The design and implementation of the model constructing satisfiability calculus
Dejan Jovanović, Clark Barrett, Leonardo de Moura · 2013
We present the design and implementation of the Model Constructing Satisfiability (MCSat) calculus. The MCSat calculus generalizes ideas found in CDCL-style propositional SAT solvers to SMT solvers, and provides a common framework where recent model-based procedures and techniques can be justified and combined. We describe how to incorporate support for linear real arithmetic and uninterpreted function symbols m the calculus. We report encouraging experimental results, where MCSat performs competitive with the state-of-the art SMT solvers without using pre-processing techniques and ad-hoc optimizations. The implementation is flexible, additional plugins can be easily added, and the code is freely available.
