Detailed Description
Base-class for branchings.Note that branchings cannot be created inside a propagator (no idea why one would like to do that anyway). If you do that the system will explode in a truly interesting way.

Member Function Documentation
| virtual bool Gecode::Branching::status | ( | const Space & | home | ) | const [pure 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.
Implemented in BlackHoleBranch, QueenArmies::QueenBranch, Radiotherapy::NestedSearch, SteelMill::SteelMillBranch, Gecode::FunctionBranch, Gecode::ViewBranching< ViewSel >, and Gecode::ViewBranching< ViewSel >.
| virtual const BranchingDesc* Gecode::Branching::description | ( | Space & | home | ) | [pure virtual] |
Return branching description.
Note that this method relies on the fact that it is called immediately after a previous call to status. Moreover, the member function can only be called once.
Implemented in BlackHoleBranch, QueenArmies::QueenBranch, Radiotherapy::NestedSearch, SteelMill::SteelMillBranch, Gecode::Int::Branch::ViewValuesBranching< ViewSel, View >, Gecode::FunctionBranch, and Gecode::ViewValBranching< ViewSel, ValSel >.
| virtual ExecStatus Gecode::Branching::commit | ( | Space & | home, | |
| const BranchingDesc & | d, | |||
| unsigned int | a | |||
| ) | [pure 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.
Implemented in BlackHoleBranch, QueenArmies::QueenBranch, Radiotherapy::NestedSearch, SteelMill::SteelMillBranch, Gecode::Int::Branch::ViewValuesBranching< ViewSel, View >, Gecode::FunctionBranch, and Gecode::ViewValBranching< ViewSel, ValSel >.
