Branching object for unordered cliques.
Intended for cliques which are long enough to make it worthwhile but <= 64 members. There will also be ones for long cliques.
Variable_ is the clique id number (redundant, as the object also holds a pointer to the clique.

virtual int CbcCliqueBranchingObject::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.
Reimplemented from CbcBranchingObject.
virtual CbcRangeCompare CbcCliqueBranchingObject::compareBranchingObject | ( | const CbcBranchingObject * | brObj, |
const bool | replaceIfOverlap = false |
||
) | [virtual] |
Compare the this
with brObj
.
this
and brObj
must be of 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.
