## Member Function Documentation

BlisBranchStrategyBilevel& BlisBranchStrategyBilevel::operator= | ( | const BlisBranchStrategyBilevel & | rhs | ) | `[private]`

Illegal Assignment operator.

virtual BcpsBranchStrategy* BlisBranchStrategyBilevel::clone | ( |  | ) | const`[inline, virtual]`

Clone a brancing strategy.

Implements BcpsBranchStrategy.

References BlisBranchStrategyBilevel().

virtual int BlisBranchStrategyBilevel::createCandBranchObjects | ( | int | numPassesLeft,
|  | double | ub |
| ) |  |  | `[virtual]`

Create a set of candidate branching objects.

Reimplemented from BcpsBranchStrategy.

virtual int BlisBranchStrategyBilevel::betterBranchObject | ( | BcpsBranchObject * | thisOne,
|  | BcpsBranchObject * | bestSoFar |
| ) |  |  | `[virtual]`

Compare branching object thisOne to bestSoFar.

If thisOne is better than bestObject, return branching direction(1 or -1), otherwise return 0. If bestSorFar is NULL, then always return branching direction(1 or -1).

Implements BcpsBranchStrategy.
