Detailed Description

Derived class of BrCand, it defines candidates for branching on bounds SOS type 1 and 2 constraints.

Member Function Documentation

◆ getDDist()

double SOSBrCand::getDDist ( )

virtual

Return the distance of the current point from the branching constraint: down direction. For an integer constrained variable, x, it would be $x - \lfloor x \rfloor$ .

Implements Minotaur::BrCand.

◆ getName()

std::string SOSBrCand::getName ( ) const

virtual

Display for debugging.

Reimplemented from Minotaur::BrCand.

◆ getUDist()

double SOSBrCand::getUDist ( )

virtual

Return the distance of the current point from the branching constraint: up direction For an integer constrained variable, x, it would be $x - \lceil x \rceil$ .

Implements Minotaur::BrCand.
