Specialization of LocalSearchOperator built from an array of IntVars which specifies the scope of the operator. This class also takes care of storing current variable values in Start(), keeps track of changes done by the operator and builds the delta. The Deactivate() method can be used to perform Large Neighborhood Search.

This method should not be overridden.
Override OnStart() instead which is called before exiting this method.

| bool operations_research::IntVarLocalSearchOperator::MakeNextNeighbor | ( | Assignment * | delta, | |
| Assignment * | deltadelta | |||
| ) | [virtual] |
Redefines MakeNextNeighbor to export a simpler interface.
The calls to ApplyChanges() and RevertChanges() are factored in this method, hiding both delta and deltadelta from subclasses which only need to override MakeOneNeighbor(). Therefore this method should not be overridden. Override MakeOneNeighbor() instead.
Implements operations_research::LocalSearchOperator.
Reimplemented in operations_research::MakePairActiveOperator.
Definition at line 202 of file local_search.cc.
| bool operations_research::IntVarLocalSearchOperator::MakeOneNeighbor | ( | ) | [protected, virtual] |
Creates a new neighbor.
It returns false when the neighborhood is completely explored.
Reimplemented in operations_research::BaseLNS, operations_research::ChangeValue, and operations_research::PathOperator.
