Module Name:

    sat_tactic.cpp

Abstract:

    Tactic for using the SAT solver and its preprocessing capabilities.
    
Author:

    Leonardo (leonardo) 2011-10-26

Tactic Documentation:

## Tactic sat

### Short Description

Try to solve goal using a SAT solver

## Tactic sat-preprocess

### Short Description 

Apply SAT solver preprocessing procedures (bounded resolution, Boolean constant propagation, 2-SAT, subsumption, subsumption resolution).

### Example

```z3
(declare-const a Bool)
(declare-const b Bool)
(declare-const c Bool)
(declare-const d Bool)
(declare-const e Bool)
(declare-const f Bool)
(declare-fun p (Bool) Bool)
(assert (=> a b))
(assert (=> b c))
(assert a)
(assert (not c))
(apply sat-preprocess)
```
