## Tactic add-bounds
|
|
|
|
### Short Description
|
|
|
|
Tactic for bounding unbounded variables.
|
|
|
|
### Long Description
|
|
|
|
The tactic creates a stronger sub-goal by adding bounds to variables.
|
|
The new goal may not be satisfiable even if the original goal is.
|
|
|
|
### Example
|
|
|
|
```z3
|
|
(declare-const x Int)
|
|
(declare-const y Int)
|
|
(assert (> (+ x y) 10))
|
|
(apply add-bounds)
|
|
```
