## Detailed Description

Simple branching object for an integer variable with pseudo costs.

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.

## Constructor & Destructor Documentation

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.

## Member Function Documentation

CbcDynamicPseudoCostBranchingObject& CbcDynamicPseudoCostBranchingObject::operator= | ( | const CbcDynamicPseudoCostBranchingObject & | rhs | ) |

Assignment operator.

Reimplemented from CbcIntegerBranchingObject.

virtual CbcBranchingObject* CbcDynamicPseudoCostBranchingObject::clone | ( |  | ) | const`[virtual]`

Clone.

Reimplemented from CbcIntegerBranchingObject.

void CbcDynamicPseudoCostBranchingObject::fillPart | ( | int | variable,
|  | int | way,
|  | double | value,
|  | CbcSimpleIntegerDynamicPseudoCost * | object |
| ) |  |  |

Does part of constructor.

virtual double CbcDynamicPseudoCostBranchingObject::branch | ( |  | ) | `[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

Reimplemented from CbcBranchingObject.

double CbcDynamicPseudoCostBranchingObject::changeInGuessed | ( |  | ) | const`[inline]`

Change in guessed.

Definition at line 170 of file CbcBranchDynamic.hpp.

void CbcDynamicPseudoCostBranchingObject::setChangeInGuessed | ( | double | value | ) | `[inline]`

Set change in guessed.

Definition at line 174 of file CbcBranchDynamic.hpp.

CbcSimpleIntegerDynamicPseudoCost* CbcDynamicPseudoCostBranchingObject::object | ( |  | ) | const`[inline]`

Return object.

Reimplemented from CbcBranchingObject.

Definition at line 178 of file CbcBranchDynamic.hpp.

void CbcDynamicPseudoCostBranchingObject::setObject | ( | CbcSimpleIntegerDynamicPseudoCost * | object | ) | `[inline]`

Set object.

Definition at line 182 of file CbcBranchDynamic.hpp.

virtual CbcBranchObjType CbcDynamicPseudoCostBranchingObject::type | ( |  | ) | const`[inline, virtual]`

Return the type (an integer identifier) of `this`.

Reimplemented from CbcIntegerBranchingObject.
