## 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)
|
|
```
