Explanations for Answer Set Programming

1 code implementation30 Aug 2023 Mario Alviano, Ly Ly Trieu, Tran Cao Son, Marcello Balduccini

Different from xASP, the new system, xASP2, supports different clingo constructs like the choice rules, the constraints, and the aggregates such as #sum, #min.

Answer Set Planning: A Survey

no code implementations11 Feb 2022 Tran Cao Son, Enrico Pontelli, Marcello Balduccini, Torsten Schaub

Answer Set Planning refers to the use of Answer Set Programming (ASP) to compute plans, i. e., solutions to planning problems, that transform a given state of the world to another state.

Specifying and Reasoning about CPS through the Lens of the NIST CPS Framework

1 code implementation14 Jan 2022 Thanh Hai Nguyen, Matthew Bundas, Tran Cao Son, Marcello Balduccini, Kathleen Campbell Garwood, Edward R. Griffor

This paper introduces a formal definition of a Cyber-Physical System (CPS) in the spirit of the CPS Framework proposed by the National Institute of Standards and Technology (NIST).

exp(ASPc) : Explaining ASP Programs with Choice Atoms and Constraint Rules

no code implementations17 Sep 2021 Ly Ly Trieu, Tran Cao Son, Marcello Balduccini

We present an enhancement of exp(ASP), a system that generates explanation graphs for a literal l - an atom a or its default negation ~a - given an answer set A of a normal logic program P, which explain why l is true (or false) given A and P. The new system, exp(ASPc), differs from exp(ASP) in that it supports choice rules and utilizes constraint rules to provide explanation graphs that include information about choices and constraints.

Ontology-Based Reasoning about the Trustworthiness of Cyber-Physical Systems

no code implementations20 Mar 2018 Marcello Balduccini, Edward Griffor, Michael Huth, Claire Vishik, Martin Burns, David Wollman

The example analyzed in the paper demonstrates the enrichment of the original CPS model obtained through ontology and reasoning and its ability to deliver additional insights to the developers and operators of CPS.

CASP Solutions for Planning in Hybrid Domains

no code implementations12 Apr 2017 Marcello Balduccini, Daniele Magazzeni, Marco Maratea, Emily LeBlanc

CASP is an extension of ASP that allows for numerical constraints to be added in the rules.

Constraint Answer Set Solver EZCSP and Why Integration Schemas Matter

no code implementations14 Feb 2017 Marcello Balduccini, Yuliya Lierler

One of the main contributions of this paper is the first comprehensive account of the constraint answer set language and solver EZCSP, a mainstream representative of this research area that has been used in various successful applications.
