Integrating answer set programming and constraint logic programming

Veena S. Mellarkod, Michael Gelfond, Yuanlin Zhang
2008 Annals of Mathematics and Artificial Intelligence  
The algorithm does not require full grounding of a program and combines "classical" ASP solving methods with constraint logic programming techniques and CR-Prolog based abduction.  ...  We belief that further investigation of the language and development of more efficient and reliable solvers for its programs can help to substantially expand the domain of applicability of the answer set  ...  Acknowledgments This work was supported in part by NASA contract NASA-NEG05GP48G and ATEE/DTO contract ASU-06-C-0143.  ...

Adding partial functions to Constraint Logic Programming with sets

2015 Theory and Practice of Logic Programming  
In this paper we propose to add partial functions as a primitive feature to a Constraint Logic Programming (CLP) language, namely {log}.  ...  Although partial functions could be programmed on top of {log}, providing them as first-class citizens adds valuable flexibility and generality to the form of set-theoretic formulas that the language can  ...  {log} {log} is a Constraint Logic Programming (CLP) language, whose constraint domain is that of hereditarily finite sets-i.e., finitely nested sets that are finite at each level of nesting.  ...

Learning weak constraints in answer set programming

2015 Theory and Practice of Logic Programming  
AbstractThis paper contributes to the area of inductive logic programming by presenting a new learning framework that allows the learning of weak constraints in Answer Set Programming (ASP).  ...  The framework, calledLearning from Ordered Answer Sets, generalises our previous work on learning ASP programs without weak constraints, by considering a new notion of examples asorderedpairs of partial  ...  A program P is assumed to be a finite set of normal rules, choice rules, and constraints.  ...

ASP (): Answer Set Programming with Algebraic Constraints

2020 Theory and Practice of Logic Programming  
Using a novel combination of Weighted Logic and Here-and-There (HT) Logic, in which this dependence is based on intuitionistic grounds, we introduce Answer Set Programming with Algebraic Constraints (ASP  ...  Such constraints provide streamlined access to a manifold of constructs available in ASP, like aggregates, choice constraints, and arithmetic operators.  ...  This work has been supported by FWF project W1255-N23 and by FFG project 861263.  ...

Tractable answer-set programming with weight constraints: bounded treewidth is not enough

2012 Theory and Practice of Logic Programming  
AbstractCardinality constraints or, more generally, weight constraints are well recognized as an important extension of answer-set programming.  ...  The goal of this paper is to apply the notion of treewidth to programs with cardinality or weight constraints and to identify tractable fragments.  ...  A program with weight constraints (PWC) is a triple Π = (A, C, R), where A is a set of atoms, C is a set of weight constraints (or constraints for short), and R is a set of rules.  ...
