Detailed Description

Class to validate or reject a cut.

Definition at line 26 of file CglLandPValidator.hpp.

Member Enumeration Documentation

◆ 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
