## Member Enumeration Documentation

enum LAP::Validator::RejectionsReasons

Reasons for rejecting a cut.

Enumerator
NoneAccepted |
SmallViolation | Violation of the cut is too small.
SmallCoefficient | There is a small coefficient we can not get rid off.
BigDynamic | Dynamic of coefficinet is too important.
DenseCut | cut is too dense
EmptyCut | After cleaning cut has become empty.
DummyEnd | dummy
