Illegal Assignment operator.

virtual BcpsBranchStrategy* BlisBranchStrategyBilevel::clone ( ) const

inlinevirtual

Clone a brancing strategy.

Implements BcpsBranchStrategy.

Definition at line 58 of file BlisBranchStrategyBilevel.h.

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.
