virtual bool QueenArmies::QueenBranch::status ( const Space * home ) const [inline, virtual]

Check status of branching, return true if alternatives left.
This method is called when Space::status is called, it determines whether to continue branching with this branching or move on to the (possibly) next branching.
Implements Gecode::Branching.
Definition at line 145 of file queen-armies.cc.

virtual BranchingDesc* QueenArmies::QueenBranch::description ( const Space * ) const [inline, virtual]

Return branching description.
Note that this method can rely on the fact that it is called immediately after a previous call to status. Hence, it is safe to remember computation from status in order to speed up description.
Implements Gecode::Branching.

virtual ExecStatus QueenArmies::QueenBranch::commit ( Space * home,

const BranchingDesc * d,

unsigned int a

) [inline, virtual]

Commit for branching description d and alternative a.
The current branching in the space home performs a commit from the information provided by the branching description d and the alternative a.
Implements Gecode::Branching.

virtual Actor* QueenArmies::QueenBranch::copy ( Space * home,

bool share

) [inline, virtual]

Create copy.

Implements Gecode::Actor.
