Overview

Clingcon is an answer set solver for (extended) constraint normal logic programs. It combines the high-level modeling capacities of Answer Set Programming (ASP) with constraint solving. Constraints over non-linear finite integers can be used in the logic programs. The primary clingcon algorithm adopts state-of-the-art techniques from SMT and uses conflict-driven learning and theory propagation for the CSP solver.

Clingcon

Clingcon incorporates all features of clasp and extends them by SMT related features including:

• theory propagation
• lazy learning
• use of conflict and reason filtering methods

To get an idea on how to model in Clingcon, consult the following examples:

• breakfast example
• bucket example
• send more money
• squares problem
