Abstract:
|
|
|
|
Fix a difference logic variable to 0.
|
|
If the problem is in the difference logic fragment, that is, all arithmetic terms
|
|
are of the form (x + k), and the arithmetic atoms are of the
|
|
form x - y <= k or x - y = k. Then, we can set one variable to 0.
|
|
|
|
This is useful because, many bounds can be exposed after this operation is performed.
