Constructor & Destructor Documentation

◆ BlisBranchObjectInt() [1/5]

BlisBranchObjectInt::BlisBranchObjectInt ( )
inline

Default constructor.

Definition at line 52 of file BlisBranchObjectInt.h.

◆ BlisBranchObjectInt() [2/5]

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 68 of file BlisBranchObjectInt.h.

◆ BlisBranchObjectInt() [3/5]

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
directionthe direction of first branching: 1(up), -1(down)
valuethe fractional solution value of variable varInd

Definition at line 99 of file BlisBranchObjectInt.h.

◆ BlisBranchObjectInt() [4/5]

BlisBranchObjectInt::BlisBranchObjectInt ( BlisModel * model,
int varInd,
int direction,
double lowerValue,
double upperValue )
inline

Create a degenerate branching object.

Specifies a ‘one-direction branch’. Calling branch() for this object will always result in lowerValue <= x <= upperValue. Used to fix a variable when lowerValue = upperValue.

Definition at line 130 of file BlisBranchObjectInt.h.

◆ BlisBranchObjectInt() [5/5]

BlisBranchObjectInt::BlisBranchObjectInt ( const BlisBranchObjectInt & )

Copy constructor.

◆ ~BlisBranchObjectInt()

virtual BlisBranchObjectInt::~BlisBranchObjectInt ( )
inlinevirtual

Destructor.

Definition at line 158 of file BlisBranchObjectInt.h.

Member Function Documentation

◆ operator=()

BlisBranchObjectInt & BlisBranchObjectInt::operator= ( const BlisBranchObjectInt & rhs)

Assignment operator.

◆ clone()

virtual BcpsBranchObject * BlisBranchObjectInt::clone ( ) const
inlinevirtual

Clone.

Definition at line 153 of file BlisBranchObjectInt.h.

◆ branch()

virtual double BlisBranchObjectInt::branch ( bool normalBranch = false)
virtual

Set the bounds for the variable according to the current arm of the branch and advances the object state to the next arm.

Returns change in guessed objective on next branch.

◆ print()

virtual void BlisBranchObjectInt::print ( bool normalBranch)
virtual

Print something about branch - only if log level high.

◆ getDown()

const double * BlisBranchObjectInt::getDown ( ) const
inline

Get down arm bounds.

Definition at line 169 of file BlisBranchObjectInt.h.

◆ getUp()

const double * BlisBranchObjectInt::getUp ( ) const
inline

Get upper arm bounds.

Definition at line 172 of file BlisBranchObjectInt.h.

◆ encodeBlis()

AlpsReturnStatus BlisBranchObjectInt::encodeBlis ( AlpsEncoded * encoded) const
inlineprotected

Pack Blis portion to an encoded object.

Definition at line 177 of file BlisBranchObjectInt.h.

◆ decodeBlis()

AlpsReturnStatus BlisBranchObjectInt::decodeBlis ( AlpsEncoded & encoded)
inlineprotected

Unpack Blis portion from an encoded object.

Definition at line 193 of file BlisBranchObjectInt.h.

◆ encode()

virtual AlpsReturnStatus BlisBranchObjectInt::encode ( AlpsEncoded * encoded) const
inlinevirtual

Pack to an encoded object.

Definition at line 210 of file BlisBranchObjectInt.h.
