clingcon

Extension of clingo to handle constraints over integers

Clingcon is an answer set solver for constraint logic programs, building upon the answer set solver clingo. It extends the high-level modeling language of ASP with constraint solving capacities. Constraints over finite domain integer variables can be used in logic programs. Clingcon adopts state-of-the-art techniques from the area of SMT, like conflict-driven learning and theory propagation. It uses lazy nogood and variable generation on the order encoding and features several preprocessing techniques.
