming (LP). In this work, we propose a generalization of the notions of unfounded set and well-founded semantics for programs with monotone and antimonotone ...

Independence in CLP Languages [PDF]

open access: yes, 2000
Studying independence of goals has proven very useful in the context of logic programming. In particular, it has provided a formal basis for powerful automatic parallelization tools, since independence ensures that two goals may be evaluated in parallel ...

Induction of constraint logic programs [PDF]

open access: yes, 1998
Inductive Logic Programming (ILP) is concerned with learning hypotheses from examples, where both examples and hypotheses are represented in the Logic Programming (LP) language. The application of ILP to problems involving numerical information has shown the need for basic numerical background knowledge (e.g. relation “less than”).
