SMT-based Constraint Answer Set Solver EZSMT+ (1905.03334v2)
Published 8 May 2019 in cs.LO and cs.AI
Abstract: Constraint answer set programming integrates answer set programming with constraint processing. System EZSMT+ is a constraint answer set programming tool that utilizes satisfiability modulo theory solvers for search. Its theoretical foundation lies on generalizations of Niemela's characterization of answer sets of a logic program via so called level rankings.
