## Detailed Description

Cut branching object.

This object can specify a two-way branch in terms of two cuts

Definition at line 108 of file CbcBranchCut.hpp.

## Constructor & Destructor Documentation

CbcCutBranchingObject::CbcCutBranchingObject | ( |  | ) |

Default constructor.

CbcCutBranchingObject::CbcCutBranchingObject | ( | CbcModel * | model,
|  | OsiRowCut & | down,
|  | OsiRowCut & | up,
|  | bool | canFix |
| ) |  |  |

Create a cut branching object.

Cut down will applied on way=-1, up on way==1 Assumed down will be first so way_ set to -1

CbcCutBranchingObject::CbcCutBranchingObject | ( | const CbcCutBranchingObject & |  | ) |

Copy constructor.

virtual CbcCutBranchingObject::~CbcCutBranchingObject | ( |  | ) | `[virtual]`

Destructor.

## Member Function Documentation

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

Assignment operator.

Reimplemented from CbcBranchingObject.

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

Clone.

Implements CbcBranchingObject.

virtual double CbcCutBranchingObject::branch | ( |  | ) | `[virtual]`

Sets the bounds for variables or adds a cut depending on the current arm of the branch and advances the object state to the next arm.

Returns change in guessed objective on next branch

Implements CbcBranchingObject.

virtual void CbcCutBranchingObject::print | ( |  | ) | `[virtual]`

Print something about branch - only if log level high.

virtual bool CbcCutBranchingObject::boundBranch | ( |  | ) | const`[virtual]`

Return true if branch should fix variables.

Reimplemented from OsiBranchingObject.

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

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

Implements CbcBranchingObject.

Definition at line 151 of file CbcBranchCut.hpp.

virtual int CbcCutBranchingObject::compareOriginalObject | ( | const CbcBranchingObject * | brObj | ) | const`[virtual]`

Compare the original object of `this` with the original object of `brObj`.

Assumes that there is an ordering of the original objects. This method should be invoked only if `this` and brObj are of the same type. Return negative/0/positive depending on whether `this` is smaller/same/larger than the argument.

virtual CbcRangeCompare CbcCutBranchingObject::compareBranchingObject | ( | const CbcBranchingObject * | brObj,
|  | const bool | replaceIfOverlap = `false` |
| ) |  |  | `[virtual]`

Compare the `this` with `brObj`.

`this` and `brObj` must be os the same type and must have the same original object, but they may have different feasible regions. Return the appropriate CbcRangeCompare value (first argument being the sub/superset if that's the case). In case of overlap (and if `replaceIfOverlap` is true) replace the current branching object with one whose feasible region is the overlap.
