Protected Attributes | |
double | changeInGuessed_ |
Change in guessed objective value for next branch. | |
CbcSimpleIntegerDynamicPseudoCost * | object_ |
Pointer back to object. |
This object can specify a two-way branch on an integer variable. For each arm of the branch, the upper and lower bounds on the variable can be independently specified.
Variable_ holds the index of the integer variable in the integerVariable_ array of the model.

CbcDynamicPseudoCostBranchingObject::CbcDynamicPseudoCostBranchingObject | ( | ) |
Default constructor.
CbcDynamicPseudoCostBranchingObject::CbcDynamicPseudoCostBranchingObject | ( | CbcModel * | model, | |
int | variable, | |||
int | way, | |||
double | value, | |||
CbcSimpleIntegerDynamicPseudoCost * | object | |||
) |
Create a standard floor/ceiling branch object.
Specifies a simple two-way branch. Let value
= x*. One arm of the branch will be is lb <= x <= floor(x*), the other ceil(x*) <= x <= ub. Specify way = -1 to set the object state to perform the down arm first, way = 1 for the up arm.
CbcDynamicPseudoCostBranchingObject::CbcDynamicPseudoCostBranchingObject | ( | CbcModel * | model, | |
int | variable, | |||
int | way, | |||
double | lowerValue, | |||
double | upperValue | |||
) |
Create a degenerate branch object.
Specifies a `one-way branch'. Calling branch() for this object will always result in lowerValue <= x <= upperValue. Used to fix a variable when lowerValue = upperValue.
CbcDynamicPseudoCostBranchingObject::CbcDynamicPseudoCostBranchingObject | ( | const CbcDynamicPseudoCostBranchingObject & | ) |
Copy constructor.
virtual CbcDynamicPseudoCostBranchingObject::~CbcDynamicPseudoCostBranchingObject | ( | ) | [virtual] |
Destructor.
CbcDynamicPseudoCostBranchingObject& CbcDynamicPseudoCostBranchingObject::operator= | ( | const CbcDynamicPseudoCostBranchingObject & | rhs | ) |
Assignment operator.
virtual CbcBranchingObject* CbcDynamicPseudoCostBranchingObject::clone | ( | ) | const [virtual] |
virtual double CbcDynamicPseudoCostBranchingObject::branch | ( | bool | normalBranch = false |
) | [virtual] |
Sets the bounds for the variable according to the current arm of the branch and advances the object state to the next arm.
This version also changes guessed objective value
Reimplemented from CbcIntegerBranchingObject.
virtual int CbcDynamicPseudoCostBranchingObject::fillStrongInfo | ( | CbcStrongInfo & | info | ) | [virtual] |
Some branchingObjects may claim to be able to skip strong branching.
If so they have to fill in CbcStrongInfo. The object mention in incoming CbcStrongInfo must match. Returns nonzero if skip is wanted
