propagate_ineqs_tactic.h
|
|
|
|
Abstract:
|
|
|
|
This tactic performs the following tasks:
|
|
|
|
- Propagate bounds using the bound_propagator.
|
|
- Eliminate subsumed inequalities.
|
|
For example:
|
|
x - y >= 3
|
|
can be replaced with true if we know that
|
|
x >= 3 and y <= 0
|
|
|
|
- Convert inequalities of the form p <= k and p >= k into p = k,
|
|
where p is a polynomial and k is a constant.
|
|
|
|
This strategy assumes the input is in arith LHS mode.
|
|
This can be achieved by using option :arith-lhs true in the
|
|
simplifier.
