◆ HasFragments()

virtual bool operations_research::LocalSearchOperator::HasFragments ( ) const
inlinevirtualinherited

Reimplemented in operations_research::BaseLns.

Definition at line 815 of file constraint_solveri.h.

◆ HoldsDelta()

template<class V, class Val, class Handler>
bool operations_research::VarLocalSearchOperator< V, Val, Handler >::HoldsDelta ( ) const
inlineoverridevirtualinherited

Reimplemented from operations_research::LocalSearchOperator.

Definition at line 830 of file constraint_solveri.h.

◆ IsIncremental()

virtual bool operations_research::VarLocalSearchOperator< V, Val, Handler >::IsIncremental ( ) const
inlinevirtualinherited

Definition at line 846 of file constraint_solveri.h.

◆ MakeNextNeighbor()

virtual bool operations_research::LocalSearchOperator::MakeNextNeighbor ( Assignment *  delta,
Assignment *  deltadelta 
)
pure virtualinherited

Implemented in operations_research::IntVarLocalSearchOperator, operations_research::PairNodeSwapActiveOperator< swap_first >, operations_research::IndexPairSwapActiveOperator, operations_research::SwapIndexPairOperator, and operations_research::MakePairActiveOperator.

◆ MarkChange()

template<class V, class Val, class Handler>
void operations_research::VarLocalSearchOperator< V, Val, Handler >::MarkChange ( int64  index)
inlineprotectedinherited

OnStart() should really be protected, but then SWIG doesn't see it.

So we make it public, but only subclasses should access to it (to override it).

Definition at line 932 of file constraint_solveri.h.

◆ OldSequence()

const std::vector<int>& operations_research::SequenceVarLocalSearchOperator::OldSequence ( int64  index) const
inline

Definition at line 1112 of file constraint_solveri.h.

Definition at line 857 of file constraint_solveri.h.

◆ OnStart()

template<class V, class Val, class Handler>
virtual void operations_research::VarLocalSearchOperator< V, Val, Handler >::OnStart ( )
inlinevirtualinherited

Called by Start() after synchronizing the operator with the current assignment.

Should be overridden instead of Start() to avoid calling VarLocalSearchOperator::Start explicitly.

Reimplemented in operations_research::SwapIndexPairOperator.

Definition at line 927 of file constraint_solveri.h.

◆ Reset()

virtual void operations_research::LocalSearchOperator::Reset ( )
inlinevirtualinherited

Reimplemented in operations_research::PathOperator.

void operations_research::SequenceVarLocalSearchOperator::SetForwardSequence ( int64  index,
const std::vector< int > &  value

Definition at line 847 of file constraint_solveri.h.

◆ SkipUnchanged()

template<class V, class Val, class Handler>
virtual bool operations_research::VarLocalSearchOperator< V, Val, Handler >::SkipUnchanged ( int  index) const
inlinevirtualinherited

Reimplemented in operations_research::PathOperator.

Definition at line 856 of file constraint_solveri.h.

◆ Start()

template<class V, class Val, class Handler>
void operations_research::VarLocalSearchOperator< V, Val, Handler >::Start ( const Assignment *  assignment)
inlineoverridevirtualinherited

This method should not be overridden.

Override OnStart() instead which is called before exiting this method.

Implements operations_research::LocalSearchOperator.

Definition at line 833 of file constraint_solveri.h.

◆ Value()

template<class V, class Val, class Handler>
const Val& operations_research::VarLocalSearchOperator< V, Val, Handler >::Value ( int64  index) const
