## Tactic normalize-bounds
|
|
|
|
### Short Description
|
|
|
|
Replace $x$ with $x' + l$, when $l \leq x$
|
|
where $x'$ is a fresh variable.
|
|
Note that, after the transformation $0 \leq x'$.
|
|
|
|
### Example
|
|
|
|
```z3
|
|
(declare-const x Int)
|
|
(declare-const y Int)
|
|
(declare-const z Int)
|
|
(assert (<= 3 x))
|
|
(assert (<= (+ x y) z))
|
|
(apply normalize-bounds)
|
|
```
|
|
|
|
