Member Function Documentation

setRelibility()

void BlisBranchStrategyPseudo::setRelibility ( int  rel )

inline

Set relibility.

Definition at line 70 of file BlisBranchStrategyPseudo.h.

clone()

virtual BcpsBranchStrategy * BlisBranchStrategyPseudo::clone ( ) const

inlinevirtual

Clone a brancing strategy.

Implements BcpsBranchStrategy.

Definition at line 73 of file BlisBranchStrategyPseudo.h.

betterBranchObject()

virtual int BlisBranchStrategyPseudo::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.

createCandBranchObjects()

virtual int BlisBranchStrategyPseudo::createCandBranchObjects ( int  numPassesLeft, double  ub  )

virtual

Create a set of candidate branching objects.

Reimplemented from BcpsBranchStrategy.
