SM-based Semantics for Answer Set Programs Containing Conditional Literals and Arithmetic
Zachary Hansen, Yuliya Lierler
Modern answer set programming solvers such as CLINGO support advanced language constructs that improve the expressivity and conciseness of logic programs. Conditional literals are…
Anthem 2.0: Automated Reasoning for Answer Set Programming
Jorge Fandinno, Christoph Glinzer, Zachary Hansen +5
Anthem 2.0 is a tool to aid in the verification of logic programs written in an expressive fragment of Clingo's input language named mini-gringo, which includes arithmetic operatio…
Recursive Aggregates as Intensional Functions in Answer Set Programming: Semantics and Strong Equivalence
Jorge Fandinno, Zachary Hansen
This paper shows that the semantics of programs with aggregates implemented by the solvers clingo and dlv can be characterized as extended First-Order formulas with intensional fun…
External Behavior of a Logic Program and Verification of Refactoring
Jorge Fandinno, Zachary Hansen, Yuliya Lierler +2
Refactoring is modifying a program without changing its external behavior. In this paper, we make the concept of external behavior precise for a simple answer set programming langu…
