Definition at line 54 of file BlisBranchObjectInt.h.

BlisBranchObjectInt::BlisBranchObjectInt ( BlisModel model,
int  varInd,
int  direction,
double  value 
) [inline]

Construct a branching object, which branching on variable varInd.

Parameters:
varIndthe index of integer variable in object set
directionthe direction of first branching: 1(up), -1(down)
valuethe fractional solution value of variable varInd

Definition at line 70 of file BlisBranchObjectInt.h.

BlisBranchObjectInt::BlisBranchObjectInt ( BlisModel model,
int  varInd,
int  intScore,
double  dblScore,
int  direction,
double  value 
) [inline]

Construct a branching object, which branching on variable varInd.

Parameters:
varIndthe index of integer variable in object set
intScorethe integer score/goodness
dblScorethe double score/goodness
